Willson Contreras (hamstring) placed on IL; Red Sox recall Gasper

Willson Contreras is heading to the injured list with a hamstring injury, the Red Sox announced, with the club recalling Gasper — described as hot-hitting — from the minors to fill the roster spot.

Per Ian Browne of MLB.com, Contreras had been managing the hamstring issue for weeks before the organization made the move official, placing him on the 10-day IL with a left hamstring strain. The timing is notable: Boston is navigating a stretch run with roster depth already in flux.

What we don't know yet

No timetable for Contreras's return appears in the material. The nature of hamstring injuries and the fact that he had been managing it for some time are the only details available — anything beyond that remains unconfirmed.

The bigger picture

The Contreras move lands in the middle of a busy stretch of Red Sox roster activity. Roman Anthony and Trevor Story were both activated off the injured list around the same period, and the club has been adjusting rotation usage by giving Sonny Gray extra rest ahead of the stretch run. Boston is clearly trying to calibrate who is available and who is healthy as September approaches.

Gasper's recall gives the club a fresh option behind the plate while Contreras works through the injury. Whether that arrangement holds through the stretch run depends entirely on how quickly Contreras responds — and that part remains an open question.
