Roger Federer and Andy Roddick overcame minor worries and moved on at the Cincinnati Masters. Andre Agassi dropped out and headed home with a lot on his mind.

Federer worked off the rust from a five-week layoff caused by a sore foot, and Roddick compensated for an undependable serve during their first-round wins yesterday in Mason, Ohio.

Agassi came and went without lifting a racket.

The 35-year-old defending champion decided to withdraw because a chronic back problem flared up. He hoped that a couple of weeks of rest and perhaps another cortisone shot would soothe an inflamed nerve, allowing him to play in the U.S. Open.

"Unfortunately, I know this process all too well," said Agassi, bothered by back problems in recent years. "I know exactly what it needs."

Federer needs to sharpen his game after missing so much time. The world's top-ranked player hadn't entered a tournament since winning his third straight Wimbledon title, and it showed.

During the first set of a 7-6 (7-3), 7-5 win over James Blake, Federer set up for a routine backhand and barely touched the ball, which skittered off the tip of his racket. Federer dropped his head in disbelief.

Meantime, Roddick struggled with his serve, but was solid in every other aspect of a rejuvenating 6-3, 6-4 win over Jurgen Melzer.
