DETROIT — Casey Mize, off to the best start of his career, will have to hit pause.

Detroit Tigers manager AJ Hinch announced before the game Saturday that Mize was placed on the 15-day injured list dating to Friday with a mild left hamstring strain.

“In his last inning in Colorado (Thursday), he felt a sensation or a tweak and everybody thought it was dehydration,” Hinch said. “Turns out, it was a little something (in the hamstring). It’s very mild but he probably wasn’t going to make his next start on Tuesday.

“That puts us in a tough spot with how long to carry the unknown.”

The Tigers called up reliever Chase Lee from Triple-A Toledo in the short-term. The club will list its starter for Tuesday as TBD for now, but Keider Montero, who went eight innings in Colorado in Game 2 Thursday, would be on track to pitch.

“It’s May,” Hinch said. “We’re certainly going to be careful with that. But we expect Casey to be fine in a short period of time.”

The worry is, Mize strained the same hamstring late last June and he ended up missing two months. It’s the same hamstring, but Hinch indicated it wasn’t the same type of strain.

Mize in his first seven starts has posted an MLB-best six wins with a 2.53 ERA, 1.008 WHIP, 21% strikeout rate and 5% walk rate.
