Maria Sharapova, the 17-year-old Russian needed just over an hour to overpower Miho Saek and advanced to the quarterfinals of the Korea Open beating Miho 6-3, 6-1.

Miho Saeki took a 3-1 lead in the first set, moving Sharapova around the court with some well-placed backhands and deft drop shots. But the Siberian teenager's strength became the decisive factor and Saeki only took one more game in the match.

The top-seeded Russian will face Samantha Stosur, who beat Galina Voskoboeva 6-2, 6-4 on Wednesday.
