Garbiñe Muguruza Blanco (Spanish pronunciation: [?a?'?i?e mu?u'?u?a '?la?ko];[a] born 8 October 1993) is a Spanish-Venezuelan tennis player and former world No. 1. Since turning professional in 2012, she has won seven singles titles, including two grand slams, the 2016 French Open and the 2017 Wimbledon Championships.
Equipped with powerful groundstrokes and an aggressive style of play, Muguruza came to prominence in 2014 after reaching the last 16 at the Australian Open, beating former world No. 1 Caroline Wozniacki en route. She then defeated then world No. 1 Serena Williams in the second round of the French Open, beating her in straight sets in Williams' most lopsided loss at a Grand Slam, and reaching the quarterfinals.
In 2015, at the Wimbledon Championships, she made it to her first Grand Slam final where she lost to Serena Williams, and then won her maiden Premier-level crown by capturing the China Open title. The same year, she qualified for her first WTA Finals in singles, scoring a perfect winning record in the round-robin stage before losing to eventual champion Agnieszka Radwa?ska in the semi-finals.
Muguruza has been successful in doubles, winning five titles, finishing runner-up at the 2015 WTA Finals and reaching the 2014 French Open semifinals. She achieved those results with her compatriot Carla Suárez Navarro.
Garbiñe Muguruza was born in Caracas, Venezuela, on 8 October 1993 to Venezuelan mother, Scarlet Blanco and Basque father José Antonio Muguruza. She has two elder brothers named Asier and Igor, and has dual Spanish-Venezuelan nationality. Muguruza began playing tennis at the age of three. After moving to Spain with her family when she was six years old, Muguruza began training at the Bruguera Tennis Academy near Barcelona. Muguruza occasionally plays the guitar in her free time.
Muguruza is known for her flat, powerful groundstrokes from both wings. They allow her to take time away from her opponents and dictate baseline rallies, despite the fact that Muguruza may often refrain from going for the lines, or outright winners. She also possesses a powerful serve that is capable of reaching speeds of up to 113 mph (182 km/h). Fellow tennis player Agnieszka Radwa?ska describes Muguruza's playing style as being "very explosive, especially from every shot. So forehand, backhand, serve, return, everything is coming to you so fast."
Her ability to move and slide effectively on clay leaves her noted for her clay-court prowess, having reached three consecutive quarterfinals at Roland Garros from 2014 to 2016. Muguruza has said that "clay is [her] territory", as she feels most comfortable on the surface. However, as a result of her high-risk game style, her inconsistency is discussed in the tennis community. Her game can lend itself to several unforced errors and double faults in any given match, and she often loses matches to players ranked several places below her. She had been coached by Alejo Mancisidor from 2010 to 2015, but then hired Sam Sumyk in 2015. Since then, Muguruza has attempted to finish more points off at the net, which has seen mixed results. Muguruza split from Sumyk in 2019, and began working again with Conchita Martínez that November. Martinez previously coached Muguruza at Wimbledon 2017, where she won the title. After working with Martínez, Muguruza became more selective when choosing to approach the net, and improved her net game significantly - in her 2020 Australian Open match against Elina Svitolina, Muguruza made 16 net approaches, and won 14 of these net points.
After she turned pro on 2 March 2012, Muguruza was given a wildcard at the Miami Open for her first WTA main draw appearance. There, she upset former world No. 2, Vera Zvonareva, and former world No. 10, Flavia Pennetta, before falling in the round of 16 to the eventual champion Agnieszka Radwa?ska in straight sets.
At the 2013 Australian Open, Muguruza made it into the main draw after several players withdrew that did not pass into the qualifying match, she lost to Serena Williams in straight sets in the second round.
At the 2013 BNP Paribas Open, Muguruza qualified for the main draw and then made her way to the last 16, where she fell to eventual semi-finalist Angelique Kerber. She was then awarded a main draw wildcard into the Miami Open once more where she matched last year's result, recording wins over Kate?ina Siniaková, 23rd seed Anastasia Pavlyuchenkova and ninth seed Caroline Wozniacki en route to the round of 16 where she lost to fifth seed Li Na.
