If Maria Sharapova wants to claim the world's top ranking at the German Open, she might have to beat some pretty tough competition. Sharapova needs to win the tournament to unseat Lindsay Davenport at No. 1. On Wednesday, the 18-year-old Russian breezed past Anna-Lena Groenefeld of Germany 6-2, 6-2. Sharapova next faces Shuai Peng of China in the third round Thursday.
