The Detroit Tigers placed right-hander Casey Mize on the 15-day injured list May 10 with a left hamstring strain — the same injury that sidelined him for two months last season.
It's a "mild strain," according to manager A.J. Hinch.

The placement on the injured list is retroactive to May 9, making Mize eligible to return as soon as May 24. The Tigers have yet to name a starting pitcher for their May 13 game against the Boston Red Sox at Comerica Park.
"In his last inning in Colorado, he felt a little sensation, tweak, whatever that is," Hinch said, referencing Mize's May 8 start against the Rockies at Coors Field in Denver. "Everybody thought dehydration. Turns out, it was a little something — very mild."

To fill Mize's roster spot, the Tigers recalled right-handed reliever Chase Lee from Triple-A Toledo. For the May 13 game, the Tigers could option Lee back to Toledo and call up a starter from the Mud Hens, potentially right-hander Keider Montero.
"He probably wasn't going to start on Tuesday, which puts us in a tough spot of how long to carry the unknown," Hinch said of Mize. "In May, we're certainly going to be careful with that, but we expect it to be fine in a short period of time."
Montero, 24, didn't make the Opening Day roster, but he has already started four games for the Tigers, posting a 4.15 ERA with 10 walks and 15 strikeouts across 21⅔ innings.
For now, though, Montero remains at Triple-A Toledo.

The loss of Mize costs the Tigers one of their top four starting pitchers. The 28-year-old has a 2.53 ERA with nine walks and 35 strikeouts across 42⅔ innings in seven starts.
It's unclear if Mize — the 2018 No. 1 overall pick — will need a rehab assignment as part of his recovery from the left hamstring strain, though he made four rehab starts after suffering a left hamstring strain last season.

The good news: Hinch said there's no connection between last year's injury and this year's injury.
"It's a big hamstring," Hinch said.
