Agassi Gets a Shot to Deal With Back Pain

"I'm definitely satisfied with the way everything went today," said Williams, 24, whose ranking has plunged to 91st as a result of her injury-related inactivity.

Top-seeded Amelie Mauresmo resumed her rain-suspended match against German qualifier Kristina Barrois with ruthless efficiency, winning five consecutive games to close it, 6-1, 7-5.

Second-seeded Rafael Nadal breezed past Mark Philippoussis, 6-4, 6-4, 6-4.

Third-seeded Maria Sharapova dazzled in the evening session, ousting Michaella Krajicek, 6-3, 6-0. The 6-foot-2 Sharapova took the court in a beaded black sheath that she said was inspired by Audrey Hepburn in "Breakfast at Tiffany's." Her tennis outfit for subsequent day-time matches, she added, would be different.

But she had little to say when asked about the buzz that she's dating Andy Roddick, whose second-round match was to follow hers on center court. "I really don't talk about my personal life," she said.

Roddick celebrated his 24th birthday Wednesday by ousting Kristian Pless, 6-3, 7-6 (7-3), 6-3.

Fifth-seeded James Blake subdued Juan Monaco of Argentina, 6-3, 5-7, 7-6 (9-7).

Washington native Shenay Perry, enjoying a career-high 40th ranking, fell to Eleni Daniilidou, 6-0, 6-2. Perry never managed to break serve and was let down repeatedly by her backhand. She declined an interview request afterward.

Rockville's Paul Goldstein outlasted fellow American Jesse Witten, 6-3, 6-4, 2-6, 3-6, 6-1.
