CLEVELAND -- Indians relief ace Andrew Miller left Wednesday's 4-1 win over the Chicago Cubs because of left hamstring tightness.
Miller is set for an MRI on Thursday, and manager Terry Francona said the lefty had the same injury while pitching for Baltimore in 2014.
"He's had it before,'' Francona said. "The hope is, I think last time he said it was 3-4 days. That would really be the hope. We'll know a lot more tomorrow. And hopefully, that's all it is.''
Miller relieved Trevor Bauer with Cleveland leading 3-1 in the seventh inning.
The left-hander fell behind 2-0 to Anthony Rizzo then grabbed his left leg and walked around the mound.
Francona and a team trainer went to the mound before Miller walked to the dugout. The team announced the diagnosis during the eighth inning.
Miller hasn't given up a run in 10 innings this year.
