The top half of the women's singles semi-final bracket has been set.
It was top-seeded Serena Williams over-powering Russian 5th seed Maria Sharapova, downing her in straight-sets, 6-4, 6-1 to move into the final-4 in Melbourne.
This marks Williams' 18th win over Sharapova.
"I don't know. Something about her game (Maria Sharapova). I like the way she hits the ball. Plus, when I play her, I know automatically I have to step up my game. I think that makes me play better. When I play better, when I'm forced to play better, I don't know, I do well."
Williams is set to take on 4th seeded Agnieszka Radwanska in the semi-finals, after she rolled-over Spain's Carla Suarez-Navarro in straight-sets, 6-1, 6-3.
