Federer, Serena take titles in Cincinnati
TENNIS • Roger Federer won an unprecedented sixth championship in Cincinnati, overcoming one bad set. Serena Williams dominated for her first title.
Federer extended his record of finals perfection in Cincinnati, beating David Ferrer 6-3, 1-6, 6-2 in the Western & Southern Open on Sunday. He's won all six times he's reached the tournament's title match.
The latest came against an opponent he has dominated throughout his career. Federer improved to 16-0 against Ferrer, who has won only five sets off him overall.
Earlier on Sunday, Williams finally got the one that had always slipped away. And she did it so convincingly that she came away thinking another title could be coming soon.
Williams needed only 62 minutes to beat Ana Ivanovic 6-4, 6-1 for a personal breakthrough. She'd never even reached the finals in Cincinnati until last year, when she fell apart and lost to Victoria Azarenka on a third-set tiebreaker.
