Juan Martín del Potro Lucas (Spanish pronunciation: [xwan ma?'tin del 'pot?o]) (born 23 September 1988), nicknamed Delpo (IPA: ['delpo]), is an Argentine professional tennis player who is currently ranked world No. 122 in men's singles by the Association of Tennis Professionals (ATP).
His biggest achievement has been winning the 2009 US Open, defeating Rafael Nadal in the semifinal and 5-time defending champion Roger Federer in the final. He was the first to defeat both Federer and Nadal during the same major and was the only man outside the Big Four to win a major between the 2005 French Open and the 2013 US Open, a span of 35 tournaments. He is also the second Argentine and the fifth-youngest man to win the US Open in the Open Era. Other career highlights include reaching the 2018 US Open final, winning the bronze medal in men's singles at the 2012 London Olympics, the silver medal at the 2016 Rio Olympics, the Indian Wells Masters in 2018, and being part of his country's successful Davis Cup team; but his career has also been hampered by a succession of wrist injuries.
Del Potro achieved a top-10 ranking by the Association of Tennis Professionals (ATP) for the first time on 6 October 2008. In January 2010, he reached a ranking of world No. 4, after which del Potro had to withdraw from most of the tournaments in 2010 due to a right wrist injury. He returned in 2011 and was back to world No. 4 in January 2014 but had to withdraw from competition due to another wrist injury, but this time to his left wrist.
He again returned to the ATP World Tour in February 2016 after a long injury-induced absence. At the 2016 Summer Olympics he discovered a huge vein of form, defeating World No. 1 Novak Djokovic in straight sets in the first round and No. 3 Rafael Nadal in the semi-finals, claiming silver after falling in the final to No. 2 Andy Murray in four attritional sets. Only weeks later, Murray and del Potro met again in the Davis Cup semi-final in Glasgow, with del Potro emerging victorious in five sets. He then led Argentina to their first ever Davis Cup victory by defeating Croatia's Marin ?ili? in the final in Zagreb from two sets down. He reached his first major semi-final since 2013 by defeating Roger Federer in the quarter-finals of the 2017 US Open. In 2018, he won his first Masters 1000 title at the Indian Wells Masters, defeating defending champion and World No. 1 Roger Federer in the final. After reaching the semi-finals of the 2018 French Open, he again matched his career high of No. 4. Finally, in August, he achieved the World No. 3 ranking for the very first time. At the 2018 US Open, he reached his second Grand Slam final.
Having started playing tennis at the age of seven, del Potro won his first senior match (ITF level) in 2004 at the age of 15. At the start of the 2006 season, at 17 years of age he notched his first ATP Tour match win against world No. 117, Albert Portas. In 2008, he became the first player in ATP history to win his first four career titles in as many tournaments. He also completed the second-longest winning streak in 2008, and the second longest by a teenager in the Open Era with his winning sequence spanning 23 matches over five tournaments, falling just one short of Rafael Nadal.
Juan Martín del Potro was born in Tandil, Argentina. His father, Daniel del Potro, played semi-professional rugby union in Argentina and is a veterinarian. His mother, Patricia Lucas, is a teacher and he has a younger sister named Julieta. He also had an elder sister who died when she was 8 years old in a car accident. Del Potro speaks Spanish, English and some Italian.
Aside from tennis, he enjoys playing association football and supports the Boca Juniors team in Argentina and Juventus in Italy. He would often dedicate time to both sports during his youth, and Argentine-Italian international footballer Mauro Camoranesi, who grew up in the same town, remains a close friend of del Potro.
Del Potro began playing tennis at the age of seven with coach Marcelo Gómez (who also coached Tandil-born players Juan Mónaco, Mariano Zabaleta and Máximo González). Del Potro's talent was discovered by Italian ex-tennis professional Ugo Colombini, who accompanied him through the initial phases of his young career, and is still today his agent and close friend. When questioned about his ambitions in tennis he replied, "I dream of winning a Grand Slam and the Davis Cup." Despite refusing to participate in the Davis Cup several times, he has since achieved both goals. He is a Roman Catholic.
As a junior in 2002, del Potro won the Orange Bowl 14s title, beating Marin ?ili? en route to a victory over Pavel Tchekov in the final. In 2003, at the age of 14, del Potro received wild cards to three ITF Circuit events in Argentina, where he lost in straight sets in the first round of each.
