MIze (adductor) won't be activated from the 15-day injured list to start Sunday against the Guardians after the game was postponed due to inclement weather in Cleveland.
The two teams will make up the game as part of a split doubleheader Sept. 4. After making a five-inning rehab start with Single-A Lakeland earlier in the week, Mize had been slated to make his first appearance for Detroit since May 27. Due to the postponement, however, the Tigers will push Mize's return back three days, with the right-hander now scheduled to be activated from the IL to start Wednesday in Houston, per Jason Beck of MLB.com.

Tigers' Casey Mize: Rehab start slated for Tuesday
Rotowire
Mize (adductor) will make a rehab start with Single-A Lakeland on Tuesday, Evan Woodbery of MLive.com reports.
Mize landed on the 15-day injured list May 29 due to right adductor inflammation, but he doesn't appear to be headed for an extended stint on the shelf. After tossing a successful bullpen session Tuesday, Mize will now likely need just one rehab start before receiving the green light to rejoin the Detroit rotation. He could be a candidate to start for the Tigers as soon as next Sunday in Cleveland.

Tigers' Casey Mize: Trending toward short IL stint
Rotowire
Mize (adductor) tossed a bullpen session Tuesday, Chris McCosky of The Detroit News reports.
Detroit placed Mize on the 15-day injured list Friday due to right adductor inflammation, but his ability to step back on the mound just a few days later suggests that he's tracking toward an abbreviated stint on the shelf. The Tigers haven't decided on Mize's next steps, but assuming he bounces back well from the side session, he'll likely advance to facing hitters by the weekend. He's eligible to return from the IL on June 12 and could be activated without requiring a rehab assignment beforehand.

Tigers' Casey Mize: Lands on injured list
Rotowire
The Tigers placed Mize on the 15-day injured list Friday with right adductor inflammation, retroactive to Thursday.
Mize left his start against the Angels on Wednesday with groin tightness, and although an MRI didn't reveal a strain, he'll still end up on the injured list while the Tigers treat his inflammation. Beau Brieske (thigh) was activated from the 60-day IL in a corresponding move, though it remains unknown who will take Mize's place in Detroit's rotation.

Tigers' Casey Mize: Takes tough-luck loss Thursday
Rotowire
Mize (2-3) allowed two runs on four hits across 6.2 innings and took the loss in Thursday's 3-1 defeat to the Guardians. He struck out four and didn't walk anyone.
Making his second start after missing a few weeks due to an adductor strain, Mize pitched well once again but got little run support and was outdueled by Joey Cantillo and the Cleveland bullpen. While he doesn't have the wins to show for it yet, Mize has been sharp this year with a 2.47 ERA, 0.98 WHIP and 43 strikeouts in 43.2 innings across eight starts. The righty will look to keep up his strong play in his next outing, which should come against the Angels at home next week.

Tigers' Casey Mize: Activated ahead of start
Rotowire
The Tigers reinstated Mize (thigh) from the injured list Saturday.
Mize landed on the injured list in late April with a right adductor strain, but he'll now make his return without a rehab assignment and take on a Blue Jays squad that's posted just a .675 OPS since the beginning of the month. Brenan Hanifee was optioned to Triple-A Toledo to make room for Mize on the active roster.

Tigers' Casey Mize: Completes side session
Rotowire
Mize (adductor) threw a bullpen session Friday, MLB.com reports.
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.

Tigers' Casey Mize: Lands on IL with adductor strain
Rotowire
The Tigers placed Mize on the 15-day injured list Wednesday due to a right adductor strain.
After exiting midway through the third inning of his start Tuesday against Atlanta due to a tight groin, Mize was diagnosed with the adductor strain following an MRI on Wednesday. According to Chris McCosky of The Detroit News, Mize's strain is of the Grade 1 variety, offering hope that the right-hander may be ready to able to return from the IL in close to the minimum amount of time. Justin Verlander (hip) has been ramping up his throwing program and could eventually beat Mize back from the IL to claim the open spot in the rotation, but the Tigers may have to turn to Sawyer Gipson-Long or Drew Anderson to make a spot start when Mize's turn comes up Sunday versus the Rangers.

