MASON, Ohio — Roger Federer overcame a tough start and emerged from his string of subpar showings since Wimbledon, beating Tommy Haas 1-6, 7-5, 6-3 on Thursday to advance to the quarterfinals at the Western & Southern Open.
He'll play fourth-seeded Rafael Nadal tonight, reprising one of tennis' greatest rivalries. Nadal leads the series 20-10, including a pair of wins over Federer this season.
Nadal beat Grigor Dimitrov 6-2, 5-7, 6-2 in a 2-hour evening match.
While Federer took a step, No. 1 Novak Djokovic got one win closer to a little ATP history. He needed only 50 minutes to beat qualifier David Goffin, 6-2, 6-0 and reach the quarterfinals.
Also reaching the quarterfinals were second-seeded Andy Murray, sixth-seeded Tomas Berdych, seventh-seeded Juan Martin del Potro and Russian qualifier Dmitry Tursunov, who upset third-seeded David Ferrer.
The women's side played mostly to form, with No. 1 Serena Williams beating Germany's Mona Barthel 6-4, 6-1 in only 63 minutes on Thursday night, reaching the quarterfinals in a tournament where she's never reached the final.
