No. 6 seed Tomas Berdych defeated No. 11 Nicolas Almagro 7-6 (4), 6-4, 6-1 on Monday to advance to the quarterfinals of the U.S. Open, where he'll face a well-rested Roger Federer.

Sixth-seeded Berdych wrapped up his match at about the same time Federer's opponent, Mardy Fish, withdrew for undisclosed health reasons.

Berdych needed exactly two hours to beat Almagro and make his first U.S. Open quarterfinal. Berdych finished with 39 winners and only 16 unforced errors.

Berdych is 4-11 lifetime against Federer, but 3-3 in the last six matchups, including a win at their last Grand Slam meeting, the quarterfinals of Wimbledon in 2010.
