Marlins place lefty reliever on 15-day injured list

The Marlins are placing A.J. Puk on the 15-day injured list, as the left-hander is dealing with some nerve irritation in his left elbow.  A corresponding move hasn’t yet been announced and it might not come until Tuesday, since Miami has an off day on Monday.  Jordan McPherson of the Miami Herald (Twitter link) guesses that JT Chargois might replace Puk, as Chargois is completing a rehab assignment after missing just over a month with an oblique strain.

Puk’s last appearance was on May 10, and manager Skip Schumaker told the Herald’s Andre Fernandez and other reporters prior to today’s game that Puk had been dealing with a “dead arm.”  The designation of nerve irritation sheds some new and concerning light on the issue, as while it could be that Puk might be back to normal after 15 days, there is no real timeline for nerve-related injuries.

It’s another troubling injury setback for Puk, as Tommy John surgery cost him all of the 2018 season as a prospect in the Athletics’ farm system, and he didn’t pitch in 2020 due to shoulder problems that eventually required surgery.  Puk carried a lot of promise as a starter on his way up the minor league ladder, yet his health problems led the A’s to use him only as a reliever. In his first full MLB season, Puk looked mostly excellent in posting a 3.12 ERA over 66 1/3 relief innings for the A’s in 2022.

That good form has continued into Puk’s first year in Miami, as the Marlins dealt JJ Bleday (another former top prospect) to Oakland for Puk back in February. Though the Marlins considered using Puk as a starter, they instead opted to use him as their primary closer, with strong results. Puk has a 3.07 ERA and a wealth of impressive secondary metrics over 14 2/3 innings with the Marlins, including a 29.2% strikeout rate and 4.6% walk rate which are both well above the league average.  Batters haven’t been able to make much hard contact against Puk’s offerings, as his 2.4% barrel rate is among the best in MLB.

Dylan Floro got the save in Sunday’s 3-1 win over the Reds, and he is likely the favorite for ninth-inning work in Puk’s absence given how Floro finished the 2020 season as Miami’s closer. The Marlins could also take a situational approach to save situations, with any of Floro, Andrew Nardi, Huascar Brazoban, Tanner Scott, or Matt Barnes getting a crack at closer duties based on in-game scenarios.

It’s been a tough couple of days health-wise for the Marlins, as while Garrett Cooper returned from the 10-day IL Sunday, Miami has lost both Jesus Sanchez and now Puk to the injured list. Jazz Chisholm Jr.’s status is also to be determined, as Schumaker said the center fielder will visit a specialist about a case of turf toe. Chisholm suffered the injury in Saturday’s game after a collision with the outfield wall in pursuit of a fly ball.