As a junior, del Potro reached as high as No. 3 in the combined junior world rankings in January 2005.
In May 2004, del Potro won his first senior match, at the age of 15, at the ITF Circuit event in Buenos Aires by defeating Matias Niemiz. He then went on to lose in three sets to Sebastián Decoud in the second round. His next victory came over five months later against the Chilean Álvaro Loyola in a tournament in Antofagasta. Later that year, del Potro reached the quarterfinals of the ITF Circuit event in Campinas, Brazil; recording victories over Henrique Mello and Alessandro Camarco. Del Potro won two more matches before the end of the year and saw his world ranking rise from no. 1441 in August to no. 1077 in November. He also reached the finals in the Argentina Cup and Campionati Internazionali D'Italia Junior tournaments.
Del Potro reached his first final of the ITF Junior Circuit on 11 January 2005, the "Copa del Cafe (Coffee Bowl)" Junior ITF Tournament in Costa Rica, where he lost to Robin Haase in three sets. He was involved in a dispute with the umpire during this match, who decided to stop play because of rain, which del Potro believed favoured Haase. Because of the rain delays, the final set had to be played indoors; this was the first time the indoor courts had been used in the 44-year history of the youth tournament.
At the age of 16, del Potro reached his first senior singles final at the Futures tournament in Berimbau Naucalpan, Mexico, where he lost to Darko Madjarovski. He then went on to win consecutive titles at two Future ITF Circuit events in Santiago, Chile, including the 26th International Junior tournament. In the first tournament, he beat Jorge Aguilar, and in the second, he did not drop a set in the whole tournament and defeated Thiago Alves in the final, a player ranked more than 400 places higher at the time. He won his third title in his home country by defeating Damián Patriarca, who forfeited the match, at the ITF Circuit event in Buenos Aires.
Del Potro turned professional after the Italy F17 event in Bassano, and in his first professional tournament, the Lines Trophy in Reggio Emilia, he reached the semifinals, where he lost to countryman Martín Vassallo Argüello in three sets. Two tournaments later, he reached the final of the Credicard Citi MasterCard Tennis Cup in Campos do Jordão, Brazil, where he lost to André Sá in straight sets. After turning 17, he won the Montevideo Challenger by defeating Boris Pa?anski in the final in three sets. That same year, he failed in his first attempt to qualify for his first Grand Slam, at the US Open, losing in the first round to Paraguayan Ramón Delgado. Throughout 2005, del Potro jumped over 900 positions to finish with a world ranking of no. 157, largely due to winning three Futures tournaments. He was the youngest player to finish in the year-end top 200.
In February, del Potro played his first ATP tour event in Viña del Mar, where he defeated Albert Portas, before losing to Fernando González in the second round. Later, seeded seventh, he won the Copa Club Campestre de Aguascalientes by defeating the likes of Dick Norman and Thiago Alves, before beating Sergio Roitman in the final.
Del Potro qualified for the main draw of his first Grand Slam in the 2006 French Open at the age of 17. He lost in the opening round to former French Open champion and 24th seed Juan Carlos Ferrero. Having received a wild card, he reached the quarterfinals of the ATP event in Umag, Croatia, where he lost in three sets to the eventual champion, Stanislas Wawrinka. In Spain, he participated in the Open Castilla y León Challenger tournament held in Segovia, defeating top seed Fernando Verdasco in the quarterfinals and Benjamin Becker in the final.
Del Potro qualified for his first US Open in 2006, after being seeded ninth in the qualifying stages, where he beat Brian Vahaly, Wayne Arthurs, and Daniel Köllerer in straight sets. In the US Open, he lost in the first round to fellow qualifier Alejandro Falla of Colombia in four sets. He went on to qualify for his first ATP Masters Series tournament in Spain, the Mutua Madrileña Madrid Open, where he lost in the first round to Joachim Johansson. After receiving a wild card thanks to Roger Federer, he reached the quarterfinals of the 2006 Davidoff Swiss Indoors in Basel, Switzerland; defeating lucky loser Tobias Clemens in the first round and George Bastl in the second round, before losing to the eventual runner-up Fernando González in three sets. Del Potro finished 2006 as the youngest player in the top 100 at 18 years, 2 months.
