Shoulder injury forces Sharapova to withdraw

"I lost my concentration," Zvonareva said. "I relaxed a little bit."

The crowd rallied behind Petrova, who evened the match at 5-all. Zvonareva took over the tiebreaker, though, smashing four aces and making quick work of Petrova, denying her a shot at her first career championship.

"I know sometimes how difficult finishing off a match is," Petrova said. "You think if you win this game, the match is yours. You make yourself a little bit nervous because you want it so badly. She started getting frustrated."

Zvonareva said she was bothered by the response of the partisan crowd, including some fans who were talking during points.

"I thought it was a little bit of disrespect from the people," she said, then added most of the fans have been great.

The win made it a good couple of days for Zvonareva, who clinched a berth in next week's WTA Tour Championships in Los Angeles with her win over Capriati.

"I never played it before and championships are always a big story," Zvonareva said.

The Advanta Championships, held from 1971-79 and 1991-2000, was usually the final tournament before the season-ending WTA Tour Championships. When the championships moved from New York to Germany, Advanta was phased out. Advanta returned to the schedule last year.
