Stoner dominates practice for Australian GP
Philip Island (Australia): Casey Stoner dominated both practice sessions Friday for the Australian GP as he chases his fifth straight win at his home race and a chance to clinch the 2011 MotoGP world championship.

Stoner failed to better his time in the afternoon session, but his 1:30.535 was enough to edge out Honda Gresini rider Marco Simoncelli`s third overall quickest 1:30.912.
Simoncelli spilled his bike in each session, but was unhurt and able to ride back to the pits for minor repairs.
Stoner, whose 26th birthday coincides with Sunday`s race, can seal the MotoGP rider`s title with if he scores ten points more than Lorenzo. He said his chances of taking out the championship in front of his hometown crowd are "slim, almost impossible."
