Cincinnati

CINCINNATI - Serbian tennis player Ana Ivanovic advanced to the second round of the WTA Premier event in Cincinnati after beating Romania's Sorana Cirstea 6-1, 7-5 in the opening round on Monday.

Ivanovic will next play the winner of the all-American clash between Nicole Gibbs and Christina McHale.

The world number one pair of Novak Djokovic and Serena Williams aim to bounce back this week at the Cincinnati Masters, the last major tuneup before the US Open.
      
Djokovic was stung by a third-round hammering by France's Jo-Wilfried Tsonga, who got past the Serb in less than an hour en route to taking the ATP Masters title in Toronto on Sunday.
      

Romanian female tennis player Simona Halep, currently 3rd in the WTA ranking, will become the world's No. 2 after China's Na Li announced she is forced to skip a series of tournaments because of a long-standing knee injury.
