( CNN ) -- They are former Olympic doubles champions , but Switzerland 's `` dream team '' of Roger Federer and Stanislas Wawrinka suffered another Davis Cup disaster on Saturday . Federer , a 17-time grand slam winner , and 2014 Australian Open champion Wawrinka crashed to a fourth successive defeat as a pairing in the international men 's tennis tournament as unfancied Kazakhstan took a 2-1 lead in the quarterfinal tie . Andrey Golubev , who upset Wawrinka in Friday 's singles , teamed up with debutant Aleksandr Nedovyesov to triumph 6-4 7-6 ( 7-5 ) 4-6 7-6 ( 8-6 ) in match lasting just under three hours in Geneva . `` It feels special . That was my first match for the Kazakhstan Davis Cup team , '' said Nedovyesov , whose only previous appearance in the competition was for his native Ukraine in 2005 . The 27-year-old is ranked 76th in singles and 126th in doubles . `` They are Olympic champions but honestly it does n't matter who I beat , I 'm just proud of my team and proud of my country , '' he added . Russia-born Golubev , who is ranked 61st , continued his unbeaten run in the competition this season . `` Against those guys you have to play an almost perfect match and I 'm happy we did that today , '' the 26-year-old said . Golubev , who won both singles matches in the opening round against Belgium , will play former world No . 1 Federer in what could be the decisive rubber on Sunday . Third-ranked Wawrinka will try to keep Switzerland 's semifinal hopes alive in the first of the reverse singles when he takes on world No . 56 Mikhail Kukushkin -- also born in Russia . Federer and Wawrinka were playing together for their country for the first time this season , but had lost their previous three matches in 2011 and 2012 following Olympic success at Beijing 2008 . `` I 'm not overly worried about what happened the last couple of days , '' Federer said . `` We are good players and we are the favorites still for each singles reverse match but we have no more margin for error so we are aware of that and , who knows , that 's maybe going to make us play even better , so I 'm really excited about tomorrow . '' The winner of this tie will next play either Italy or Great Britain , which took a 2-1 lead in Naples after Andy Murray won his rain-delayed singles match and then returned to the clay court to triumph in the doubles . The world No . 8 completed a 6-4 7-5 6-3 win over Andreas Seppi before teaming up with Colin Fleming to beat Fabio Bognini and Simone Bolelli 6-3 6-2 3-6 7-5 . Britain has not reached the semifinals since the World Group format was introduced in 1981 , while Italy 's last appearance was in 1998 . The defending champion Czech Republic team marched into the last four after sealing an unbeatable 3-0 lead against Japan in Tokyo . Lukas Rosol and Radek Stepanek won 6-4 6-4 6-4 against Tatsuma Ito and Yasutaka Uchiyama to set up a clash with either France or Germany . Both teams are missing their No . 1 player , with Tomas Berdych absent for the Czechs and the injured Kei Nishikori out for Japan . France 's hopes of a third semifinal in five years remain alive after Julien Benneteau and Michael Llodra beat Tobias Kamke and Andre Begemann 6-1 7-6 ( 7-5 ) 4-6 7-5 in Nancy . The visitors will seek to come from 2-0 down for the fourth time in the nation 's competition history , having last done so against Italy in 1996 . Meanwhile , Switzerland also suffered a defeat at WTA Tour tournament in Charleston , South Carolina on Saturday as highly-rated teenager Belinda Bencic lost in her first top-level semifinal . The 17-year-old upset Italian third seed Sara Errani at the Family Circle Cup on Friday , but could not repeat that form in another three-set match against Jana Cepelova . The 21-year-old Slovakian reached her first WTA final by triumphing 6-4 5-7 7-6 ( 9-7 ) on the green clay . Ranked 78th , she followed up shock wins over world No . 1 Serena Williams , Russian Elena Vesnina and compatriot Daniela Hantuchova . Cepelova will next play German Andrea Petkovic , who beat young Canadian sixth seed Eugenie Bouchard 1-6 6-3 7-5 in Saturday 's opening semifinal . Bouchard beat former No . 1 Jelena Jankovic in her previous match but the 20-year-old -- who reached the Australian Open semifinals in January -- could not continue that form against Petkovic , a former top-10 player who is rebuilding her career after long-term injury problems .
