John Isner jolted Roger Federer with his big serve and booming groundstrokes Friday, winning 4-6, 6-3, 7-6 (4), 6-2 and giving the United States a 2-0 lead against Switzerland in the first round of the Davis Cup at Fribourg, Switzerland.
Isner challenged the Swiss star in long rallies on the indoor clay court, sending Federer to his first loss in Davis Cup singles in eight years and quieting a Swiss crowd unaccustomed to such outcomes.
"I thought he played great," Federer said. "He played it tough and served great when he had to. I just missed a couple more opportunities than he did and that's what cost me the match."
Isner, 26, called it the "biggest win of my career thus far."
"I'm very proud of it," he said. "I played those break points down very well. It turned the match a little for me."
The U.S. can eliminate Switzerland in doubles in the best-of-five series Saturday. Mike Bryan and teenager Ryan Harrison will face Federer and Wawrinka.
"It's been a difficult day for us," Federer said, adding: "We still have a chance to go through. I'm going to enjoy the challenge."
Seven other first-round series in the top tier of Davis Cup were contested Friday. Croatia and Japan were tied 1-1, Ahead 2-0 were Serbia (vs. Sweden), Austria (vs. Russia), Argentina (vs. Germany), Spain (vs. Kazakhstan) and Czech Republic (vs. Italy). The other matchup was Canada vs. France.
Kerber broke serve three times in the first set and rallied from 3-1 down in the second, clinching the victory when Sharapova hit a forehand long.
