NEW YORK — Janko Tipsarevic advanced to the fourth round of the U.S. Open when ninth-seeded Tomas Berdych retired in the second set Saturday.

The 20th-seeded Tipsarevic was leading 6-4, 5-0 when Berdych decided he couldn't keep playing with the injury to his right, serving shoulder.

Tipsarevic upset Andy Roddick in the second round at the Open last year. He matched his best Grand Slam result by reaching the round of 16. The Serb is ranked No. 20, a career high.

Berdych's shoulder started bothering him during his victory over Roger Federer last month in the quarterfinals at Cincinnati. The Czech had to retire after the first set of his next match.

Berdych received treatment between sets Saturday.

The 2010 Wimbledon runner-up made just 49 percent of his first serves and had 22 unforced errors in 15 games.
