Jack Sock claimed his second ATP title of 2017 on Sunday as top-seeded Milos Raonic withdrew before the Delray Beach Open final with a torn hamstring.
Canada’s Raonic, ranked fourth in the world, was playing his first tournament since suffering his fourth adductor muscle injury in 12 months at the Australian Open in January.
Raonic told the Tennis Channel he was hurt in a semi-final win over former US Open champion Juan Martin Del Potro on Saturday night.
“I didn’t think much of it,” Raonic said. “I thought it was just tightness from the match, but this morning I woke up unable to walk properly and did quite extensive treatment with my team.
