Andy Roddick broke his own record for fastest serve with a 153-mph ace yesterday during a 6-3, 6-3 victory over Paradorn Srichaphan at the Queen's Club grass-court tournament in London.

"I wasn't trying to hit it any harder than normal and I didn't really realize until the crowd started cheering and I saw Paradorn smiling," Roddick said. "I was surprised because it was against the wind."

Roddick, the top-seeded defending champion at Queens, broke the seventh-seeded Srichaphan twice in the opening set. After an exchange of breaks early in the second set, Roddick won four of five games to close out a 66-minute victory.

He will face Lleyton Hewitt in the semifinals. The three-time Queen's champion, who has a career 20-1 record at the event, won the last four games of each set to defeat Russia's Igor Andreev, 6-3, 7-5.

Sebastien Grosjean downed Radek Stepanek of the Czech Republic, 6-3, 6-3, and will play in the other semifinal against Hyung Taik Lee of South Korea, who defeated Karol Beck of Slovakia, 6-3, 6-4.

* NAVRATILOVA IN, KUERTEN OUT: Martina Navratilova will play singles at Wimbledon for the first time in a decade.

The nine-time Wimbledon singles champion was awarded a wild card, signaling her return 10 years after she lost to Conchita Martinez in the 1994 final -- and 31 years after she made her debut at the All England club.

The 47-year-old Navratilova also played singles at the French Open last month, losing a first-round match. She has said that this season will be her last of competitive tennis.

Wimbledon begins June 21 and ends July 4. . . .

Three-time French Open champion Gustavo Kuerten pulled out of Wimbledon because of a hip injury. Wimbledon organizers also announced the withdrawal of Argentina's Mariano Zabaleta, Paul-Henri Mathieu of France, Finland's Jarkko Nieminen and Morocco's Younes El Aynaoui.

* GERRY WEBER OPEN: Top-ranked Roger Federer moved into the semifinals with a 6-3, 7-5 victory over Arnaud Clement in Halle, Germany.

Federer will face third-seeded Jiri Novak in today's semifinals. Novak beat Tommy Haas, 6-4, 7-6 (7-1), at the warm-up event for Wimbledon.

The other semifinal will match American Mardy Fish, seeded sixth, against second-seeded Rainer Schuettler.
