Miami (AFP) - Injury-plagued world No. 5 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 semi-final at Delray Beach and was forced to forfeit the final against American Jack Sock. 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.
"It is the same muscle in the hamstring it got progressively worse after my first round and after practising yesterday (Saturday), it was not possible to compete today without putting myself at significant risk,” he told reporters.
Raonic was due to face American qualifier Jared Donaldson.
Raonic has struggled with injuries for several months and said he had not been 100 percent fully fit for a tournament since last year’s Wimbledon where he reached the final, before losing to Andy Murray.
"It hasn't been fun the last seven months. I haven't played one tournament form start to finish healthy. My goal for this tournament was to at least finish it healthy."
After Wimbledon, Raonic was hampered by cramps at the U.S. Open and the same issue caused him to miss Canada’s Davis Cup match with Chile in September.
A month later, he withdrew from the China Open before his scheduled semi-final due to an ankle injury and he had to pull out a semi-final at the Paris Masters in November with a quadriceps tear.
Looking ahead to the clay court season, Raonic said that he was not going to play again until he was fully fit.

"Right now the perspective is going to change a little bit. Obviously the goal through these tournaments being on hard courts and so forth was that I can come back as soon as I feel ready.
"I think that that perspective is going to change to come back when I feel like I'm 100 percent. So I think that will -- so that could be -- who knows how long? That could be in two weeks; that could be a little bit longer,” he said.
Raonic said he has been looking at possible changes to his training routines to try and avoid further injury problems.
"We've been trying a lot of different things, how many days in a row I'll train to the kind of exercises I'll do and so forth.
"I've been able to get through practices and training sessions where you push and push I would say physically-wise they are harder than matches. But I think in matches you sort of take out any kind of caution and you just go out and compete.
"That's where the issues have been coming. I haven't been having issues of getting hurt in practices and so forth. It's about really finding maybe new methods and approaches just to keep myself or get myself as prepared to withstand any kind of strain on my body."
