Kodai Senga completes another relief outing in return from injury
The Mets right-hander is working through a relief checklist as he builds back from injury, though his ninth inning Sunday did not go as planned, per Anthony DiComo.

Kodai Senga checked off another box in his relief-pitcher progression Sunday, though the ninth inning itself did not cooperate, per Anthony DiComo. The Mets right-hander is working through a structured checklist as he builds back from injury, completing a milestone he had not previously reached in his return.
The nature of the checklist, the specific milestone, and the details of Sunday's ninth inning were not disclosed in the report. What is clear: Senga is advancing through a relief role as the Mets manage his workload, a path that typically involves escalating leverage, inning assignments, and pitch counts as a pitcher regains form.
What happened
Senga threw in the ninth inning Sunday, per DiComo, and the outing did not go his way. Despite the result, the appearance represented progress in his return from injury: he completed something he had not done before in this progression. The report did not specify the opponent, the game situation, or the statistical outcome of the inning.
The Mets have been deploying Senga in relief as he works back, a common framework for pitchers returning from extended absences. The checklist approach allows the club to control his exposure while evaluating his readiness for a larger role, whether that remains in the bullpen or eventually returns him to the rotation.
Why it matters
Senga's return carries operational weight for a Mets club that has been eliminated from the division race and sits 10.5 games behind the Wild Card cut line. The 65-78 record and fifth-place standing in the NL East have shifted the focus of the final weeks to evaluation and preparation for next season, and Senga's health is central to that calculus.
His recent history with injury has made the Mets cautious in his return, using relief outings to build his arm strength and confidence without the full workload of a starting assignment. The checklist structure suggests the club is methodical in its approach, likely tracking metrics such as pitch count, velocity, recovery time, and performance in different game situations. Each box checked is a step toward determining whether Senga can contribute meaningfully in September or whether the focus shifts entirely to his readiness for spring training.
Where the club stands
The Mets are 65-78, 20 games behind in the NL East and 10.5 games out of the Wild Card picture. They have been eliminated from the division race and are riding a one-game winning streak heading into a three-game series against the Milwaukee Brewers at Citi Field.
The rotation for that series features Zac Thornton on Tuesday, Robert Stock on Wednesday, and Sean Manaea on Thursday. The absence of Senga from the probable-pitcher list underscores his continued relief role, at least for now. Whether he remains in that role through the end of the month or transitions back to starting will depend on how the checklist unfolds and how the club weighs the risk of extending him against the value of additional data.
The Brewers series offers a chance to evaluate the pitching staff in a low-stakes environment, with the postseason out of reach and the focus on individual development rather than standings. Senga's progression is part of that broader picture, as the Mets assess which arms could anchor the rotation and which will fill out the bullpen depth chart.
What we don't know yet
The report did not specify what milestone Senga completed, what went wrong in the ninth inning Sunday, or how many pitches he threw. The nature of the checklist itself remains undisclosed: whether it involves specific pitch counts, consecutive outings, back-to-back days, or performance thresholds is not clear.
It is also unknown whether Senga will continue in relief through the end of the season or whether the Mets plan to stretch him out into a starting role in September. The club has not announced a timeline for his return to the rotation, and the report did not indicate whether such a move is under consideration.
The opponent and game situation for Sunday's outing were not provided, nor was any statistical line. Without those details, it is difficult to assess the severity of the setback or whether it will alter the Mets' plan for his next appearance.
What to watch
Senga's next outing will clarify whether Sunday's rough ninth inning was a minor hiccup or a sign that the checklist needs to slow down. The Mets have three games against the Brewers this week, and if Senga is available in relief, his usage pattern will offer clues about where he stands in the progression.
If the club continues to deploy him in low-leverage situations, it suggests they are still building his arm strength and are not yet confident in his ability to handle high-pressure innings. If he appears in closer games or in back-to-back outings, it would signal that the checklist is advancing and that the Mets are testing his readiness for more demanding assignments.
The broader question is whether Senga could make a start before the season ends. The Mets have games remaining, and the final weeks of a lost season are often used to stretch out pitchers who have been limited by injury. If Senga is to make that transition, it would likely happen in early September, giving him multiple turns to build up his pitch count and prepare for an offseason program.
For now, the checklist continues, one box at a time, with the Mets balancing the need for information against the risk of setback. Sunday's ninth inning did not go as planned, but the milestone was reached, and the progression moves forward.