After the Wimbledon Championships, Muguruza underwent a right ankle surgery and missed the rest of the season. She continued to train by hitting groundstrokes sitting down. She ended that year as the world No. 63 in singles and No. 153 in doubles.
Muguruza began the 2014 season with a quarterfinal appearance at the Auckland Open, where she lost to former world No. 1 and eventual runner-up, Venus Williams. The following week, Muguruza qualified and eventually won her first WTA singles title at the Hobart International by defeating Klára Zakopalová in the final in straight sets.
At the Australian Open, Muguruza recovered from a set down to defeat 10th seed Caroline Wozniacki in three sets to reach the fourth round for the first time where she lost in straight sets to the fifth seed, Agnieszka Radwa?ska. She and Arantxa Parra Santonja also reached the second round of the doubles event where they lost in straight sets to the 8th seeds, Raquel Kops-Jones and Abigail Spears.
After a three-set defeat to Kimiko Date-Krumm in the first round of the Thailand Open, Muguruza reached her second singles final of the year at the Brasil Tennis Cup, where she lost in three sets to Klára Zakopalová despite having led by a set and 5-2. Muguruza then lost in the second round of the Indian Wells Masters and Miami Open after receiving opening round byes, but did reach the quarterfinals of the latter event in doubles where she and her partner, Carla Suárez Navarro lost in three sets to the 8th seeds, Raquel Kops-Jones and Abigail Spears.
Muguruza recovered from her first round defeat at the Monterrey Open by reaching the semifinals of the Marrakech Grand Prix where she lost to the eventual champion, María Teresa Torró Flor in straight sets. However, she and Romina Oprandi managed to win the doubles event by defeating Katarzyna Piter and Maryna Zanevska in the final in three sets. At the Madrid Open, Muguruza lost in the second round to former US Open champion, Samantha Stosur but reached the final of the doubles event with Carla Suárez Navarro where they lost in straight sets to the second seeded Italians, Sara Errani and Roberta Vinci.
After a second round defeat to former French Open champion Francesca Schiavone at the Italian Open, Muguruza advanced to her first major quarterfinal at the French Open, having handed the world No. 1 and defending champion Serena Williams her worst defeat in a major tournament, losing only four games in the second round, before losing to the eventual champion, Maria Sharapova in three sets. Muguruza also reached the semi-finals of the doubles event with Suárez Navarro, where the pair lost in three sets to the top seeds and eventual champions, Peng Shuai and Hsieh Su-wei. As a result of her strong performances at the event, Muguruza achieved career high singles and doubles rankings of world No. 27 and No. 36 respectively.
Muguruza began her grass court season at the Rosmalen Grass Court Championships where she reached the quarterfinals before losing to American qualifier CoCo Vandeweghe in straight sets after leading 5-2 in the opening set. At the Wimbledon Championships, Muguruza was seeded twenty-seventh but was upset by Vandeweghe in the first round in three sets. Seeded sixteenth in the doubles event with Carla Suárez Navarro, Muguruza and her partner defeated Ajla Tomljanovi? and Christina McHale and Monica Niculescu and Klára Koukalová to reach the third round where they lost in straight sets to Andrea Petkovic and Magdaléna Rybáriková.
Muguruza began the North American hard court season at the Stanford Classic. She defeated sixth seed and defending champion, Dominika Cibulková, in three sets and unseeded Slovakian Daniela Hantuchová to reach the quarterfinals where she lost in straight sets to the third seed Angelique Kerber. Seeded third in the doubles event with Carla Suárez Navarro, the pair defeated Eva Hrdinová and Andreja Klepa?, Caroline Garcia and Zhang Shuai and the second seeds, Anastasia Rodionova and Alla Kudryavtseva to reach the final where they defeated Paula Kania and Kate?ina Siniaková in three sets to win the title. At the following week's Canadian Open, Muguruza overcame Canadian qualifier Stéphanie Dubois in the first round before falling in three sets to fourth seed, Maria Sharapova. In the doubles event, Muguruza and Suárez Navarro progressed to the second round where they lost to the second seeds, Hsieh Su-wei and Peng Shuai. At the Cincinnati Masters, Muguruza lost in the first round to German qualifier Annika Beck but reached the quarterfinals in doubles where she and Suárez Navarro lost to Kimiko Date-Krumm and Andrea Hlavá?ková in straight sets. At the Connecticut Open, Muguruza upset seventh seed Sara Errani before defeating qualifier Peng Shuai to reach the quarterfinals where she lost in three sets to unseeded Italian, Camila Giorgi. She and Suárez Navarro also lost to Marina Erakovic and Arantxa Parra Santonja in the first round of the doubles event. Muguruza's next event was the US Open, where she competed as the 25th seed. However, she was upset by resurgent qualifier, Mirjana Lu?i?-Baroni in the first round in straight sets. She and Suarez Navarro also reached the third round of the doubles event, defeating Alizé Cornet and Kirsten Flipkens and Marina Erakovic and Arantxa Parra Santonja en route before losing to the unseeded Williams sisters.
