LONDON (Reuters) - Maria Sharapova dispatched Klara Zakopalova 6-2 6-3 to reach the Wimbledon fourth round on Saturday.

The Russian fifth seed looked more assured than in Friday's scrappy win over 17-year-old Briton Laura Robson, blasting a succession of winners past her Czech opponent to take the first set.

Sharapova, Wimbledon champion in 2004, lost concentration at the start of the second as Zakopalova opened up a 3-1 lead but the 24-year-old refused to cave in and stormed back before sealing victory with a thundering forehand winner.
