Svetlana Kuznetsova of Russia claimed her first WTA title in 10 months at San Diego Open on Sunday by beating Polish fourth seed Agnieszka Radwanska 6-4, 6-7 (9), 6-3.

It was the veteran's 13th career title but the first in the recent 10 months since she beat Radwanska in the Beijing final last October.

The two-time Grand Slam champion botched four match points in the second-set tie-breaker after squandering leads of 4-0 and 6-3, double-faulting twice on match point to open the door for 10th-ranked Radwanska to force a third set.
