It was the Serbs third straight title, following tournament victories at the China Open at Beijing and the Porsche Tennis Grand Prix at Stuttgart, Germany.

"She's a really tough opponent," said Jankovic, who had beaten her Russian opponent in both previous tournaments. "She runs a lot of balls (but) all of my opponents this week were tough and I had to work hard every match."

Jankovic won $196,900 and become the first woman since Nicole Vaidisova in 2005 to win three times in three weeks.

Since her runner-up finish to Serena Williams at the U.S. Open, Jankovic has improved from 6-10 to 9-10 lifetime in ATP Tour singles finals.

Zvonareva was playing her 16th career singles final (7-9 record).
