In the players’ lounge just before Andy Murray’s withdrawal from the Rogers Cup became official, Milos Raonic bumped into the men’s Olympic tennis champion, whom he was scheduled to play in Thursday night’s featured match.The irony was not lost on either player. In March, after spraining his ankle in the warm-up of a doubles match at the Sony Ericsson tournament in Miami, Raonic had to withdraw in the round of 32, giving Murray a walkover. Five months later, Murray returned the favour.“I sort of asked him, is he going to be okay and everything,” Raonic said. “I guess we made a joke because I pulled out earlier to him in Miami this year, so it was joke about that. I just wished him that he gets healthy quick, because he’s been playing really well lately.”
