Liukko began playing Davis Cup tennis for the Finnish team in 1994. By the time he made his last appearance in 2001, he had taken part in 15 ties. He won 19 of his 34 rubbers, 12 in singles and seven in doubles. His doubles partnership with Tuomas Ketola is the most successful in Finland Davis Cup history, securing six wins.
The Finn made it through qualifying at the 1999 US Open and faced Goran Ivani?evi? in the first round. He was beaten in four sets. In the Tashkent President's Cup later that year he defeated Marat Safin, then ranked 35th in the world. Safin retired hurt in the third set, trailing 3-1, with the match level at a set apiece. He also had a win over Thomas Johansson at the Copenhagen Open in 2000.
