GENEVA (AP) — Australian Open champion Stanislas Wawrinka lost to 64th-ranked Andrey Golubev on Friday, giving Kazakhstan a surprising 1-0 lead over Switzerland in the Davis Cup quarterfinals.
Golubev won 7-6 (5), 6-2, 3-6, 7-6 (5) in Wawrinka’s first match in Switzerland since becoming a Grand Slam champion in January.
Most of the 15,000 spectators who gave Wawrinka a huge ovation stepping on court at Palexpo arena were stunned into near silence when Golubev converted his sixth match point with an overhead winner.
“In the beginning, of course I was a little bit tense. I think we both were,” said Golubev, who lost to Wawrinka in the first round in Australia. “I tried to be always aggressive, didn’t give him too much time.”
Wawrinka, ranked No. 3 in the world, was punished for making 70 unforced errors and converting just one of his 10 break points.
The Swiss No. 1 also smashed his racket on the hard-court surface in frustration during the second set.
Roger Federer was to play 56th-ranked Mikhail Kukushkin in the second singles match.
The winner will face Britain or Italy in the semifinals in September.