Del Potro began the year by reaching his first semifinal in ATP Adelaide, Australia, where he lost to Chris Guccione, having beaten Igor Kunitsyn earlier in the day. He then reached the second round of the Australian Open, where he had to retire because of injury in his match against eventual finalist Fernando González in the fifth set. In February, del Potro played for Argentina in the first round of the Davis Cup against Austria, winning the fourth and deciding match against Jürgen Melzer in five sets, allowing Argentina to qualify for the quarterfinals.
Del Potro defeated Feliciano López before losing to eventual semifinalist Mardy Fish in the second round of the indoor Regions Morgan Keegan Championships. In his next ATP Masters event, he reached the second round of the Pacific Life Open, beating Gustavo Kuerten in the first round, but then losing to Richard Gasquet. Del Potro went further in the Sony Ericsson Open, reaching the fourth round, after he defeated three top-50 players: Jonas Björkman, Marcos Baghdatis, and Mikhail Youzhny, before falling to Rafael Nadal in two sets. In May, he lost in the first round of the French Open to eventual champion Nadal.
In his first grass-court event, del Potro beat Thomas Johansson in two sets and reached the second round at the Queen's Club, where he lost to Nadal. He also reached the quarterfinals in Nottingham the following week; there he beat British qualifier Jamie Baker and Kunitsyn in the first two rounds, but lost to Ivo Karlovi? at the quarterfinal stage. At his inaugural Wimbledon Championships, he defeated Davide Sanguinetti in the first round, before losing to eventual champion Roger Federer in the second round, after a rain delay in the third set.
Del Potro lost to Frank Dancevic in three sets in the second round of the singles at the ATP event in Indianapolis. At the same event, partnered with Travis Parrott in doubles, he won his first doubles tournament, defeating Teymuraz Gabashvili and Karlovi? in the final. He regards this as a special victory, "It was fantastic to play doubles with Parrott. I'm so happy because I've never won a doubles tournament. For the rest of my life, I will remember this tournament." Del Potro qualified for the ATP Masters Series event in Cincinnati, where he reached the third round. He defeated countryman Guillermo Cañas in the first round and Philipp Kohlschreiber in the second, before losing to former world No. 1 Carlos Moyá. At that year's US Open, he defeated Nicolas Mahut and Melzer, before losing to eventual finalist and third seed Novak Djokovic in the third round. He also reached the third round of the Madrid Masters by beating Potito Starace and Tommy Robredo, before losing to eventual champion David Nalbandian in straight sets. In the last tournament of the year, the Paris Masters, he reached the second round, where he lost to Nikolay Davydenko. That year, del Potro was the youngest player to finish in the year-end top 50 at 19 years, 2 months.
Del Potro's first half of the season was hampered by injuries and a change of coach, starting with a first-round loss in Adelaide, where he was the seventh seed. He then made it to the second round of the Australian Open in January, only to retire against David Ferrer due to an injury. Del Potro returned to the circuit in March, winning his first match against Jesse Levine at the Sony Ericsson Open, before losing in the second round to López. Struggling with injuries, his ranking fell as low as no. 81 in April. "At the start of the year, I was playing good, but I had many injuries, many problems with my body, with my physique", said del Potro. "I changed my coach, changed my physical trainer, I changed everything."
In May, del Potro had to retire again, this time in a first-round match against Andy Murray at the Rome Masters. During the second set, the Argentine allegedly made derogatory comments about Murray's mother which resulted in a complaint to the umpire. Del Potro's serve was subsequently broken three times in a row, and he suffered a back injury, which caused his retirement. In his second Grand Slam of the year, the French Open, he was eliminated in the second round by Simone Bolelli in four sets. In June, he reached the semifinals of the Ordina Open, losing to eventual winner and top seed David Ferrer in straight sets. For the second year in a row, he was knocked out of Wimbledon in the second round; he won his first-round clash with Pavel ?nobel in straight sets, but then lost to Stanislas Wawrinka.
A successful summer followed for the Argentine. In July, del Potro and his team decided to remain in Europe to test his fitness. "We decided to play on clay courts for my back because if I start to play again on hard courts, maybe I will injure it again", he recalled. Del Potro won his first career ATP tour title at the Mercedes Cup in Stuttgart, defeating Gasquet in straight sets in the final. A week later, del Potro reached his second career ATP Tour final at the Austrian Open in Kitzbühel, where he beat local hope and sixth seed Melzer in less than an hour, to claim his second title in two weeks. Having competed in just two clay tournaments all of the 2007 season, he never thought he would win his first two titles on clay courts.
