After 2 years off, Kim Clijsters needed just two sets to capture US Open title No. 2 tonight at Flushing Meadows. The 7-5, 6-3 victory over Caroline Wozniacki of Denmark capped a dramatic run by the 26-year-old Belgian, who was unseeded in her third tournament since un-retiring. Her 18-month-old daughter, Jada, was in the stands tonight, reports the New York Times. (More Kim Clijsters stories.)
