GRAPEVINE -- Roberta Vinci capped a week of tennis in Dallas-Fort Worth by defeating Jelena Jankovic, the world's former No. 1-ranked player, in two sets, 7-5, 6-3, on Friday to win the WTA Texas Tennis Open at the Hilton DFW Lakes.The tournament's No. 3 seed needed a little more than two hours to dispose of the Serbian-native in a U.S. Open tune-up.After depositing the $37,000 winner's check but before heading to Flushing, N.Y., next week for the beginning of the U.S. championships, this Italian, No. 23 in the world, will make a pit stop.For a good ol' fashioned American cheeseburger."With fries," Vinci said with a laugh. "It's America. I'm a little bit American, I think."It was a tough week. We played a really good final. She's a great player."Marina Erakovic and Heather Watson captured the doubles final by topping Liga Dekmeijere and Irina Falconi, 6-3, 6-0.Vinci had to fight back from an early deficit to top Jankovic, a 12-time winner who broke Vinci to open the match and appeared in control at 3-1.But Vinci, who admitted to battling nerves in the quarterfinals, held and recorded a break of her own to get back to even. She took her first lead when she again held serve in the next game."I had a lot of chances [early]," Vinci said. "It was 3-1 but in my mind I'm thinking, 'don't worry, you can do it. It's not [an easy] 3-1.'"Jankovic broke back and served for the set at 5-4.At 30-15, a close call on a Vinci return went against Jankovic and instead of being up two set points, the game and match turned.Vinci, who served under 50 percent on first serves, went on to again break her rival and win the next five games.Vinci used three sharp forehand winners and a double fault by Jankovic to win the first set."It was a close call," Jankovic said of the point at 5-4. "If that ball went my way, it would have been two set points. But after that everything seemed to go down hill, and I started making a lot of errors."Jankovic, though down 3-0 in the second set, wouldn't go away, winning the next three games and appearing poised to break Vinci's serve at love-40.What ensued was an entertaining display of great shot making with two long rallies that Vinci finally got the best of. Vinci got the game to deuce by racing from the back to just reach Jankovic's soft drop shot near the net and find the inside of the line on a return."Again, she came up with some defensive slices in the corner," said Jankovic, who took home $19,100 as the runner-up. "She played unbelievable. She came up with some really good shots."Vinci's road to the final included victories against Su-Wei Hsieh, Polona Hercog and Chanelle Scheepers and Bojana Jovanovski.
