Pete Sampras believes Raonic is already a threat amongst the higher-ranked pros

14-time Grand Slam champion Pete Sampras said that he sees Milos Raonic as a force to be reckoned with at the ATP Tour.

The American legend was in Toronto last week for a Legends Cup exhibition event with fellow legends Jim Courier and John McEnroe. Sampras believes that Raonic, currently ranked tenth in the world following his run to the Montreal Masters final, is already due to for a breakthrough on tour.

“He’s up against (Novak) Djokovic and (Andy) Murray and Roger (Federer) and four great players, and it takes time,” said Sampras. “I think he’s a threat already. I think he’s got a huge game, monster serve, willing to come in and do some things and get to the net.”
