Clijsters sets up semi-final meeting with Williams

Second seed Kim Clijsters is looking forward to a US Open semi-final against Venus Williams but she will have to improve on an error-strewn display in the last eight against Sam Stosur.

Clijsters was sorely out of form for much of her 6-4 5-7 6-3 win over fifth seed Stosur on Arthur Ashe court, but found just enough composure to emerge victorious for the 19th time in a row at Flushing Meadows.
