DETROIT -- Cleveland Indians ace Corey Kluber left Monday night's 7-4 win over the Detroit Tigers after only four innings because of right groin tightness.
Kluber threw only 60 pitches and left with the Indians leading 4-2.
The Indians, who clinched the AL Central title with the victory, already are dealing with injuries to starters Carlos Carrasco and Danny Salazar, and a serious injury to Kluber would further hamper the team's chances at an extended postseason run.
Kluber allowed two runs and five hits. He gave up a two-run homer to J.D. Martinez in the second inning but got out of a bases-loaded, one-out jam in the fourth.
The Indians took the lead with two runs in the top of the fifth, then reliever Dan Otero came to the mound for Cleveland.
