AO Update: No. 5 Ivanovic ousted in third round

Fortunes change quickly in tennis. Last year’s French Open champion and, for a time, No. 1 ranked player, Ana Ivanovic’s hopes of a return trip to the Australian Open final fell apart in a barrage of mistakes Friday as Russia’s Alisa Kleybanova ousted the 2008 runner-up with a 7-5, 6-7 (5), 6-2 victory in the third round.

After the match, Kleybanova, who reached the fourth round at Wimbledon last year in her third Grand Slam and is seeded 29th, dropped to her knees in disbelief.

Ivanovic, with her 50 unforced errors, became the second top women’s seed (after Venus Williams) to bow out of the tournament.

Meanwhile Jelena Dokic  pulled off the latest of her Australian Open upsets against Caroline Wozniacki, the 18-year-old from Denmark and No. 11 seed, 3-6, 6-1, 6-2.

World number one Jelena Jankovic, wearing new threads by ANTA, ground out another tough win to reach fourth round Friday. She beat Japan’s Ai Sugiyama 6-4, 6-4 but for the second time in the tournament struggled to land a killer blow against an opponent who, on paper, should have been easy pickings for the top seed.
