Williams: Azarenka clash was like a semi

Serena Williams felt her third-round victory over fourth seed Victoria Azarenka at the US Open yesterday was worthy of a semi-final.

The 28th seed and title favourite looked to be cruising at a set and 5-3 up with three match points but Azarenka fought back, saving a fourth match point, only for Williams to edge the second-set tie-break and win 6-1 7-6 (7-5).
