Veteran right-hander Trevor Rosenthal is slated undergo elbow surgery next week, the Tigers announced within their latest wave of injury updates on minor league players. The former All-Star has been attempting a comeback with the Tigers, but he’s now headed for a revision on a prior Tommy John procedure. Detroit also announced that infielder Ryan Kreidler underwent core muscle surgery and that lefty Miguel Del Pozo had Tommy John surgery.
Rosenthal, 33, hasn’t pitched in the Majors since the 2020 season and has just 39 big league frames under his belt since the conclusion of the 2017 season. Injuries have derailed the career of the former Cardinals closer, who underwent Tommy John surgery in 2017 and thoracic outlet surgery in 2021. Rosenthal also had surgery to repair a torn labrum in his hip during the 2021 season.
A healthy Rosenthal has proven himself capable of being one of the sport’s top relievers. From 2012-15, he boasted a 2.66 ERA and 30.4% strikeout rate, twice reaching 45 saves in a season along the way. His 2019 return from that 2017 Tommy John procedure was a disaster, but Rosenthal pitched 23 2/3 innings of 1.90 ERA ball while punching out 41.8% of his opponents during the shortened 2020 season. This will now be Rosenthal’s third surgery of note since his last big league pitch, however. He pitched in just three minor league games with the Tigers this year before landing on the injured list.
Kreidler, 25, has appeared in 37 games for the Tigers dating back to 2022 but has just a .165/.220/.209 slash in 102 big league plate appearances. He’s slashed .253/.374/.466 with 18 home runs and 22 steals through 446 plate appearances at the Triple-A level in his career, however, and is regarded as an above-average defender who can handle multiple spots around the infield (third base, shortstop and second base). He’s currently in physical therapy following the surgery. A timetable for his return wasn’t provided.
The 30-year-old Del Pozo returned to the Tigers on a minor league deal this offseason. He’d previously pitched 5 1/3 frames as a Tiger back in 2021 and also spent the 2022 season in their Triple-A bullpen, pitching to a 3.88 ERA in 53 1/3 frames. Del Pozo, who’s allowed 20 runs in 18 1/3 big league innings but has a more palatable 4.23 ERA in four Triple-A campaigns, appeared in just six games this season before landing on the injured list. The timing of this surgery will shelve him until late in the 2024 season and potentially all the way into the 2025 season.