In August, del Potro won his third consecutive title at the Countrywide Classic in Los Angeles, beating Andy Roddick in straight sets in the final. After the match, Roddick praised his opponent. "[Del Potro] hits this way and this way kind of equally and he can hit it from inside out and running to it, which is a good thing for him, bad for the rest of us". A fourth consecutive title followed a week later in the Legg Mason Tennis Classic in Washington, D.C., where he recorded a victory over Viktor Troicki, becoming the first player in ATP history to win his first four career titles in as many tournaments. "I don't really understand what I did. It is difficult to believe that I have won four consecutive titles", del Potro said, crediting coach Franco Davín for his impressive run. "He changed my game. He changed my mind. He changed everything. When I play and I see him in the stands, it gives me confidence. I can play relaxed."
At the 2008 US Open, del Potro progressed to the third round, where he won his first match to five sets in the circuit against Gilles Simon to reach the round of 16. He went on to defeat Japanese teenager Kei Nishikori in straight sets. In the quarterfinals, he was stopped by eventual finalist Murray, losing after almost four hours. The defeat came after 23 consecutive victories: the second-longest winning streak in 2008 and the longest winning streak by a player outside the top 10 in the last 20 years.
Del Potro was selected to play his first home-based Davis Cup tie, between Argentina and Russia. He won his first singles match against Davydenko in three sets. He also won the fifth and deciding match against Igor Andreev in straight sets, booking Argentina a place in the final.
At the AIG Japan Open Tennis Championships, he made the final by defeating 11th seed Jarkko Nieminen, top seed and defending champion Ferrer, and fourth seed Richard Gasquet. He was defeated by Tomá? Berdych in the final. At the Madrid Masters, he lost in the quarterfinals in straight sets to Roger Federer. He reached the semifinals of his next tournament, the Davidoff Swiss Indoors, before losing to countryman Nalbandian. He was beaten by Nalbandian again in his next tournament, this time it was in the second round of the Paris Masters. Del Potro blamed fatigue for his defeat, "It's difficult to play the last tournament of the year. I was tired, my mind was in Argentina [the venue for the Davis Cup final]". This left del Potro's qualification for the 2008 Tennis Masters Cup out of his hands, but Jo-Wilfried Tsonga beat James Blake in the semifinals, which was enough to ensure his place at the year-end event.
Del Potro won one match at the Masters Cup, against Tsonga, but lost his other two matches against the higher-ranked Djokovic and Davydenko, meaning that he exited the tournament in the round-robin stage. This was his last event of the year on the ATP Tour. He went on to lose one match in the Davis Cup final, against López, as his team succumbed to a 3-1 loss against Spain. He withdrew from his second match due to a thigh injury and was replaced by José Acasuso. Nonetheless, del Potro enjoyed a successful season; winning four titles and finishing 2008 as the youngest player in the top 10, top-ranked Argentine, and highest-ranked South American.
Del Potro began his 2009 season at the Heineken Open in Auckland, New Zealand, del Potro was the top seed. He defeated American Sam Querrey in the final to win the title, the fifth of his career. Seeded eighth at the Australian Open, he beat Marin ?ili? in the fourth round. Del Potro's tournament ended in his next match, when he lost in straight sets to Federer. At the BNP Paribas Open, the sixth seed del Potro advanced to the quarterfinals, where he was defeated by world No. 1 Nadal. Del Potro avenged that loss the following week at the Sony Ericsson Open, where he came back from a double break down in the third set at 0-3 to defeat Nadal in the quarterfinals. This was the first time del Potro had defeated Nadal in five meetings. Despite a loss in the semifinals to Murray, del Potro reached a career-high world ranking of No. 5.
