Gerrit Cole left the New York Yankees' loss to the Toronto Blue Jays with two outs in the fourth inning on Tuesday night because of tightness in his left hamstring.
Cole was pulled after allowing a sacrifice fly to Reese McGuire that gave Toronto a 3-1 lead.
Aaron Boone provided a bit of optimism for his team in his postgame availability, saying there is no MRI scheduled on Cole's hamstring and that the Yankees feel like they caught on to his issue early in the process.
"Right now, he's just experiencing some tightness, so we'll kind of see where we're at," Boone said. "I know in talking to Gerrit he feels pretty optimistic about it. It's something that's popped up before with him on other pitches."
Cole allowed three runs, two of them earned, and five hits in 3 2/3 innings.
