MASON, Ohio (AP) A rested Roger Federer tries for an unprecedented seventh title in Cincinnati this week while polishing his game for the U.S. Open.
Federer practiced on Sunday as the Western & Southern Open began with a pair of men's matches. On the women's side, Serena Williams is trying for her second straight Cincinnati title.
Federer decided to sit out the Rogers Cup in Montreal last week, opting to stay home in Switzerland so he could rest and practice. He won his sixth title in Cincinnati last year, improving to 6-0 when he reaches the final.
Novak Djokovic is the top seed. He has never won in Cincinnati, the only Masters tournament title that has eluded him.