In the clay-court season, del Potro was eliminated in the second round of the Monte Carlo Masters by Ivan Ljubi?i?. In Rome, del Potro beat Victor Troicki and Wawrinka to advance to the quarterfinals, where he was defeated by defending champion Djokovic in straight sets. This meant del Potro's head-to-head record with the Serb was now 0-3. Del Potro then played at the 2009 Madrid Masters. After defeating Murray for the first time in the quarterfinals, he lost to Federer in the semifinals. At the French Open, where he was fifth seed, del Potro defeated Michaël Llodra, Troicki, Andreev, and ninth seed Tsonga en route to the quarterfinals. He then defeated three-time former quarterfinalist Tommy Robredo to get to his first semifinal of a Grand Slam. He was defeated in a close semifinal, where he was leading by a set twice, by eventual champion Federer who, after their match, said: "[Del Potro] is young and strong, I have a lot of respect for him." Prior to this encounter, del Potro had never taken a set from Federer in their five previous career meetings.
At the 2009 Wimbledon Championships, his poor grass-court form from the past continued, as he went down to unseeded Lleyton Hewitt in the second round. In the Davis Cup quarter-final against the Czech Republic, del Potro won his matches against Ivo Miná? and Berdych in straight sets, but Argentina still lost the tie 2-3, eliminating them from the competition. A few weeks later, he defeated Hewitt and Fernando González en route to the Washington final. He successfully defended his title against top-seeded Wimbledon finalist Andy Roddick to win his second tournament of the year and become the first player since Andre Agassi to win back-to-back Washington titles. Del Potro played the following week at the Masters 1000 in Montreal, where he was seeded sixth, defeating world No. 2 Nadal in the quarterfinals, his second win in a row over Nadal. He then defeated Roddick in the semifinals, saving a match point, to advance to his first Masters 1000 final, and to improve his head-to-head record against Roddick to 3-0. In the final, he lost against Murray in three sets. He later withdrew from the next Masters 1000 event in Cincinnati due to fatigue.
Seeded sixth at the 2009 US Open, del Potro began by defeating Juan Mónaco and Jürgen Melzer in straight sets, before dropping a set but defeating Köllerer to reach the fourth round. He defeated a resurgent Juan Carlos Ferrero to advance to the quarterfinals for the second consecutive year. Del Potro then advanced to the semifinals by defeating Marin ?ili?. Del Potro was down a set and a break, before winning 17 of the final 20 games to win the match. His advance to the semifinals ensured his return to the top 5 in the rankings. He then easily defeated and crushed world No. 3 and reigning Australian Open champion Rafael Nadal in the semifinals to reach his first Grand Slam final. This was his third consecutive victory over Nadal and made him the first Argentine to reach a Grand Slam singles final since Mariano Puerta at the 2005 French Open. In the finals, del Potro rallied from a set and a break down to defeat world No. 1 and five-time defending champion Roger Federer in five sets; his first victory over Federer after six previous defeats, and Federer's first loss in the US Open since 2003. Del Potro stated, "Since [I was] young, I dream with this and take trophy with me", said del Potro, who became the first Argentine male to win the title since Guillermo Vilas in 1977. "I did my dream, and it's unbelievable moment. It's amazing match, amazing people. Everything is perfect." After the match, Federer praised del Potro; "I thought he hung in there and gave himself chances and, in the end, was the better man."
He is the first player since countryman David Nalbandian to defeat Federer at the US Open, and at 198 cm (6 ft 6 in), he is the tallest ever Grand Slam champion, a record he now shares with Marin ?ili?, the 2014 US Open winner. Besides Nadal and Djokovic, del Potro is the only player to defeat Federer in a Grand Slam final, and the first player to defeat both Nadal and Federer in the same Grand Slam tournament.
Dick Enberg hosted the post-match ceremony during which a victorious del Potro requested to address his fans in Spanish. Enberg declined the request saying that he was running out of time, but went on to list the corporate sponsored prizes del Potro won. A couple of minutes later, del Potro made the same request again, and only then did Enberg relent saying, "Very quickly, in Spanish, he wants to say hello to his friends here and in Argentina." An emotional del Potro finally spoke a few sentences in Spanish to a cheering crowd. Many viewers expressed disappointment with Enberg and broadcaster CBS over the interview. A CBS executive later defended Enberg, noting that the contract with the United States Tennis Association required that certain sponsors receive time during the ceremony.
