Hammy hobbles Raonic again
Milos Raonic has pulled out of the Miami Open after aggravating a right hamstring injury that sidelined him for nearly a month. The No. 3-seeded Raonic withdrew before Sunday’s match against American qualifier Jared Donaldson, who advanced to the fourth round. Raonic said his injury became progressively worse after his opening match, his first since Feb. 25. He expects to be sidelined at least two weeks and perhaps longer. The Canadian said he hasn’t made it through an entire tournament healthy since Wimbledon last July.
