Jankovic and Davenport cruise, Ivanovic battles

By Mark Lamport-Stokes

INDIAN WELLS, California (Reuters) - Serbia's world number four Jelena Jankovic and twice champion Lindsay Davenport coasted through their opening matches in the Pacific Life Open second round on Saturday.

Jankovic, shrugging off strong winds at the Indian Wells Tennis Garden, crushed American wildcard Ahsha Rolle 6-0 6-2 and Davenport advanced when Argentina's Gisela Dulko retired hurt with a thigh strain trailing 2-6.

However, world number two and top-seeded Serb Ana Ivanovic had to fight back after losing the second set before defeating Romania's Ioana Raluca Olaru 6-1 5-7 6-0 in a match lasting one hour, 55 minutes.

Jankovic, who reached her third grand slam semi-final at the Australian Open in January before losing to eventual winner Maria Sharapova, broke Rolle three times in each set to seal victory in just under an hour.

"The first rounds are always tough, especially in the windy conditions, and you have to be really focused and try to move your feet," third-seeded Jankovic told reporters after surprisingly losing the first two games of the second set.

"That's what I did today so I'm really glad with my performance. I'm happy to get through."

American Davenport, champion at Indian Wells in 1997 and 2000 and runner-up here four times, broke in the opening game before Dulko summoned a fitness trainer when losing 2-3 on the Stadium Court.

Dulko, who lost to Davenport in the 2004 quarter-finals at Indian Wells in their only previous meeting, had her right thigh worked on and strapped up but was unable to continue after losing the first set.
