Defending champion Roger Federer was extended to three sets by Philipp Kohlschreiber Thursday in the second at his home event in Basel. Federer advanced 6-4, 4-6, 6-4 over his friend who he now leads 11-0.
“It was extremely difficult, especially midway through the second and the beginning of the third,” said Federer. “It was a tough set and a half for me. I wasn’t struggling, but I wasn’t quite feeling it.
“The spectators tonight maybe gave me that last push I needed, giving me energy and carrying me over the finish line.”
After his 55th win over the season, Federer will now face David Goffin on Friday.
Other winners today were a pair of Americans as Jack Sock beat John Isner in straights and Donald Young shocked Kevin Anderson. The two will meet tomorrow.
“Those matches are never fun, playing one of your best friends on the tour,” said Sock after his 7-6, 6-3 win over Isner. “It never sits to well after the match. It’s part of the game. Somebody’s got to win. He’s done it to me a few times. Fortunately, today I was able to get through.”
Richard Gasquet kept his minuscule London hopes alive beating Dominic Thiem. Gasquet, who must win both Basel and Paris to have any chance at London, now takes on the towering Ivo Karlovic.
“It was a super match for me and keeps me in the race for London,” Gasquet said. “Karlovic is such a tough opponent. His serve is unbelievable. I just have to concentrate on returns, I will need to play really well.”
Also tomorrow, Rafael Nadal continues his rebuild against former US Open champion Marin Cilic. Nadal leads 2-1 but this is the Croat’s best surface and the two haven’t played since 2011.
