Moscow, Russia -- (Sports Network) - Jelena Jankovic of Serbia rolled to a straight-set victory over Russia's Vera Zvonareva in Sunday's final of the Kremlin Cup, strengthening her position as world No. 1 with her third WTA title in as many weeks.

The top-seeded Jankovic downed Zvonareva with relative ease 6-2, 6-4, needing an hour and 21 minutes to become the first woman since Nicole Vaidisova in 2005 to win three times in three weeks. Jankovic also won in Beijing and at Stuttgart prior to the Kremlin Cup victory.

The easy win in the final capped a tough ride to Sunday for Jankovic, who dropped the first set of her opener against Vera Dushevina, trailed 3-1 in both sets of her quarterfinal win over Flavia Pennetta, and rebounded from an awful start in her 0-6, 6-1, 6-0 win in Saturday's semifinal over the No. 3 seed and defending champion Elena Dementieva.

"All of my opponents this week were tough and I had to work hard every match," said Jankovic. "All of my opponents in the last few weeks have been tough for me. Winning three tournaments in a row is a great result. I've been trying my best."

The world's top-ranked player also captured the French Open tuneup in Rome earlier this year and has nine titles for her career. She's also been a runner-up twice this season, losing to Serena Williams in finals at Miami and the U.S. Open.

Zvonareva, meanwhile, failed in her bid for her third title of 2008. She also won at Prague in May and last month in Guangzhou to increase her career victory haul to seven. In addition to her victories, she has also lost in the title matches at Hobart, Doha and Charleston.

Jankovic improved to 6-3 in her career against Zvonareva. The two had split six career meetings prior to this win streak for Jankovic, who bounced Zvonareva in the semifinals at Beijing two weeks ago and in the quarterfinals last week in Stuttgart.

Sunday's matchup was the fifth this season between the two, but first in a final. Before the last two matchups, Zvonareva prevailed in the quarterfinals at Charleston and Jankovic was a straight-set winner in the semifinals in Miami.

The only previous meeting in a final came last year in Auckland, where Jankovic prevailed with a 7-6 (11-9), 5-7, 6-3 triumph.

Jankovic took home a purse of $196,900 for winning the title on Sunday.
