Raonic withdraws from Miami Open with injury

INJURY-PLAGUED world No5 Milos Raonic pulled out of the Miami Open on Sunday with a recurrence of a hamstring injury, leaving the Canadian star saying he would not return until he is 100 percent fit. Raonic originally suffered the injury in the semifinal at Delray Beach and was forced to forfeit the final against Jack Sock of the US. He then missed this month’s Masters event at Indian Wells. The 26-year-old returned to action in Miami on Friday with a win over Serbian Viktor Troicki but said his injury had flared up again. “After practising [on Saturday], it was not possible to compete without putting myself at significant risk,” he said.
