The 27-year-old Russian has now beaten the talented Canadian 20-year-old in each of their four meetings, three of which have been at grand slams.

The second seed jumped on a clearly nervous Bouchard in the first game of the match by breaking serve and not allowing her opponent to settle.

The early setback affected the Canadian's timing as she made 20 unforced errors, before Sharapova broke again in the ninth game to take the first set in 41 minutes.

The five-times grand slam winner made another fast start in the second set, racing through her first service game and breaking in the fourth to give her the opening needed to set up a semi-final against 10th-seeded compatriot Ekaterina Makarova.
