Vinci, seeded third, won the last six games of the second set to complete a 7-5, 6-3 victory. Vinci, making the most of second-seeded Jankovic’s five double faults, claimed her seventh career WTA title and her first of 2012.
It was a morale-boosting victory with the US Open -- the final Grand Slam of the season -- due to start on Monday at Flushing Meadows. Serbia’s Jankovic, meanwhile, missed an opportunity to lift a trophy for the first time since 2010. It was her second appearance in a final this season.
She lost to American Melanie Oudin on the grass courts of Birmingham in June. Vinci, who had booked her spot in the final with a dominant 6-0, 6-0 semi-final win over Serbia’s Bojana Jovanovski on Thursday, found the going tougher against Jankovic, needing just over two hours to triumph.
