Canadian Milos Raonic, who is the No. 16 seed at the Roger Cup in Toronto, says he has a chance to accomplish big things this week. Raonic opens against Victor Troicki tonight and could face Olympic gold medalist Andy Murray in the third round. "It’s a big opportunity I really look forward to. Here is where I can make the most difference, not only for myself and my tennis, but also in Canadian tennis and tennis in the public eye — maybe just outside one of the Grand Slams," Raonic told reporters. "Really, it’s a very special event."
