Andy Roddick broke his record for fastest serve with a 153-mph ace Friday during a 6-3, 6-3 victory over Paradorn Srichaphan at the Queen's Club grass-court tournament.
Roddick served the ace at 1-0, 15-0 in the second set.
"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 and I didn't think I had that in me."
It's the third time this year Roddick has improved the record. He hit 150 mph in a Davis Cup match against Austria in February, and 152 mph in Davis Cup play against Sweden in April.
"I can't feel the difference between 146 mph and 153," Roddick said. "I can feel when I hit it big, but if you're asking if I know that's it, I have no idea. In my mind, it still counts as just one point in the match. I'm just happy to get through more than I am about hitting a big serve."
Roddick, the top-seeded defending champion at Queens, broke the seventh-seeded Paradorn 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 faces Lleyton Hewitt in the semifinals. The Australian, a three-time Queen's champion, won the last four games of each set to defeat Russia's Igor Andreev 6-3, 7-5.
