Kim Clijsters Reaches U.S. Open Semis

Kim Clijsters has kept her comeback on track, moving into the semifinals of the U.S. Open with a two-set victory over China's Li Na. Clijsters is unseeded and making her first appearance at the Open since she won it in 2005. She defeated her 18th-seeded opponent 6-2, 6-4 on Tuesday. The Belgian is returning to tennis after taking two years off, during which she had a baby girl. She entered Flushing Meadows unranked because she hadn't played enough matches in her comeback.
