Cilic beats Fish at Pilot Pen for first ATP win

"I just didn't have power, especially in the third set," Chakvetadze said. "If you are not able to run and fight on the court, then you're going to lose the match."

The loss was the 21-year-old Russian's first in a WTA final. She had been 7-0 during her short career, including a win earlier this season indoors at Paris. Despite her loss, Chakvetadze expected to move up in the rankings, to No. 9 from No. 11 next week.

"I'm actually pleased with my game," she said. "Not today. But if I compare it to one month ago, it's much better. So I look forward to play the U.S. Open, the most important tournament obviously is coming in two days. I hope I will stay fresh for each match."

Wozniacki has moved up from No. 64 in January to No. 22, and is expected to break into the top 20 for the first time.

The teenager still has a year of high school left, and said until recently, she considered her biggest tennis achievement beating her older brother.

"I am having fun," Wozniacki said. "I enjoy playing. I enjoy playing for a big crowd. You know, when you're in the finals, you don't have anything to lose. You can just win."
