HALLE, Germany (AP):

Roger Federer just wanted to survive a couple of rounds at the Gerry Weber Open after his painful French Open loss to Rafael Nadal.

The top-ranked Swiss did even better by reaching the final again and beating Philipp Kohlschreiber 6-3, 6-4 yesterday for his fifth title in Halle and 55th of his career. He also extended his unbeaten streak on grass to 59 matches, and matched Pete Sampras' Open era record of 10 grass-court titles.

As another boost to his confidence, Federer sailed through the Wimbledon warm-up without dropping a set or his serve, though he didn't face another top-10 player.

Special win

"I'm really excited, I think that's the first time in my career I won a title without losing serve," Federer said. "That was very special - and I'm very proud to keep my streak going."

In fact, Federer also won 2005 Doha without being broken. His second title of the year restored some momentum after one of his worst defeats - a rout in the French Open final the previous Sunday at the hands of Nadal. Federer took just four games.
