BEIJING, Aug 18: Serbia’s Jelena Jankovic was ousted as world No 1 by compatriot Ana Ivanovic on Monday after holding the position for just one week.

Ivanovic, who was No 1 for nine weeks before Jankovic’s brief reign, will retain top spot for at least three weeks, according to WTA.

The 20-year-old French Open champion pulled out of the Beijing Olympics last week with a right thumb injury.

Jankovic lost to Russia’s Dinara Safina in the quarter-finals.

Both will be playing in the US Open which starts next Monday.—Reuters