Muguruza began the Asian swing by competing at the Pan Pacific Open. She defeated Anastasia Pavlyuchenkova, 4th seed Jelena Jankovi? and Casey Dellacqua en route to the semi-finals where she fell in three sets to the second seed and eventual runner-up, Caroline Wozniacki. Muguruza also reached the final of the doubles event with Carla Suárez Navarro, defeating Pavlyuchenkova and Lucie ?afá?ová, Jarmila Gajdo?ová and Arina Rodionova and the second seeds, Raquel Kops-Jones and Abigail Spears en route before losing to the top seeds, Cara Black and Sania Mirza in straight sets. Muguruza next competed at the inaugural edition of the Wuhan Open, where she reached the third round of the singles, defeating María Teresa Torró Flor and world No. 2 Simona Halep en route and the second round of the doubles with Suárez Navarro after defeating Torró Flor and Sílvia Soler Espinosa in the first round but was ultimately forced to withdraw from the event due to gastritis. At the following week's China Open, Muguruza suffered a three set first round loss to Ekaterina Makarova but reached the quarterfinals of the doubles event with Suárez Navarro.
Muguruza's final event of the year was the season ending Tournament of Champions in Sofia, Bulgaria. Despite going undefeated in the round robin stage with wins over top seed, Ekaterina Makarova, third seed Flavia Pennetta and 6th seed Alizé Cornet Muguruza fell to the eventual champion, Andrea Petkovic in the semifinals in straight sets. Muguruza finished the year ranked at career high rankings of world No. 21 in singles and No. 16 in doubles.
Muguruza's first event of the year was to be the Brisbane International but she was forced to withdraw from the event due to an ankle injury. The following week, Muguruza chose not to defend her title at the Hobart International and competed at the Sydney International instead, where she reached the quarterfinals, defeating Agnieszka Radwa?ska for the first time in her career en route. At the Australian Open, she progressed to the fourth round for the second consecutive year with wins over Marina Erakovic, Daniela Hantuchová and Timea Bacsinszky before falling to the eventual champion, Serena Williams, in three sets.
Muguruza won both of her singles rubbers in the 2015 Fed Cup World Group II, defeating Irina-Camelia Begu and world No. 3, Simona Halep but Spain, lost the tie 2-3 after Muguruza and her compatriot, Anabel Medina Garrigues, lost the deciding doubles rubber. At the Dubai Tennis Championships, Muguruza reached her first Premier-5 semifinal in singles, defeating qualifier Jarmila Gajdo?ová, twelfth seed Jelena Jankovi?, fifth seed Agnieszka Radwa?ska and 13th seed and doubles partner Carla Suárez Navarro before falling to the seventeenth seed and eventual runner-up, Karolína Plí?ková in three sets. She also reached the final of the doubles with Suárez Navarro. The following week, Muguruza retired from her first round match against Suárez Navarro at the Qatar Open while trailing 6-5 in the first set.
In March, Muguruza lost to Karolina Plí?ková in the third round of the Indian Wells Masters after a second-round win over American wildcard Irina Falconi. Despite this, she rose to a career high singles ranking of world No. 19 after the event. A fortnight later, Muguruza reached the third round of the Miami Open after defeating qualifier Sesil Karatantcheva but lost to the 11th seed Sara Errani after winning the first set.
