INDIAN WELLS, California, March 15 Holder Jelena Jankovic was eliminated from the Indian Wells WTA tournament by former champion and fellow Serb Ana Ivanovic on Tuesday, losing 6-4 6-2 in the fourth round.
Sixth-seeded Jankovic, who beat Denmark's Caroline Wozniacki in last year's final, converted only one of seven breakpoint opportunities as she was beaten by Ivanovic for the first time in their last three meetings.
"I felt like my game was not really there. I wasn't really doing the right things out there," Jankovic told reporters after being broken once in the opening set and three times in the second.
"I felt really flat, my feet were not moving," added the 26-year-old Serb. "A lot of times I felt stuck on my shots and I didn't really move up to the ball as well as I was doing in the previous matches."
Nineteenth-seeded Ivanovic, who beat Jankovic in the 2008 semi-finals at Indian Wells on her way to winning that year's title, improved her overall win-loss record against her compatriot to 7-3.
"She played such a great match today," said Jankovic, who had been bidding to become the second woman, after Martina Navratilova in 1991, to win back-to-back titles here.
"She really didn't make a lot of unforced errors. She hit the ball pretty clean, pretty solid. I felt really flat, and she took advantage of all that."
Ivanovic will face either second-seeded Belgian Kim Clijsters or 15th seed Marion Bartoli of France in the last eight.
Clijsters, Indian Wells champion in 2003 and 2005, and Bartoli were playing later on Tuesday.
In the final women's match of the day session on the showpiece stadium court, top seed Wozniacki was scheduled to take on 22nd-seeded Russian Alisa Kleybanova. (Editing by Frank Pingue; To query or comment on this story email firstname.lastname@example.org)
