Maria Sharapova eases through at Wimbledon

Maria Sharapova has blasted her way into the fourth round of Wimbledon with a straight-sets win over the USA's Alison Riske.

Riske surprised the Centre Court crown by breaking at the start of the opening set, but Sharapova fought back soon after to claim it 6-3.

The Russian then carried her impressive form into the second as three breaks of serve allowed her to serve out the one-sided encounter 6-3 6-0 in just over an hour.

Sharapova will now face either ninth seed Angelique Kerber or 24th seed Kirsten Flipkens for a quarter-final berth.
