Former champion Ana Ivanovic of Serbia has lost in the second round of the French Open.
Ivanovic, who won in Roland Garros two years ago, lost 6-3, 6-0 to 28th-seeded Alisa Kleybanova of Russia on Thursday.
The former No. 1 Ivanovic has seen her form and ranking gradually decline since winning her only Grand Slam title. She is 42nd in the WTA rankings following a string of poor results over the past two years.
Kleybanova closed out the match on her first chance with a winning serve and advanced to the third round in Paris for the first time. The 20-year-old Russian won her first title earlier this year at Kuala Lumpur.
