We already have an upset at the 2010 Australian Open. It took three achingly long hours, but Maria Kirilenko defeated countrywoman Maria Sharapova 7-6, 3-6, 5-4 in the first round. Dressed for late-night dancing in Hawaii rather than competitive tennis, Maria Sharapova never got comfortable as she struggled with her serve and stumbled around the court. After overcoming a shoulder injury, we expected Sharapova to arrive reinvigorated and close to top form. During her loss against Kirilenko, however, it’s obvious that something is simply wrong with her game.

As for Kirilenko, this is one of the biggest victories of her career. The women’s draw at this tournament is loaded with decorated players, but that shouldn’t frighten Kirilenko. Given her performance in this match, she should give any of them a run for their money.