In his first match since the US Open, del Potro was upset by world No. 189 Édouard Roger-Vasselin in straight sets at the Rakuten Japan Open Tennis Championships in Tokyo. He then lost his second straight match to Melzer in the second round at the Masters 1000 event in Shanghai, retiring while trailing in the second set. This retirement caused concerns over the length of the tennis season. He had to retire again in the Paris Masters quarterfinals when down 0-4 to Radek ?t?pánek due to an abdominal injury. In November, del Potro competed in the ATP World Tour Finals, where he lost his first round-robin match against Andy Murray, but he managed to defeat Fernando Verdasco in his second match to keep his hopes alive. After defeating Roger Federer in the following match, he qualified for the semifinals, ousting Murray by the slimmest possible margin of one game. He defeated Robin Söderling in the semifinals, before losing to Nikolay Davydenko in the final. Del Potro finished 2009 as the youngest player in the top 10, top-ranked Argentine, and highest-ranked South American for the second consecutive year.
Del Potro started his 2010 season at the AAMI Kooyong Classic in Melbourne, Australia with a win over Croatian world No. 24 Ivan Ljubi?i?. On 11 January, he moved up to a career high world No. 4. He was scheduled to face Frenchman Jo-Wilfried Tsonga on day 2 of the Kooyong Classic exhibition tournament, but withdrew due to a wrist injury. He came into the 2010 Australian Open with the injury not healed, and took a month off after the event. In the fourth round, he fell to eventual semifinalist Marin ?ili?.
Following the Australian Open loss, del Potro missed several tournaments, including the Masters tournaments at Indian Wells and Miami, which were touted as potential return dates, due to the persistent wrist injury. Even though he withdrew from the Monte-Carlo Rolex Masters, he regained the world No. 4 ranking, due to Murray's early exit in the second round. He then withdrew from Barcelona and the Rome Masters. On 4 May, del Potro took the option of having an operation to fix the injury. On 19 May, del Potro said he would not defend his US Open title, but if all went well, he would appear after the event, targeting the Paris Masters as a possible comeback. However, on 22 July, the USTA stated that del Potro was expected to defend his US Open crown. The player himself confirmed that his comeback to the tour would be the Thailand Open and said nothing about the New York event. On 2 August, del Potro returned to the practice courts. A week before the start of the US Open, after practicing for two weeks, del Potro withdrew from the event, as he felt he was not ready to compete at the highest level.
After the nine-month break, del Potro confirmed that he would make his return at the 2010 PTT Thailand Open. In his return match, he lost in the first round to Olivier Rochus. He then also played at the 2010 Rakuten Japan Open Tennis Championships, but again lost in the opening round, this time to Feliciano López.
Del Potro began his 2011 season at the Medibank International as a wildcard entry. In the second round, del Potro was defeated by Florian Mayer of Germany in straight sets, despite winning against sixth seed Feliciano López in three sets in the first round. His next tournament would be the first Grand Slam of the year at the 2011 Australian Open, where del Potro was defeated by 21st seed Marcos Baghdatis in the second round. As a result, del Potro slipped further down the rankings to No. 485.
After the Australian Open, he participated in the 2011 SAP Open in San Jose, where he was accepted into the main draw via protected ranking (PR). He reached the semifinals without dropping a set, however he lost to top seed Fernando Verdasco in straight sets. Del Potro's next scheduled tournament was the 2011 Regions Morgan Keegan Championships and the Cellular South Cup, where he was accepted into the main draw via wildcard. Here, he made his second consecutive ATP semifinal, where he lost to top seed, world No. 8, and eventual champion Andy Roddick. To continue preparing for his first ATP Masters event since 2009, del Potro entered the 2011 Delray Beach International Tennis Championships. He defeated Ri?ardas Berankis, Teymuraz Gabashvili, Kevin Anderson and second seed Mardy Fish, to advance to an ATP-level final stage of a tournament since 2009 at the Barclays World Tour Finals in London. In the final, he defeated an erratic Janko Tipsarevi? in two sets to get back in the winners circle.
Del Potro's next tournament was the ATP Masters at the 2011 BNP Paribas Open. He reached the semifinals, where he lost to top seeded Rafael Nadal in straight sets. Del Potro then flew to Key Biscayne, Miami to participate in the second ATP Masters of the year at the 2011 Sony Ericsson Open. Del Potro made it to the fourth round, in the third round he defeated world No. 4 Robin Söderling in straight sets, however in the next round he lost to eventual semifinalist Mardy Fish in straight sets.
