Maria Sharapova has advanced to the Wimbledon quarterfinals by beating Peng Shuai of China 6-4, 6-2.
The fifth-seeded Russian, who won the 2004 title at the All England Club, broke for the first time to take a 5-4 lead in the first set Monday. From that break, she won seven straight games to take control.
Sharapova has also won the U.S. Open and Australian Open, but has only recently returned to top form after shoulder surgery in 2008.
Sharapova will next face either Dominika Cibulkova in the quarter-final round.