Muguruza reached the second round of the three clay court events that she competed in leading into the French Open. She lost to second seed Simona Halep in Stuttgart, Kristina Mladenovic in Marrakech and the eventual finalist Svetlana Kuznetsova in Madrid. Muguruza and Suárez Navarro also reached the doubles final of the latter for the second consecutive year but the pair lost in three sets to Casey Dellacqua and Yaroslava Shvedova. Despite failing to win back-to-back matches since February, Muguruza reached her second consecutive French Open quarterfinal, defeating Angelique Kerber and Flavia Pennetta en route, before losing to the eventual runner-up, Lucie ?afá?ová.
Muguruza made a poor start to the grass court season, losing in the first round of the Birmingham Classic and the third round of the Eastbourne International after a first round bye. However, she and Suárez Navarro won their first grass court doubles title in Birmingham, defeating Andrea Hlavá?ková and Lucie Hradecká in straight sets in the final. At the Wimbledon Championships, Muguruza defeated 10th seed Kerber in the third round, 5th seed Caroline Wozniacki in the fourth round, 15th seed Timea Bacsinszky in the quarterfinals and 13th seed Agnieszka Radwa?ska in the semifinals to advance to her maiden major final. She played against world No. 1, Serena Williams, for the title, but lost in straight sets. After the tournament, Muguruza entered the top 10 for the first time, moving up to world No. 9 in the rankings.
During the US Open series, Muguruza did not enjoy much success, dropping her opening matches in Toronto and Cincinnati to qualifiers Lesia Tsurenko and Yaroslava Shvedova respectively. At the US Open, she recorded her first win at the tournament by defeating German Carina Witthöft in the first round. However, she fell short to Johanna Konta in the following round in three sets, the match was a total time of 3 hours and 23 minutes, the longest women's singles match in that tournament's history since the introduction of tiebreaker in 1970.
Muguruza kicked off the Asian swing at the Pan Pacific Open where she advanced to the last eight after defeating Barbora Strýcová before losing to eventual finalist Belinda Bencic in straight sets. At the Wuhan Open, Muguruza cruised into her second straight quarterfinal at the event after dispatching Sloane Stephens and Ana Ivanovic. She then went on to defeat the likes of Anna Karolina Schmiedlova and Kerber to reach the final where she faced Venus Williams but was forced to retire in the second set with an ankle injury. Muguruza was able to crack the Top 5 for the first time in her career after the tournament's conclusion. At the China Open, Muguruza breezed by Irina Falconi before going the distance against Mirjana Lu?i?-Baroni to advance to the quarterfinals. With the win, Muguruza qualified for the WTA Finals for the first time. She will be the first Spaniard to compete at the year-end championships since Arantxa Sánchez Vicario in 2001. She then beat Bethanie Mattek-Sands and Radwa?ska to advance to her maiden Premier Mandatory final. With her semifinal win over Radwa?ska, Muguruza reached a career high of world No. 4. She went on to defeat Bacsinszky in straight sets to claim her first Premier Mandatory title and her biggest title of her career.
Muguruza then traveled to Singapore for the WTA Finals, where she went undefeated in the round robin play, beating Petra Kvitová, Angelique Kerber, and Lucie ?afá?ová. She then lost to eventual champion Agnieszka Radwa?ska in the semifinals. Muguruza also competed in doubles in Singapore, where she and her compatriot Carla Suárez Navarro reached the final. However, they lost to the No. 1 seeds Martina Hingis and Sania Mirza.
Muguruza started her year at Brisbane International, when she already had to retire in her first match of the tournament due to plantar fasciitis. Her next tournament was the Australian Open, where she ensured a spot in the third round with straight set wins over Anett Kontaveit and Kirsten Flipkens, but fell to Barbora Strýcová. At the Fed Cup, Muguruza helped in Spain's tie against Serbia with wins over Ivana Jorovi? and Jelena Jankovi?.
At the Dubai Tennis Championships, Muguruza suffered another early loss as she fell to eventual semi-finalist Elina Svitolina. Her next tournament was the Qatar Open, where she reached first quarterfinal of the year, defeating Nao Hibino and Tímea Babos, but lost then to Andrea Petkovic in three sets. Next she played in Indian Wells Open, where she lost in her opening match against Christina McHale after receiving first round bye. At the Miami Open, she was close to being defeated in the opening match against Dominika Cibulkova but survived in the final set. She reached the fourth round but lost to the Indian Wells and eventual champion Victoria Azarenka in two tiebreakers.
