Federer, Azarenka win titles in California desert

Azarenka broke Sharapova in the final game, when the Russian double-faulted then shanked a forehand to set up Azarenka's first match point. She won after forcing Sharapova into a desperation defensive shot that sailed beyond the baseline. Azarenka dropped her racket, pumped her right arm and broke into a brief dance while smiling broadly.

She joked that the best thing about being No. 1 is "you don't really have to find yourself in the draw anymore. It's the first one."

It was yet another dominant performance by Azarenka, who improved to 5-3 against Sharapova, including 4-0 in finals. Sharapova hasn't beaten Azarenka in a completed match since 2009; she won last year in Rome when Azarenka retired in the second set with a right elbow injury.

"What was important for me was to try to put as much pressure on her, not to really let her into the match because when she has a little window open she always going to take the opportunity and she's going to fight no matter what the score is," Azarenka said.

Sharapova twice had aces to hold serve in the first set, but her groundstrokes were inconsistent. Azarenka led 4-1 in the second set when Sharapova won two straight games to get to 4-3, capped by a swinging forehand volley winner. But Sharapova won just two points in the final two games to fall to 13-3 on the year.

"I still don't think I was as aggressive as I should be," Sharapova said. "But it's OK. We're going to play against each other a few more times, so I'll have time to change that."
