Serena Williams is through to the quarterfinals of the US Open after beating Estonian Kaia Kanepi in three sets.
The six-time champion, playing not as sharp as when she played her sister Venus on Friday, raced through the first set with a bagel, but her performance dipped in the second set as she lost 4-6.
Kanepi was leading the second set 5-2 at a stage, with the 23 time Grand Slam champion struggling in vain to force a tie break.
It was the first time that Williams dropped a set in her encounters with Kanepi.
In the third set, Williams raced to 3-0 lead to make her uncatchable by her Estonian opponent.
