LONDON — Top-ranked Ana Ivanovic withdrew from the Wimbledon warmup tournament next week at Eastbourne, citing an injured right abductor muscle.

Ivanovic assumed the No. 1 ranking by winning the French Open last week.

"I have a problem with my abductor. I am also mentally exhausted after the French Open — I am not ready to compete so soon after winning my first Grand Slam," the 20-year-old Serbian player said. "I have taken this decision with some regret."
