Kluber to miss 10 days with hamstring injury

The Cleveland Indians received bad news Friday that will affect their chances of staying alive in the American League wild-card race.

Cy Young Award winner Corey Kluber will miss at least 10 days, according to manager Terry Francona.

"He's going to be down for I'd say a minimum of 10 days," Francona told reporters. "Rather than put too much of a timetable on it, when he's ready, we'll pitch him. That's kind of where we are there."

The Indians scratched the 29-year-old from Friday's start against the Detroit Tigers because of a strained right hamstring, which Francona said he injured while throwing a bullpen session.

"He went and conditioned, and probably exacerbated it a little bit," Francona said. "I still think he thought he was going to pitch. The more the trainers looked at him, we had the day off (on Thursday), (so we) thought, 'OK, let's get him back to Cleveland, get him looked at.'"

Josh Tomlin will instead make the start for the Indians, whose rotation is already without right-hander Carlos Carrasco, who is currently on the 15-day disabled list with a right shoulder issue.

Kluber leads the league with 200 1/3 innings pitched and four complete games, with a 3.41 ERA and 1.03 WHIP.

Cleveland sits six games back of the Texas Rangers for a wild-card spot.
