Marlins near a potential return for Eury Pérez, pitching work next on the list

The Marlins appear to be closing in on the kind of roster reset that can stabilize a rotation midseason. According to MLB Trade Rumors, right-hander Eury Pérez is approaching a return from the 15-day injured list, with a timeline that could line up for his next major-league start as soon as next week.

Pérez’s recent progress came during a rehab assignment with Triple-A Jacksonville. MLB Trade Rumors reported that the 6-foot-8 starter threw 3 2/3 innings and logged 51 pitches in that outing. The performance is being treated as a meaningful checkpoint because it suggests he is capable of handling live innings volume again, not just movement work.

Manager Clayton McCullough, speaking to reporters including Christina De Nicola and Shanthi Sepe-Chepuru of, indicated that Pérez’s next scheduled task is a pitch design session. In practical terms, that kind of bullpen-and-approach workout is often used to map how a pitcher intends to attack hitters once he is back in game situations, including which pitches are featured, how they are sequenced, and how the repertoire is expected to shape up over multiple turns through a lineup.

MLB Trade Rumors also described the possibility that Pérez might not need another minor-league start before joining the Miami rotation. That detail matters because it points to the Marlins viewing the most recent rehab outing as sufficient for the next phase. Teams commonly require additional work if a pitcher runs short on pitch count, struggles with command, or needs more time building stamina, so the indication here is that Pérez is tracking well.

For a staff that has to manage workloads and maintain consistency, the difference between “one more rehab start” and “next week, next rotation” is significant. A pitcher returning sooner can prevent innings from spilling into less dependable roles, such as longer bullpen stints or forced shuffle days for other starters. It also can change how a team sequences matchups across a stretch, since managers tend to plan around their most reliable arms.

Still, the update is not a formal guarantee of a specific reactivation date, and the nature of injury recoveries means small setbacks can alter timelines quickly. The Marlins’ immediate focus, based on the reporting, is the pitch design session and ensuring Pérez’s readiness lines up with what he is expected to do once he is again part of the major-league rotation. If that work goes smoothly, the next milestone would be an actual start that confirms his durability over a full rotation assignment.
