ISTANBUL (AP) -- Caroline Wozniacki overpowered second-seeded Roberta Vinci 6-1, 6-1 Sunday to win the Istanbul Cup final and clinch her first WTA title of the year and 22nd overall.

Top-seeded Wozniacki needed only 67 minutes against the 24th-ranked Italian at the hard-court Koza World of Sport Complex. Wozniacki won 76 percent of points on her first serve - compared to just 43 percent for Vinci - and also saved all six break points against her.

''I served well and pushed her around the court,'' Wozniacki said.

The two players are 2-2 in head-to-heads with Vinci beating the Dane when she was the top-ranked player in 2011.

The 24-year-old Wozniacki, now ranked 15th, has won at least one WTA title every year since 2008.
