Federer out of Gerry Weber Open

HALLE, Germany -- Roger Federer pulled out of the Gerry Weber Open, his usual grass-court warm-up for Wimbledon, saying Tuesday he is "overwhelmed" and "exhausted after his French Open win.

The withdrawal came two days after Federer's record-tying 14th Grand Slam victory at the French Open, the only major title that had been missing from his resume.

"I sincerely apologize to the tournament organizers, my competitors, and my fans in Germany. I only hope they will understand that I still feel emotionally overwhelmed and exhausted by the incredible events of the past few days," Federer said Tuesday on his Web site.

"It is hard for me to admit, but I simply cannot imagine giving my best effort in another tournament right away and I don't want to risk injury if I am not 100 percent prepared. I need to rest and recuperate," he said.

Federer has won the tournament in Halle five times, and four of those years he went on to win Wimbledon.