She kicked off the clay court season by participating the Fed Cup against Italy. She scored wins against Francesca Schiavone and No. 7, Roberta Vinci, to help Spain enter the World Group next year. She then played in Stuttgart Open. She reached her second quarterfinals of the season where she lost to Petra Kvitová. At the Madrid Open, she lost in the second round against Irina-Camelia Begu, despite serving for the match. She then went on to reach her first WTA semifinals of the season in Rome, after defeating top ten opponent Timea Bacsinszky in quarterfinals, but lost to Madison Keys in straight sets.
At the French Open, Muguruza turned her season around, unexpectedly capturing her first major title. She lost the first set against Anna Karolina Schmiedlova in her first round match but won in three sets. After that she easily reached her second major final without losing a set in the next five matches, including wins over former champion Svetlana Kuznetsova in the fourth round, surprise quarterfinalist Shelby Rogers, and former runner-up Sam Stosur in the semi-finals. In the final, she faced world No. 1, Serena Williams, in a rematch of the previous year's Wimbledon final, and won in straight sets for her maiden major title. She marked 14 straight sets won after losing the first she played. With the title she rose to a career high No. 2 in the WTA rankings of 6 June 2016. She is also the first Spanish female player to win a major title since Arantxa Sánchez Vicario in 1998. By winning, Muguruza became the second player of either gender born in the 1990s to win a Major title after Petra Kvitová first did so at the 2011 Wimbledon Championships.
Muguruza started off the grass season by playing in her home tournament the Mallorca Open, where she was the No. 1 seed. However, she suffered a first-round exit to former Wimbledon semifinalist Kirsten Flipkens in straight sets, marking the third tournament of the year where she lost in her first match played and her second consecutive loss to Flipkens on grass. Muguruza returned to grass for Wimbledon as the second favorite with the chance to usurp the top ranking from Williams while being heralded as the leader of the next generation, following Williams' recent slump in tournament finals. Though Muguruza won her opening match against Camila Giorgi in a high quality display, she was quickly upset by Jana ?epelová in the second round. Unable to defend her finalist points from the previous year, Muguruza regressed to world No. 3 at the end of the tournament. At the Rio Olympic Games, Muguruza arrived as one of the favorite players to win in the women's singles tennis event. She defeated Andreea Mitu of Romania and Nao Hibino of Japan to progress to the third round. However, she was defeated comprehensively by the eventual Gold medalist Monica Puig of Puerto Rico.
Muguruza did not have much success during the US Open series, either. At the US Open, she suffered another second-round loss, this time to Anastasija Sevastova. She did not fare well during the Asian Swing, with early round losses at the Pan Pacific Open in Tokyo, the Wuhan Open in Wuhan, and the China Open in Beijing. The loss in Beijing was significant, because Muguruza was the defending champion, and she therefore dropped in ranking after the tournament. However, she still qualified for the WTA Finals. Muguruza was defeated in the round robin stage, her only win coming from a three-set match against Svetlana Kuznetsova. She ended the season ranked No. 7.
Muguruza started the season at the Brisbane International, being the No. 4 seed. She made a run to the semifinals after three-set wins over Sam Stosur and Daria Kasatkina, and a straight sets win over Svetlana Kuznetsova. She then retired in the first set of her semifinal match against Alizé Cornet due to injury. At the Australian Open, Muguruza beat Marina Erakovic, Samantha Crawford, Anastasija Sevastova and Sorana Cîrstea en route to her first quarterfinal at the tournament. She then lost to CoCo Vandeweghe in straight sets.
Muguruza then played the Fed Cup quarterfinals, where she beat Barbora Strycova in three sets before losing to Karolina Pliskova. Spain ended up losing the tie 2-3. During the Gulf Swing, she beat Ça?la Büyükakçay in Doha, before succumbing to Zhang Shuai in three sets. She then retired in her first match at Dubai against Kateryna Bondarenko, due to injury. At Indian Wells, Muguruza advanced to the quarterfinals, beating Kirsten Flipkens, 17-year-old Kayla Day, and Elina Svitolina en route. She then lost to world No. 3, Karolina Pliskova, in two tiebreaks. At Miami, she reached the fourth round and retired against Caroline Wozniacki after losing the first set due to illness.
