Key Biscayne, Fla. - Swapping shrieks along with their shots, Maria Sharapova and Victoria Azarenka made rallies sound like a car alarm.

Sharapova was the soprano, Azarenka the alto, and their alternating arias could be heard on the beach across the street from the Sony Ericsson Open.

But Sharapova was flat and her opponent sharp. Azarenka swept nine consecutive games to take charge Saturday and won the tournament for the second time, beating Sharapova, 6-1, 6-4.

The final matched two of the most notorious grunters in tennis, and while both were noisy, Azarenka's shots had more bang. Sharapova committed 43 unforced errors, held serve only once and came up short with a late comeback bid.

"I played real well the first set," the No. 8-seeded Azarenka said. "Maria is such a great fighter, I knew she was going to fight to the end. She came up with great tennis at the end, and I had to hang in there. That's what paid off."

And who had the better shriek?

"I think mine is quieter," Azarenka said.

Sharapova committed eight errors in the first game alone. She lined one especially unsightly serve into the concrete in front of the net. By the time she found her range, Azarenka led 4-love in the second set.

"It's a little bit too late to pick up the pace when you're down a set and 4-love," Sharapova said. "I wish I picked it up earlier, obviously. She did many things better than I did today."

While the women's tournament was full of surprises, the men's draw is down to the game's top-ranked players. No. 1 Rafael Nadal will play for the championship today against No. 2 Novak Djokovic, who is 23-0 this year.

Sharapova lost in a final for the fourth time since her most recent title, at Strasbourg in May 2010. She's 0-3 in finals at Key Biscayne, where she was also the runner-up in 2005 and 2006.

But the three-time Grand Slam champion is healthy again after battling a series of injuries, as the results are starting to show. She's projected to climb next week to No. 9, the highest she has been ranked since early 2009.

Azarenka's also on the rise, and projected to be ranked No. 6 next week, matching a career-best.

Alas, the 21-year-old Belarussian can't play Key Biscayne every week. She also won the tournament in 2009, stopping Serena Williams in the final. The two titles are the biggest of her career, and she joked she's planning to move to Miami from Minsk.

Serena and Venus Williams, who between them have won eight Key Biscayne titles, missed the tournament for health reasons. But Azarenka still faced a tough path to the final, beating No. 2 Kim Clijsters and No. 3 Vera Zvonareva in straight sets.
