Red Sox’ Kutter Crawford leaves game with left hamstring tightness

Red Sox reliever Kutter Crawford left the ninth inning of Wednesday night’s 8-3 win over the Blue Jays with left hamstring tightness, the club announced.

Crawford entered Wednesday’s contest in the top of the eighth. The right-hander yielded a two-out single and walk before getting Daulton Varsho to ground out to escape the jam. He then came back out for the ninth and got leadoff man Alejandro Kirk to ground out to second base on the 12th pitch of a lengthy at-bat.

After retiring Kirk, it became clear that Crawford — who was pitching in cold and rainy conditions at Fenway Park — was in discomfort as he flexed and grabbed at his left hamstring. That prompted Red Sox manager Alex Cora and head athletic trainer Brandon Henry to emerge from the home dugout and check up on him.

Following a brief conference on the mound, Crawford departed with Henry and was replaced by Ryan Brasier, who recorded the final two outs of the game. When speaking with reporters (including MassLive.com’s Chris Cotillo) shortly thereafter, Cora indicated that the Red Sox would know more about Crawford’s condition on Thursday.

“We’ll know probably, tomorrow, what’s going on,” said Cora.

Crawford, 27, opened the 2023 season in Boston’s starting rotation but has since emerged as a valuable multi-inning reliever out of the bullpen alongside Josh Winckowski. After being called back up from Triple-A Worcester on April 13, the hard-throwing righty came into play Wednesday having posted a 1.17 ERA and 3.50 FIP with 12 strikeouts to zero walks over four relief appearances spanning 15 innings of work.

As noted by Cotillo, the Red Sox already have five pitchers on the injured list in Zack Kelly, Wyatt Mills, James Paxton, Joely Rodriguez, and Garrett Whitlock. All three of Paxton, Rodriguez, and Whitlock are on the verge of returning to action, though.