He then played in 2011 Estoril Open, which was del Potro's first tournament on clay since he lost the 2009 Roland Garros semifinal to the eventual champion Roger Federer. In Estoril, he defeated Fernando Verdasco in the final. On the way to the final, del Potro defeated top seeded Robin Söderling (Who was two time-finalist in the French Open) and dropped just one set in his five matches. After suffering an 8-millimeter tear in his left rectus, del Potro withdrew from 2011 Mutua Madrid Open and did not participate in the 2011 Internazionali BNL d'Italia, but confirmed that he would play the French Open. Del Potro lost to Novak Djokovic in the third round.
Del Potro reached the round of 16 at Wimbledon for the first time by defeating Flavio Cipolla, Olivier Rochus, and Gilles Simon. He then lost to world No. 1 Rafael Nadal, in four sets, in the fourth round. Del Potro returned to the top 20 at world No. 19 for the first time in nearly a year. His next tournament was the Farmers Classic in Los Angeles, where he received a first-round bye as the second seed. He defeated James Blake but was defeated by Ernests Gulbis in the quarterfinals.
At the 2011 Rogers Cup, seeded 16th, del Potro defeated Jarkko Nieminen before losing to Marin ?ili? in the second round. At the Western & Southern Masters tournament, del Potro lost to Roger Federer, snapping the two-match winning streak he had against his rival. Del Potro entered the 2011 US Open seeded 18th. He beat Filippo Volandri and Diego Junqueira before losing to Gilles Simon in the third round, thus ending his US Open campaign.
After the US Open, del Potro played in the Davis Cup semifinal against Serbia, winning both of his rubbers against Janko Tipsarevi? and world No. 1 Novak Djokovic. This helped Argentina to a 3-2 victory over Serbia in the semifinals, booking their place in the final. He then played in the Stockholm Open, losing in the second round to James Blake. He then reached the final in Vienna, losing for the first time to Jo-Wilfried Tsonga. Despite having won the first set, he eventually lost the final. Del Potro then reached the semifinals of the Valencia Open 500, losing to eventual champion Marcel Granollers. He then withdrew from the Paris Masters due to a shoulder injury, wiping out his chances of qualifying for the Year-End Championships.
Del Potro played in the Davis Cup Final, with the title on the line and looking to fulfill his childhood dream. He lost in the second rubber to David Ferrer, despite being two sets to one up, eventually losing in a pulsating five-set contest in a match lasting over five hours. With his country down 2-1, del Potro needed to beat Rafael Nadal in the reverse singles to keep the tie going.

Del Potro decided to skip the Australian Open and made his season debut at the Delray Beach Open, where he was seeded in a tournament for the first time in three years, at No. 7, and won his first three matches against Kevin Anderson, Damir Dzumhur and Sam Querrey, who beat him in the semifinals of the same tournament last year. However, in the semifinals this year, del Potro lost to top seed and world No. 4 Milos Raonic in straight sets.

The US Open account on Instagram switched his racquet for Thor's hammer using software editing tools, which created a new nickname for the Argentine: Juan Martin "del Thortro", by fellow tennis player Roger Federer, adding to a collection of nicknames such as "Delpo", "Tower of Tandil", "Palito" (stick) and "Enano" (midget). This led to a joke in social media with Chris Hemsworth, who plays Thor, and in this joke he demands his hammer back because he claimed to need it for his quests.
In the quarterfinals he defeated Roger Federer in four tight sets; his second victory over the Swiss at the US Open, having beaten him in the final in 2009. By doing so he reached his first major semifinal since Wimbledon 2013. His run came to an end in 4 sets, losing to World No. 1 Rafael Nadal.
Del Potro began his Asian hard court swing in Beijing, where he lost in straight sets Grigor Dimitrov in the second round, his second loss against the Bulgarian.

However, he was defeated in three sets by John Isner and subsequently declined to be chosen as an alternate for the tournament, instead choosing to rest with his family and friends in his native Tandil.

In his first grass tournament of the season, the Queen's Club Championship, del Potro suffered another career-threatening injury when he fractured his kneecap in his first round match against Denis Shapovalov
Del Potro is an offensive baseliner with a very powerful serve and deep, flat, topspin groundstroke, where he pushes his opponents deeper with his heavy groundstroke and trying to blast past them with a winner. His forehand is one of his main strengths and possibly the most powerful in the game, capable of frequently generating speeds more than 160 km/h. It is widely considered among the top three best forehands on tour by fellow players and analysts, alongside Roger Federer and Rafael Nadal.
