Ancic to miss U.S. Open due to recurrence of mononucleosis

NEW YORK -- Croatia's Mario Ancic withdrew from the U.S. Open on Tuesday with a recurrence of mononucleosis, the second straight year the 25th-ranked player was forced to miss the tournament.

Ancic, a former Wimbledon semifinalist, was slowed throughout the 2007 season because of mononucleosis. He pulled out of the Open last August because of an injured right shoulder.

Ancic beat Roger Federer in the first round at Wimbledon in 2002. That had been Federer's most recent loss there until Rafael Nadal beat him in the final this year.
