Maria Sharapova reaches the quarter-finals of the China Open

World number two and second seed Maria Sharapova made easy work of Slovenian Polona Hercog to reach the quarter-finals of the China Open.

The Russian won 6-0 6-2 in just over an hour against the world number 90 and is yet to drop a set in the tournament.

She will now face either Caroline Wozniacki or Angelique Kerber in the last eight, with that pair set to meet later on Thursday.

In the men's draw Russia's Mikhail Youzhny beat Kevin Anderson 6-3 6-3.
