Defending champion Ivanovic loses at French Open

PARIS — Defending champion Ana Ivanovic has lost at the French Open, losing to Victoria Azarenka of Belarus 6-2, 6-3 in the fourth round.

The eighth-seeded Serb called for a trainer to look at her neck before the final game of the first set on Sunday. Azarenka then held to take the lead, and broke Ivanovic’s serve in the first and third games of the second set to take a 4-0 lead.

Ivanovic won her only Grand Slam tournament title at last year’s French Open.