Muguruza suffered early losses at the start of the clay season, losing in her opening matches in Stuttgart and Madrid to Anett Kontaveit and Timea Bacsinszky respectively. She bounced back in Rome by reaching the semifinals, before she had to retire against Elina Svitolina in the first set due to a neck injury. Muguruza entered the French Open as the defending champion, where she reached the fourth round, losing to home favourite Kristina Mladenovic in three sets. In that game against Mladenovic, Muguruza had to face an extremely unfavorable crowd as well, almost bordering on unsportmanship-like behavior, since most of her unforced errors were celebrated not only by Mladenovic but by the crowd too. As she left the court and was receiving an ovation from the crowd, she was seen shaking her head and demanding the crowd not to applaud, since they wanted her to lose. In the following press conference, when asked about the pressure she suffered from the crowd, she started to cry and had to quit the press conference for about five minutes before she came to resume her thoughts on the match. This prompted a huge reaction in the Spanish sporting press, with some making the comment that "The Suzanne Lenglen Court looked more like the Stade de France, and it was as if there was a football game going on and not a tennis match". Since she failed to defend her title, Muguruza fell from the top 10.
Prior to Wimbledon, Muguruza began her grass court season at the Birmingham Classic where she beat Elizaveta Kulichkova, Alison Riske and CoCo Vandeweghe before losing in the semi-finals to eventual runner-up Ashleigh Barty. She followed that with a second round exit at the Eastbourne International, losing to Barbora Strýcová.
As the 14th seed, Muguruza reached the Wimbledon fourth round, beating Ekaterina Alexandrova, Yanina Wickmayer and Sorana Cîrstea. She then faced the previous year's runner-up and world No. 1, Angelique Kerber, eventually beating her in three sets. She then defeated 7th seed Svetlana Kuznetsova and then 87th-ranked Magdaléna Rybáriková, both in straight sets, to advance to her second Wimbledon final. There, she defeated 10th seed Venus Williams in straight sets, clinching her second major title, and became the first ever player to defeat both Williams sisters in major singles finals.
Muguruza started her hard court summer in Stanford, beating Kayla Day and Ana Konjuh before losing in the semifinals to Madison Keys. She next travelled to Toronto for the Rogers Cup, and recorded wins over Kirsten Flipkens and Ashleigh Barty. Muguruza lost in the quarterfinals to Elina Svitolina. Muguruza's next tournament was the Western and Southern Open in Cincinnati. She won two tough three set matches against Madison Keys and Svetlana Kuznetsova to make it to the semifinals. There she faced Karolína Plí?ková, the world No. 1, to whom she had lost six times in a row. This time Muguruza turned the tables and won in two sets. In the final she played Simona Halep, dropping only one game in 57 minutes to capture the fifth title of her career. This also marked the first time in which she won multiple titles in one season.
Muguruza entered the US Open as a contender for the No. 1 WTA rankings. She beat Rybáriková in a rematch of the Wimbledon semifinal to reach the fourth round of the US Open for the first time, where she lost to Petra Kvitová in straight sets. Despite the loss, Muguruza rose to the No. 1 ranking after reigning No. 1 Karolína Plí?ková's loss to CoCo Vandeweghe in the quarterfinals, and became the 24th woman to achieve the ranking. Muguruza and Rafael Nadal made Spain the first country since the United States 14 years ago to simultaneously top both the ATP and the WTA rankings.
In Tokyo she lost to Caroline Wozniacki in the semifinals, winning only two games. She then lost in the quarterfinals of the Wuhan Open to Je?ena Ostapenko and retired in the first round of the China Open to Barbora Strýcová after losing eight of the first nine games. With Simona Halep advancing to the final of the event, Muguruza ultimately lost the No. 1 ranking. Shortly after, she was named WTA Player of the Year. Muguruza was seeded second at the WTA Finals and was drawn in the red group alongside Karolína Plí?ková, Venus Williams and Je?ena Ostapenko. She won her first match against Ostapenko in straight sets before losing to Plí?kova, winning two games in both sets. Muguruza then faced Williams for a place in the semifinals but ended up losing in straight sets. This loss ended Muguruza's chances of gaining the year-end No. 1 ranking.
