Maria's sneak preview

Wimbledon champion Maria Sharapova and world No. 2 Andy Roddick were among the superstars to hit Melbourne Park shortly after arriving yesterday.
Sharapova chose an outside court far away from prying eyes to engage in a series of reflex-sharpening exercises with balls of all sizes under the instructions of her fitness coach.

The Russian blonde demonstrated the nimble footwork that she hopes will carry her through two weeks of heat and seven opponents to a first Australian title.
