Raonic’s serve was working once again in the one-hour, 18-minute match, as he fired 14 aces and never faced a break point.
The victory is his 31st in 2011, adding to a season total that is already the best ever produced by a male Canadian singles player.
The 20-year-old reaches his fourth ATP World Tour semifinal of the season and will next take on the winner of No. 1 seed Gael Monfils against No. 5 Kevin Anderson, who play later today.
Raonic has never played Monfils, though he was scheduled to face him in the semifinals of the SAP Open in San Jose in February. He received a walkover when the Frenchman withdrew, and went on to win the title, his first ATP World Tour crown. Should he play Monfils, it could be a preview of next February’s World Group first-round tie between Canada and France.
It would also be his first meeting with Anderson, the big-serving South African.
