Dallas - Italy's Roberta Vinci completed her warm-up for the US Open with a straight-sets victory over former world number one Jelena Jankovic in the final of the WTA's Texas Open on Friday.
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.
