NEW YORK (AP) - 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. She will rise to at least the low 50s on the strength of this run.
She added the Li victory to earlier wins over No. 3 Venus Williams and No. 14 Marion Bartoli. Clijsters will face No. 2 Serena Williams or No. 10 Flavia Pennetta in the semifinals.
