Maria Sharapova rallied from a set down to defeat Venus Williams 2-6, 6-2, 7-5 to advance to the fourth round.
The second seed survived a tough encounter against her unseeded American rival, who had won their last meeting at Wimbledon two years ago, coming through an error-strewn match in which the pair combined for 25 double faults and 91 unforced errors.
Sharapova next takes on Venus' sister, Serena, who defeated her 6-1, 6-2 in the Australian Open finals earlier in January.
