The sixth-seed, in scintillating form from the baseline, wrapped up her fourth successive victory over the Dane when her opponent struck a forehand service return long.

Jankovic, 25, brought both hands up to her cheeks in a mixture of celebration and relief before waving to the crowd at the Indian Wells Tennis Garden.

"It has been a great two weeks for me, really amazing," a beaming Jankovic said at courtside. "I am just so happy and so thrilled I was able to win this title.

"I want to congratulate Caroline for making it such a great event and also for making it to number two in the world." The 19-year-old Wozniacki, a US Open finalist last year, is projected to climb to a career-high second when the world rankings are released on Monday.

"Jelena played a good match today," the Danish teenager said. "She didn't make a lot of mistakes. I tried to change it when I saw it was not going way but I just made a few too many errors at the important points.

"I couldn't really get to play the game that I wanted to play, and Jelena took advantage of that." Jankovic, a former world No.1, broke the Dane in the first and third games of the match to race into a 4-0 lead.

Although she surprisingly lost her own serve in the sixth, she immediately broke back before taking the opening set.

The Serb, wearing a lime-green dress, tightened her control when she again broke in the first game of the second after the Dane netted a forehand.

The rest of the set went with serve and Jankovic, playing in her first WTA final of the year, earned match point with a backhand winner down the line before sealing victory when Wozniacki's service return landed long.
