A pair of injured Tigers faced off in live batting practice yesterday, highlighting their progress towards returning to action. Outfielder Kerry Carpenter and right-hander Casey Mize both looked good during the session, which included a long home run and a single off Mize by Carpenter.
Carpenter, 27 in September, has been on the IL since May due to a lumbar spine stress fracture. He was in the midst of an incredible season when he hit the shelf, slashing a fantastic .283/.347/.572 with 10 doubles, four triples, and eight home runs in just 50 games. That performance was good enough for an excellent wRC+ of 149, and Carpenter’s return from the shelf should provide a big boost to the Tigers lineup down the stretch even as they’ve largely fallen out of playoff contention at this point. That return could be just over the horizon, as Carpenter told reporters (including Chris McCoskey of The Detroit News) yesterday that he’ll “probably” be starting a rehab assignment sometime this week. With both Carpenter and Riley Greene on the IL at the moment, the Tigers are currently relying on an outfield of Matt Vierling, Wenceel Perez, and Parker Meadows.
Despite the damage dealt by Carpenter, Mize also reportedly looked good during his two innings of work yesterday. As noted by MLB.com’s Injury Tracker, Greene (who also faced Mize yesterday) told reporters that the right-hander looked good and threw all of his pitches with confidence during the outing. Mize, who has been on the shelf for just over a month now due a hamstring strain, won’t be eligible to return from the 60-day IL until August 31 but could begin a rehab assignment of his own at some point in the near future as he builds back up towards MLB action. Mize’s 16 starts this year have been something of a mixed bag with a league average 4.23 ERA but a much stronger 3.69 FIP in 78 2/3 innings of work, though getting on the field at all was a meaningful step for the first overall pick of the 2018 draft after he made just two starts in 2022 and missed the whole 2023 campaign due to Tommy John surgery.
Mize’s eventual return to the rotation for the Tigers is sure to be a welcome one given the relatively dire situation the club’s starting staff has found itself in recently. After the club dealt Jack Flaherty to the Dodgers at the deadline and saw Reese Olson join Mize on the shelf due to shoulder strain late last month, the club is facing plenty of uncertainty behind ace Tarik Skubal. Rookies Bryan Sammons and Keider Montero have struggled to ERAs north of 5.00 and 6.00 respectively as fill-in starters this year while veteran righty Kenta Maeda had a 7.26 ERA in 16 starts before being moved to the bullpen just before the All-Star break.
Maeda has pitched somewhat better since moving to the bullpen, with a 4.40 ERA and a stronger 4.14 FIP in 14 1/3 innings of work across four appearances. As noted by Evan Petzold of the Detroit Free Press, manager A.J. Hinch recently told reporters that while the club expects the veteran to rejoin the rotation proper at some point, their current plan is to keep him in the bullpen for the time being while trying to get him “regular work that’s similar to a starting pitcher.” So far, that’s seemed to mean using Maeda as a bulk arm following an opener while mostly keeping him on a starting pitcher’s schedule. The Tigers are surely hoping that the 36-year-old can get right in the final months of the 2024 season as they look ahead to the final year of his two-year, $24MM contract in 2025.
