It took three sets, but defending ladies champ Kim Clijsters beat back a strong challenge from Samantha Stosur in the US Open quarterfinals in New York Tuesday evening. The second-seeded Clijsters downed Stosur, the fifth seed, 6-4, 5-7, 6-3.
As befitted their seeding, this was a close match throughout. Despite having more unforced errors (43-36), Clijsters had a better first-serve performance and hit more winners (25-23) than Stosur. Clijsters also took advantage of break-point opportunities and net approaches.