The 28-year-old has now allowed one earned run or fewer in three of four starts, with the lone exception being a five-run clunker April 6.

Tigers' Casey Mize: Surrenders five runs in loss
Rotowire
Mize (0-1) took the loss Monday, allowing five runs on seven hits and three walks over 4.1 innings against Minnesota. He struck out four.
Mize didn't have his best stuff Monday, as a lengthy third inning and a two-run homer from Luke Keaschall in the fourth frame did damage. It marked a step back for the right-hander after a strong first start against Arizona, in which he fired six innings of one-run ball with nine punchouts. Looking ahead, Mize lines up to face Miami on Saturday in his next outing.

Tigers' Casey Mize: Punches out nine in quality start
Rotowire
Mize did not factor into the decision Tuesday, striking out nine and allowing one run on four hits and two walks over six innings during a 7-5 loss to the Diamondbacks.
Mize induced 15 swinging strikes on 93 pitches as he limited Arizona to a solo homer across six frames, but he lost out on the victory due to an eighth-inning collapse by the Detroit bullpen. The right-hander has never been a big punchout guy with a career 19.5 percent strikeout rate, but his splitter was in top form Tuesday, generating nine whiffs and six strikeouts. Mize lines up for a favorable road matchup against the Twins early next week.

Tigers' Casey Mize: Hit hard Friday
Rotowire
Mize allowed six runs on six hits and four walks across three innings in Friday's Grapefruit League contest against the Pirates. He struck out two.
This was easily Mize's worst start of the spring slate, as he came into the contest having allowed three total earned runs across 8.1 Grapefruit League innings. He said after the contest that his "mechanics are off," per Jason Beck of MLB.com, which is somewhat concerning at this point during spring training. The righty should still be locked into a regular-season rotation spot, though the Tigers did bolster their pitching staff in the offseason with the additions of Framber Valdez and Justin Verlander, so Mize may be knocked down the pecking order a bit. He stayed mostly healthy last year and posted a 3.87 ERA, 1.27 WHIP and 139 strikeouts across 149 regular-season innings.

Tigers' Casey Mize: Starting Game 4, if needed
Rotowire
Mize will draw the start on the mound in Wednesday's Game 4 matchup with Seattle, if needed, Ryan Divish of The Seattle Times reports.
Mize will toe the rubber for the second time in the postseason if the Tigers' series against Seattle in the ALDS reaches a Game 4 on Wednesday. The right-hander pitched three innings, allowing one run on one hit and two walks while striking out a batter in the team's 6-1 loss to the Guardians in Game 2 of the wild-card round. Mize will look to last longer in his next outing, whether it comes Wednesday or later down the road in the playoffs.

Tigers' Casey Mize: Short Game 2 outing
Rotowire
Mize took a no-decision in Wednesday's game versus the Guardians, allowing one run on one hit and two walks over three-plus innings.
The only hit and run Mize surrendered came courtesy of George Valera, who cranked a solo home run in the bottom of the first inning. Mize struck out just one batter, though, and had thrown 62 pitches when he was lifted after issuing a leadoff walk in the bottom of the fourth inning. The right-hander should get another start if the Tigers advance to the ALDS, but manager A.J. Hinch would likely have a quick hook again.

Rotowire
Mize did not factor into the decision in Friday's 4-3 loss at Boston, allowing two runs on six hits while striking out eight over 6.1 innings. He did not issue a walk.
The Detroit right-hander ended his regular season on a high note, generating 14 whiffs out of his 80 total pitches to notch his ninth quality start. Mize tallied five or more strikeouts for the fifth time out of 28 total starts. The Auburn product contained the Red Sox's lineup, with the only runs he allowed scoring on single in the fourth and a sacrifice fly in the seventh. Mize finishes with a 3.87 ERA, 1.27 WHIP and 139:36 K:BB across 149 total innings.
