Mets activate Justin Hagenman from 60-day IL; righty set to start Wednesday vs. Rays

What happened

The New York Mets reinstated right-hander Justin Hagenman from the 60-day injured list ahead of Wednesday's matchup at Tampa Bay, per a club announcement. Per that announcement, Hagenman is expected to draw the start against the Rays at Tropicana Field, where Griffin Jax is projected to start on the other side.

To clear a spot on the active roster, the Mets returned right-hander Dylan Ross to Triple-A Syracuse. Hagenman's reinstatement also filled the last remaining opening on New York's 40-man roster, per the announcement.

Why it matters

Hagenman's return closes a chapter that began in spring training, when a fractured rib cost him more than four months of the season. That kind of absence — stretching from the spring all the way into September — tends to reshape a pitcher's entire year before it ever really starts, and Hagenman's 2026 has been defined almost entirely by the recovery process rather than the rotation.

New York brought Hagenman aboard on a minor league deal prior to last season. He spent most of that year with Triple-A Syracuse, posting a 5.58 ERA while working as both a starter and a reliever. He made his MLB debut in April of this season and moved between the big-league club and the minors multiple times before the rib injury sent him to the 60-day IL — a designation that, as a general matter of league mechanics, removes a player from the 40-man roster count for the duration of the recovery.

His path back began midway through August with a rehab assignment at Syracuse. He made three starts as he built back up, reaching 64 pitches over four innings in his most recent outing last Friday. That workload is the clearest signal of what Wednesday night will look like: per the club announcement, Hagenman is expected to be somewhat limited in his start.

Is Hagenman stretched out enough to go deep into the game?

Almost certainly not, per the reporting. His last rehab outing topped out at 64 pitches over four innings, and the club's own announcement flags that he is expected to be limited. The Mets will almost certainly need their bullpen involved early — a familiar arrangement for a team navigating a September schedule with a rotation that has leaned on a small group of arms.

The numbers

Hagenman worked 23 2/3 innings over nine appearances with the Mets at the big-league level this season before his injury interrupted his spring. His Triple-A ERA last season was 5.58 across a split role as starter and reliever with Syracuse.

The Mets enter Wednesday at 64-78 (.451), sitting fifth in the NL East, 20 games back in the division. They rank 10th in the Wild Card picture, 10.5 games relative to the cut line, and arrive at Tropicana Field on a one-game losing streak.

Where the club stands

At 64-78, the Mets are not playing for October. The Wild Card math — 10th in the standings, 10.5 games from the cut line — makes the postseason a theoretical rather than practical conversation at this point in September. What the final weeks of the schedule offer instead is a look at pieces that could matter going forward, and Hagenman's return fits that frame.

After Wednesday's game in Tampa Bay, the Mets return to Citi Field for a weekend series against the San Francisco Giants. Nolan McLean is projected to start Friday against Matt Wilkinson, followed by Zac Thornton on Saturday against Anthony Molina.

McLean's presence on that schedule is worth noting in context: a week removed from the end of August, the rookie right-hander posted a 2.10 ERA in that month alone, maintaining a 3.06 ERA over 27 starts in 2026 and keeping his NL Rookie of the Year candidacy very much alive. The contrast between McLean's season and Hagenman's interrupted one captures something about where this roster sits right now — one arm building a case, another simply trying to get back on the mound.

The Dylan Ross piece

Ross was recalled from Triple-A Syracuse just days ago as part of September roster expansion — his MLB debut arriving on the first day of the month when rosters expand from 26 to 28 players. His return to Syracuse to make room for Hagenman is a straightforward transaction on paper, but it does compress what was a very brief window at the big-league level for the young right-hander.

Under general roster mechanics, September expansion allows clubs to carry up to 28 players on the active roster, which creates room for moves like Ross's initial call-up without requiring a corresponding subtraction. Hagenman's reinstatement from the 60-day IL, however, also involved filling the last spot on the 40-man roster — a separate accounting layer that required Ross to head back to Syracuse regardless of the expanded active roster allowance.

What we don't know yet

The club announcement does not specify a pitch limit or an inning target for Hagenman on Wednesday, only that he is expected to be somewhat limited. How the Mets structure the game behind him — and which relievers are available after recent use — is not addressed in the reporting.

It also remains to be seen how Hagenman fits into the rotation picture beyond Wednesday. Whether his role going forward is as a starter or a reliever is not addressed in the announcement. His rehab work this season came exclusively as a starter, but his time with Syracuse last year included both roles.

What to watch

The immediate question is how deep Hagenman goes Wednesday and how the Mets manage the back end of the game in Tampa Bay. Beyond that, the weekend rotation at Citi Field — McLean on Friday, Thornton on Saturday — will offer a clearer picture of how New York is distributing its remaining starts as the season winds toward its close.

For Hagenman specifically, Wednesday is less an audition than a reintroduction. More than four months between a spring injury and a September start is a long road back, and the 64-pitch ceiling he showed in Syracuse last Friday suggests the Mets are being measured about how quickly they push him. Whether he stays in the rotation, shifts to a relief role, or factors into the club's plans beyond this season are all questions the next few weeks will begin to answer — though none of them are answered yet.
