Kodai Senga struggles with command in second Triple-A rehab start

What happened

Kodai Senga's second Triple-A rehab outing of 2026 did not go as the Mets would have hoped. Per MLB.com, the right-hander struggled with command throughout the start — a development the outlet characterizes as a signal that he is not yet ready to rejoin New York's rotation.

The rehab process, by its nature, is rarely a straight line. A second start that raises command concerns rather than resolving them is the kind of update that extends timelines rather than shortens them, and MLB.com's framing stops well short of attaching any return date to Senga's name.

Why it matters

Command is a specific and meaningful category of concern. It is distinct from velocity, from raw stuff, from the structural health markers that typically dominate injury-return coverage. A pitcher can be physically sound and still be working to find the strike zone with consistency. Whether Senga's command issues are mechanical, a matter of game-shape timing, or something else entirely is not addressed in the report, and the desk does not speculate on what it was not told.

What MLB.com does make clear is that two rehab starts in, the answers are not yet in. The outlet's characterization — that the outing signals he is not yet ready — is its own framing, not a direct club statement. Whether the Mets have offered any formal internal assessment of the start is not specified.

Under general league rules, pitchers on a rehab assignment have up to 30 days before a club must either activate them or make a roster decision. Where Senga stands within that window is not detailed in the report, but the existence of a second start marked by command struggles means the clock is running and the picture remains unclear. The 30-day ceiling is not a soft suggestion; at some point, the organization will be required to act, and the shape of that action will depend heavily on what the next outing — if one is scheduled — looks like.

Where the club stands

The Mets enter this weekend at 74-88 (.457), sitting fifth in the NL East, 20 games back in the division. Their Wild Card position ranks 10th, 14.0 games relative to the cut line. They have been eliminated from both the division race and the Wild Card race, and they carry a one-game losing streak into a three-game home series against the Miami Marlins at Citi Field.

Friday's probable matchup has Freddy Peralta opposing Max Meyer. Saturday sends Christian Scott to the mound against Tyler Phillips. Sunday features Nolan McLean against John King.

None of those names is Senga, which is consistent with MLB.com's reporting that he is not yet ready to return. The rotation as currently constructed for this series moves forward without him.

The numbers

The Mets' 74-88 record and fifth-place standing in the NL East frame the operational backdrop here. A 20-game deficit in the division and a Wild Card rank of 10th — 14.0 games relative to the cut line — mean the standings have already rendered their verdict on this season. The numbers are not a knock on any individual; they are simply the context in which Senga's rehab timeline now sits.

What we don't know yet

The report does not specify how many innings Senga threw, how many walks he issued, what his velocity looked like, or what the club's internal read on the outing was. There is no timetable attached to his return, no indication of whether a third rehab start is being planned, and no detail about where he falls within his 30-day rehab window.

MLB.com's framing — that he is not yet ready to return — is the outlet's characterization. A direct club statement on the start's implications is not part of the report.

What to watch

### When could Senga return?

The report does not say. What it establishes is that his second rehab start surfaced command concerns rather than clearing them, and that he is not yet ready to return per MLB.com's account. A third rehab start, if one is scheduled, would be the next meaningful checkpoint — and whether the command issues that appeared in this outing begin to resolve or persist will shape whatever comes after.

The 30-day rehab window under general league rules is finite. At some point, the Mets will need to activate Senga, transfer him to a different injured list designation, or make another roster decision. The report gives no indication of where that deadline falls, which means the next update from the club or from MLB.com will carry real weight.

The broader context is worth sitting with for a moment. In a pennant race, a command-troubled rehab start from a front-line starter would carry urgent operational weight — every rotation slot matters, every healthy arm is a resource. In a season that has already resolved itself in the standings, the calculus is different. The question of when Senga returns becomes less about October and more about what the organization learns between now and the end of the regular season.

That is not a trivial question. A pitcher working back from injury, logging rehab starts, finding or not finding his command — that is information the Mets carry into the offseason. The second rehab start is a data point, even if it is not a reassuring one.

For a Mets fan watching this weekend's series against Miami, the Senga situation is the subplot running alongside the box scores. The rotation names on the mound — Peralta, Scott, McLean — are the present. Senga, working through command issues at Triple-A, is the question the organization is still trying to answer. How quickly that answer arrives, and what form it takes, is the thread worth following as the calendar moves toward the end of the regular season.
