HALLE, Germany — 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 much more, beating Philipp Kohlschreiber 6-3, 6-4 in Sunday's final for his 10th grass title. That matches Pete Sampras' Open era record of 10 grass-court titles and takes his unbeaten streak on grass to 59 matches.

To further boost his confidence, Federer sailed through the Wimbledon warmup tournament without dropping a set or his serve.

"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 a tournament in Doha in 2005 without being broken.

He restored some momentum after one of his worst defeats — a rout in the French Open final last Sunday at the hands of Nadal. Federer took just four games.

NADAL WINS 1ST GRASS-COURT TITLE: At London, Rafael Nadal claimed his first career grass-court title Sunday, defeating Novak Djokovic 7-6 (5), 7-5 in the Queen's Club final to become the first Spaniard to win on grass in 36 years.

It was the French Open champion's third win in the last three tournaments over the second-seeded Djokovic, following semifinal victories in Hamburg and at Roland Garros. Andres Gimeno was the last Spaniard to win on grass, at Eastbourne in 1972.

Nadal is also the first player to win at Roland Garros and Queen's Club in the same year since Ilie Nastase in 1973.

"This week was amazing for me," Nadal said.

NIKOLAY DAVYDENKO WINS WARSAW OPEN: At Warsaw, Poland, top-seeded Nikolay Davydenko recaptured the Warsaw Open title when he beat second-seeded Tommy Robredo 6-3, 6-3 in the final Sunday.

Davydenko won the clay-court tournament in 2006, and Robredo won it last year.

The Russian broke Robredo three times in the first set, while giving up his serve once. He needed just one break in the second, saving five break points en route to his third ATP title of the year and 14th of his career.
