NEW YORK (AP) - A year after skipping the U.S. Open because of a bad knee, 2010 champion Rafael Nadal powered his way back to the semifinals by overwhelming 19th-seeded Tommy Robredo 6-0, 6-2, 6-2 on Wednesday night.

The second-seeded Nadal improved to 20-0 on hard courts in 2013, part of an overall record of 58-3 with nine titles, including his record eighth championship at the French Open in June. At the next Grand Slam tournament, though, Nadal flopped, exiting in the first round at Wimbledon.

That surprising defeat, against a guy ranked 135th, came on June 24. Feels like eons ago. Nadal hasn't lost a match to anyone since.

On Saturday, Nadal will face No. 8 Richard Gasquet, who edged No. 4 David Ferrer 6-3, 6-1, 4-6, 2-6, 6-3 in the quarterfinals.
