Will start Saturday
Manager A.J. Hinch said Friday that Mize (thigh) will start Saturday's game against the Blue Jays, Cody Stavenhagen of The Athletic reports.
Analysis
Mize landed on the injured list after he sustained a right adductor strain in an April 28 start against Atlanta. The right-hander has logged a 2.90 ERA, 1.19 WHIP and 35:11 K:BB across 31 innings this season. Mize has a career-high 27.3 percent strikeout rate across his first six starts.

Could return to start Saturday
Mize (thigh) could return from the 15-day injured list to start Saturday's game against the Blue Jays, Chris McCosky of The Detroit News reports.
Analysis
Mize has been sidelined since late April with a right adductor strain. He has not made a rehab start, but the right-hander threw a live batting practice session earlier this week and it appears he could skip a rehab assignment. Mize was excellent in his first six outings this season before getting hurt, posting a 2.90 ERA and 35:11 K:BB over 31 innings. If Mize is able to start Saturday, he figures to be somewhat limited from a pitch-count perspective.

Faces hitters Monday
Mize (thigh) threw live batting practice Monday, Cody Stavenhagen of The Athletic reports.
Analysis
Mize began throwing bullpen sessions over the weekend, and his quick return to facing live hitters keeps him on track for a brief stay on the injured list. The 29-year-old righty will be eligible to return from his right calf strain Thursday.

Completes side session
Mize (adductor) threw a bullpen session Friday, MLB.com reports.
Analysis
Mize appears to be tracking toward an abbreviated stay on the injured list while he works his way back from a mild right adductor strain, but he may not be ready for activation when first eligible in the middle of next week. He'll still need to face hitters in a simulated game or minor-league rehab assignment before Detroit brings him back from the IL.
