Del Potro beats Berdych; Federer up next
PARIS (AP)—Juan Martin del Potro set up a French Open quarterfinal against Roger Federer by finishing off a 7-6 (6), 1-6, 6-3, 7-5 victory over Tomas Berdych on Monday in a match stopped the night before because of darkness after three sets.
The No. 9-seeded del Potro broke No. 7 Berdych at love in the final game.
Del Potro is 2-11 against Federer, but one of the victories came in the 2009 U.S. Open final, when the Argentine won his only Grand Slam title.
One of del Potro's losses to Federer was in the 2009 French Open semifinals. That's the only time del Potro made it that far at Roland Garros.
Berdych was a French Open semifinalist in 2010 then was the runner-up at Wimbledon later that year.
