Roddick won his first title in five months in San Jose

The 25-year-old eased through 6-4 7-5 to seal his first ATP Tour trophy since August and his third San Jose victory.

"I'm happy with the way I played this week," said Roddick. "Sometimes it's about staying alive in a tournament and giving yourself a chance to play well.

"The more you play, the more comfortable you feel on court. I'm happy I found my form."

The American broke Stepanek in the opening game of the match when the Czech missed a forehand volley and he was able to sit on the lead to take the first set.

Stepanek served better in the second set and fought off break points in the third game.

But he was broken to 6-5 thanks to a massive Roddick forehand pass and the home favourite sealed his win with a massive ace in the next game.

"He just served too good to give me a chance," said Stepanek.

"That's what he did perfectly. Usually I take the rhythm from the players and today I didn't have any."
