Anastasia PavlyuchenkovaRussian third seed, Anastasia Pavlyuchenkova, defeated compatriot Elena Vesnina 5-7, 7-5, 6-4 on Sunday to capture the WTA Istanbul Cup title in Istanbul, Turkey.

At 19-years-old, Pavlyuchenkova is ranked No. 24, the highest-ranked teenager in the world. It was her second career championship after Monterrey earlier this season.

Pavlyuchenkova did it the hard way, taking the victory after three hours and 10 minutes on the court in the final match, rallying from 0-4 in the second set and 1-3 in the third.

Vesnina, who celebrated her 24th birthday on Sunday, came into Istanbul on a seven-match losing streak, having not won a match on the Tour since Charleston in April.

She won four in a row to reach the Istanbul final, her third career title match after runner-up finishes last year at Auckland (to Elena Dementieva) and New Haven (to Caroline Wozniacki).