Muguruza started the season at the Brisbane International, where she was the top seed. After receiving a bye into the second round, she faced Aleksandra Kruni?, but was forced to retire due to cramping in the third set. Muguruza had served for the match in the second set, and the retirement marked the third straight year she had succumbed to injuries at Brisbane. Muguruza then took a wild card into the Sydney International, where she was once again the top seed. After beating Kiki Bertens in the second round, Muguruza withdrew from the tournament due to continued physical problems.
At the Australian Open, Muguruza was the third seed, and was also in contention for the No. 1 ranking. In the first round, she beat French wildcard Jessika Ponchet in straight sets. In the second round, Muguruza was shocked by the world No. 88 Hsieh Su-wei in straight sets.
After losing early at the Australian Open, Muguruza announced that Conchita Martínez would be rejoining her team for the next four events. In her first event back with Martínez, Garbiñe reached the Qatar Open final, recording wins over Duan Yingying, Sorana Cirstea, and Caroline Garcia en route. She then lost to Petra Kvitová in three sets. Muguruza then played Dubai, where she was seeded second. After receiving a first round bye, she beat CiCi Bellis and Caroline Garcia in straight sets. In the semifinals, Muguruza lost to Daria Kasatkina in three sets, despite having served for the match and held three match points in the second set.
Her next tournament was Indian Wells. In the second round, she played Sachia Vickery, ranked No. 100 in the world. Muguruza led by a set and a double break, but eventually succumbed in three sets. At the Miami Open, she reached the fourth round where she lost to eventual champion Sloane Stephens. The end of the tournament also marked the completion of Muguruza's temporary partnership with Martínez. Later that spring, she won the championship in Monterrey, Mexico, coming back from a set and a break down to defeat Timea Babos in three sets in the final. The victory marked Muguruza's first title win since the 2017 Western & Southern Open.
After Monterrey, her clay-court season began with the Fed Cup World Group II Play-offs, where Spain was to face Paraguay. In her first match, Muguruza faced world No. 334 Montserrat González, winning in three close sets. Muguruza had served for the match in the second set and held a match point, but was forced into a decider. Muguruza's next singles match was against Verónica Cepede Royg, which she won in straight sets. The victory ensured Spain would remain in World Group II next season. Her next tournament was Stuttgart, where she was the No. 2 seed. In her first match against Anastasia Pavlyuchenkova, Muguruza retired after the first set because of a back injury. She then played in Madrid where she lost in third round to Daria Kasatkina. In Rome, Muguruza had bye in first round and in second round she lost to Daria Gavrilova.
At Wimbledon, defending champion Muguruza was eliminated in the second round by Belgian world No. 47 Alison Van Uytvanck, and thus suffered the earliest defeat of a defending women's champion at the All England Club since Steffi Graf lost in the first round in 1994
Muguruza finished her 2018 season with her ranking at a low of 18.
On 15 August 2018, Hopman Cup organizers announced that Muguruza will represent Spain at the 2019 edition alongside David Ferrer. At her first appearance at the tournament, she lost to Angelique Kerber of Germany in three sets.
Muguruza's struggles at the majors would continue at Wimbledon, losing to Beatriz Haddad Maia in the first round. Following the loss, Muguruza announced a split with her longtime coach Sam Sumyk. She would also go on to lose in the first round of the US Open that year.
Muguruza began the 2020 season with a semifinal appearance in Shenzhen, losing to eventual champion Ekaterina Alexandrova. After pulling out of her quarterfinal match in Hobart due to illness, she bounced back at the Australian Open, beating four seeded players, including 5th seed Elina Svitolina, 4th seed Simona Halep and 9th seed Kiki Bertens to reach her fourth Grand Slam final, and first ever final in Melbourne. She lost to 14th seed Sofia Kenin in 3 sets in the final.
Muguruza was named the ambassador for Mazda Spain in June 2014 and for BBVA bank in December 2014. Her other endorsement partners are Adidas, Babolat, Rolex and Maui Jim. In June 2016, she was named the 14th most marketable athlete by SportsPro.