Although he possessed a very consistent and powerful double-handed backhand, injury and surgeries on his wrist have rendered his backhand the main weakness in his game. Since his return in 2016, del Potro made tactical changes in his game in order to protect his wrist, like significantly reducing the pace of his two-hander and adopting a one-handed slice. Despite del Potro admitting that relying on slices is "not my game," the shot has been effective in moving his opponents out of position and slowing down rallies enough to allow him to set up powerful offensive shots with his forehand. Furthermore, to compensate for the newfound vulnerability in his backhand wing, del Potro has improved the power and accuracy of his other shots, most notably his serve.
Del Potro used the Wilson Hyper ProStaff 6.1 Midplus Stretch early on in his career, and has continued to use this racquet under new paint jobs years later. Del Potro is very superstitious, and after suffering a wrist injury shortly after switching to the Wilson BLX Pro Tour paint job in 2010, he returned to playing with the then outdated Wilson K-Factor 6.1 95 paint job. He particularly favored the exact racquets he had used to win his only Grand Slam title at the 2009 US Open. He again refused to update his racquet to the Wilson BLX Juice Pro in 2012, and in 2014 had only a few K-Factor racquets left. For strings, he uses Luxilon ALU Power strung at 58 lbs. He currently makes use of the Wilson ProStaff 97.
His clothing sponsor is Nike. He used to wear sleeveless shirts, but more recently has worn crew shirts, and often also sports double-wide wristbands and a bandana. For shoes, he wears Nike Air Max Cages. He used to choose his own outfits but somewhere between 2014 and 2015 he started to use the brand's shirts for every player, losing the ability of choosing what he wanted to wear.
Del Potro has a combined 20-51 (28.2%) record against all members of the Big Four, which is one of the best in this category. He is also one of the few to have won at least three matches against each of the four.
Del Potro has a 7-18 (28.0%) record against Roger Federer. They have met in 6 finals, all at ATP World Tour 500 Series level or higher, with del Potro leading 4-2; besides the US Open title he also captured both 2012 and 2013 Swiss Indoors finals against the seven-time champion of the tournament and the 2018 Indian Wells final, while Federer has won finals against del Potro at the 2012 Rotterdam Open and the 2017 Basel Open. Del Potro also won their biggest match to date in 5 sets at the 2009 US Open final, shortly after Federer won their next most important match in 5 sets at the 2009 French Open semifinals a few months before. Federer also won the longest best of 3-set match in the history at the 2012 Olympic semifinal against del Potro, 19-17 in the deciding set. Del Potro also prevailed in 2017 US Open quarterfinals against Federer in 4 sets. Federer prevailed in three sets in the 2017 Basel final. However, at their most recent meeting at Indian Wells Masters in 2018, Del Potro won in the finals, winning his first Masters 1000.
Del Potro has a 4-16 (20.0%) record against Novak Djokovic. Djokovic won their first four meetings, before back to back victories for del Potro at the 2011 Davis Cup and their Bronze medal match at the 2012 Summer Olympics in straight sets. However, in 2013, Djokovic got the upper hand on the rivalry again and won two of the most important matches between them to date; an epic five-setter at the 2013 Wimbledon Championships semifinals and a thrilling three-setter at the 2013 Shanghai Masters final. In the same year, del Potro defeated Djokovic en route to his second Masters 1000 final, at the 2013 Indian Wells Masters, where he lost to Nadal. Del Potro upset Djokovic in the first round at the 2016 Olympics in Rio en route to the final, where he lost to Murray. Djokovic defeated Del Potro in three close sets in the final of the 2018 US Open, which was the first grand slam final for Del Potro since his victory at the 2009 US Open. Three of his four victories have come via national representation tournaments.
Del Potro has a 6-11 (35.3%) record against Rafael Nadal. Del Potro bested Nadal in the semifinals en route to his 2009 US Open title which was the first time a player managed to beat both Roger Federer and Nadal in the same Grand Slam tournament (Novak Djokovic did this at the US Open 2011). However the Spaniard managed to win both times in the Indian Wells Masters encounters, in the 2011 semifinal and the 2013 final. Nadal also won the fourth and last rubber of the 2011 Davis Cup final against the Argentine. Del Potro gained the upper hand at the 2013 Shanghai Masters, defeating Nadal to reach the final where he lost to Djokovic.
