Kodai Senga May Be Changing The Mets Bullpen Plan For Good

Kodai Senga's impressive transition to the closer role offers a glimpse at potential solutions for the Mets' beleaguered bullpen as they eye the 2027 season.

Kodai Senga’s move to the ninth inning is starting to look like more than a temporary fix for the Mets.

With Devin Williams on the injured list after suffering a strained right shoulder, Senga has stepped into the closer’s chair and given New York exactly what it needed: calm, clean innings at the back of the bullpen. He has already converted all three of his save chances since taking over, working scoreless ninths in each outing. In those appearances, he has allowed only one walk in one game and a base hit in another.

The early numbers have been even better since the Mets made the move full-time. Over his last five scoreless innings out of the bullpen, Senga has allowed just three baserunners and struck out seven.

For a team that has been scrambling to piece together its relief group after David Stearns moved Luke Weaver, Brooks Raley, A.J. Minter, and Huascar Brazoban in deadline trades, that kind of stability matters.

The logic behind the switch is easy to see. The Mets believed Senga could be more effective in short bursts with a simpler pitch mix, and so far that idea has held up. He has looked comfortable, and the role seems to suit him.

Williams’ timeline is still unclear, but the Mets don’t have any reason to hurry him back. Given where they sit in the standings, there’s plenty of time to let Senga keep running with the job. He should get at least a few more weeks as the closer, and if the team keeps playing this well, more save chances should follow.

That creates a real decision point for the organization. Senga is under contract for another year at $15 million, and Stearns is going to want to squeeze value out of that deal. If Senga keeps handling the ninth inning like this, he could push past Williams for the role, especially with Williams coming off a shaky first season in Flushing.

There are still some boxes left to check. Senga needs to show he can handle back-to-back days, and there’s also the question of how he responds after a blown save. But right now, the Mets have found something that works, and that alone is a big development.

It could also have bigger implications down the line. If Senga proves he can close or at least handle late-inning duty in 2027, that would remove one more item from Stearns’ winter to-do list.

Williams has filled a setup role effectively before, including with the Milwaukee Brewers when Stearns was running baseball operations, so a future arrangement with Williams setting up for Senga is at least possible. That was also the Mets’ original idea when they signed Williams, before Edwin Diaz chose Los Angeles instead.

There’s still a long road ahead before Senga locks down the job for good. But with the Mets hot since the trade deadline and the bullpen in flux, he’s giving them something they didn’t necessarily expect to find: a legitimate answer in the ninth.

Mets Fans Can Finally Exhale Over One Infuriating Trade

The Darin Ruf deal has lingered in the background as one of those moves Mets fans could not help revisiting, especially after Ruf struggled so badly in Queens and J.D. Davis never found traction in San Francisco. Ruf hit just .152/.216/.197 with no home runs for the Mets, a line that quickly turned the trade into an easy target for second-guessing.

What makes the full picture easier to stomach now is how little the Giants have gotten from the other side of the return, either. Davis was released before the 2023 season, and the prospects sent over have offered only mixed results, with Thomas Szapucki slowed by injuries, Carson Seymour battling a 5.14 ERA over 49 innings and Nick Zwack struggling in the minors. For a trade that once felt like a clear loss, the long-term damage has been a lot less one-sided than it first appeared. [Read more 🡒]

Mets Just Sent A Harsh Message About Prospect Hype

The Mets barely had Gabriel Arias around long enough to let the roster move settle in before moving on. After two games, the club designated the former top 100 prospect for assignment to clear a spot for Christopher Morel, a reminder that pedigree alone does not buy much time in a crowded major league roster.

Arias arrived with the kind of name recognition that can invite patience, but his brief stint did not give the Mets much reason to hold the line. He struggled at the plate and in the field during limited major league action, and now has to pass through waivers as the organization continues sorting out both its prospect inventory and its depth chart.

Mets Next Manager Decision Could Be Bigger Than Fans Expected

The Mets are heading into another offseason search for a manager after parting ways with Carlos Mendoza, a move that only added to a stretch of underperformance and uncertainty around the club. As the front office looks for a reset, one familiar name has kept coming back into the conversation: Carlos Beltran, whose place in Mets history and ties to the organization make him one of the more intriguing possibilities on the board.

Beltran is not a cleanly simple fit, though, given how his last turn in the dugout ended after he resigned in 2020 amid the Astros cheating scandal. Even so, the idea of a return has lingered because of his connection to the franchise and the possibility that the Mets could be willing to revisit a bold, familiar option as they try to steady things for the next chapter.
