Serena Williams and Maria Sharapova have set up a tantalizing quarterfinal clash, after both won their fourth round matches on Sunday.

Jamie Whincup's win-or-bust approach again cost him victory in the Bathurst 1000 as Tekno Holden's Will Davison kept his head to score an improbable and emotional win.

For the third year in a row, Whincup engineered his own demise on Sunday, this time attempting a desperate passing move in the closing stages that went horribly wrong.

While he emerged in the lead from the ensuing carnage that eliminated rivals Scott McLaughlin and Garth Tander from the fight for the win, he suffered a 15 second penalty that dropped him to 11th place at the finish.

The Triple Eight-run squad has appealed to overturn the time penalty, which wiped out the 5.2 seconds advantage he had over Davison on the track at the finish, and reinstate Whincup as the winner.

Davison's co-driver Jonathon Webb is also the boss of the small Gold Coast-based squad and along with his father Steve established it from scratch.
