NEW YORK (AP) -- Tommy Haas has officially withdrawn from the U.S. Open because of surgery on his right shoulder, opening up a spot on the main draw for Marcos Baghdatis.

Haas, currently ranked 26th, is out for the season after having a fourth operation on his shoulder.

The 105th-ranked Baghdatis was the runner-up at the 2006 Australian Open and a semifinalist at Wimbledon that year.

His best U.S. Open showing was last year, when he made it to the third round.
