Top-seeded Maria Sharapova needed just more than hour of play Saturday to claim a third-round victory at the Australian Open in Melbourne.

Sharapova, fourth-seeded Kim Clijsters and sixth-seeded Martina Hingis all posted straight-set victories and moved into the fourth round of the year’s first Grand Slam event. Rain forced the postponement of several other third-round matches, however.

Sharapova ousted 30th-seeded Tathiana Garbin 6-3, 6-1 in running her Grand Slam match winning streak to 10. Her fourth-round match will be against 22nd-seeded Vera Zvonareva, who rolled to a 6-1, 6-2 upset of No. 13 Ana Ivanovic in her Saturday match.
