Former world No. 1 Jelena Jankovic, former champion and last year's runner-up Svetlana Kuznetsova, and Olympic gold medalist Elena Dementieva emerged as winners of the third round on Wednesday at the U.S. Open.

The second-seeded Jankovic beat Swede Sofia Arvidsson 6-3, 6-7 (5-7), 7-5 in 2 hours, 45 minutes.

Jankovic, who held the No. 1 ranking for one week just two weeks ago, seemed to be sailing smoothly on Day 3, up a set and serving for the match at 5-4 in the second, till she was confronted by Arvidsson.
