Kodai Senga’s Minor League Demotion: The New York Mets’ Gut-Wrenching Decision

The New York Mets just pulled off one of the most stunning moves of the 2025 season, and honestly, it feels like watching your favorite player get traded to your rival team. Kodai Senga, the guy who was supposed to be the Mets’ ace heading into Spring Training, is now packing his bags for Triple-A Syracuse after the team optioned him on Friday.

Let that sink in for a moment. A pitcher earning $75 million over five years—a guy who finished second in NL Rookie of the Year voting just two seasons ago—is heading to the minors. This isn’t your typical September roster shuffle; this is a seismic shift that has Mets fans scratching their heads and wondering what went wrong.

The Numbers Tell a Brutal Story

Senga’s recent struggles aren’t just disappointing—they’re downright painful to watch. Since returning from a hamstring injury on July 11, the Japanese right-hander has posted a ghastly 5.90 ERA across nine starts. His last eight outings have been even worse, with a 6.56 ERA that would make even a Little League coach cringe.

Remember when Senga was virtually unhittable in the first half? The guy went 7-3 with a microscopic 1.47 ERA through his first 13 starts, looking every bit like the dominant pitcher the Mets thought they were getting. But that hamstring strain against the Nationals on June 12 seems to have broken something fundamental in his mechanics.

The most telling stat? Senga has allowed at least one home run in all but two of his nine starts since returning from injury. Compare that to the four total home runs he gave up in his first 73.2 innings of the season, and you’ve got yourself a mystery that would stump Sherlock Holmes.

The Human Side of a Business Decision

Here’s where things get interesting—and honestly, a bit heartwarming in this cold world of professional sports. According to SNY’s Andy Martino, the relationship between Senga and the Mets organization remains rock solid. The team didn’t just blindside their struggling pitcher with a demotion notice.

Instead, they included Senga in the decision-making process, treating him with the respect that a veteran of his caliber deserves. The 32-year-old had to consent to the move, thanks to a clause in his contract, and he did so “without issue,” feeling respected throughout the process. This isn’t a punishment—it’s a reset button. The Mets are hoping that two starts in Syracuse will help Senga rediscover the magic that made him nearly untouchable earlier this season.

The Rookie Revolution In Queens

While Senga heads to Syracuse to figure things out, the Mets are doubling down on youth in a way that would make even the most optimistic fan nervous. The team now has three rookies in their six-man rotation: Brandon Sproat (who’s making his MLB debut Sunday), Nolan McLean, and Jonah Tong.

Think about that for a second. A team fighting for a playoff spot is trusting rookies with consecutive starts in crucial September games. It’s either brilliant or completely insane—probably both. McLean has been absolutely electric since his call-up, posting a 1.37 ERA in four starts that have Mets fans wondering if they’ve found their next ace. Tong looked solid in his debut, allowing just one earned run in five innings. Now all eyes are on Sproat to complete the rookie trifecta.

The Playoff Picture Gets Messier

The timing of this move couldn’t be more crucial. The Mets sit at 75-65, holding onto the third wild card spot, but with the Cincinnati Reds breathing down their necks, just five games back. Every decision from here on out feels like it carries the weight of the entire season.

Senga’s demotion doesn’t affect his postseason eligibility—he was on the roster before the August 31 deadline. But whether he’s worth carrying on an October roster is now a legitimate question. The guy who was supposed to anchor the Mets’ playoff rotation might not even make the postseason squad. The Mets’ rotation depth chart now reads like a medical report, with injuries to Frankie Montas, Griffin Canning, and Tylor Megill forcing the team to rely on unproven arms at the worst possible time.

What This Means For the Stretch Run

Let’s be real—this move screams desperation wrapped in optimism. The Mets are essentially saying they would rather trust inexperienced rookies than continue rolling Senga out there every fifth day, watching him get shelled by opposing hitters who have clearly figured him out.

But here’s the thing: sometimes desperate moves work. Sometimes that rookie pitcher channels his inner magic and carries a team to October glory. Sometimes the veteran finds his mojo in the minors and returns as the pitcher everyone thought he was.

The Mets’ offense has been scorching hot lately, posting a .908 OPS since August 6—the best in baseball. They’re scoring runs in bunches, which means their pitchers don’t need to be perfect. They just need to be competent enough to keep games within reach.

The Road Back To Relevance

Senga can be recalled as early as September 20 (unless he’s replacing an injured player), which gives him just enough time for those two anticipated Triple-A starts. The question isn’t whether he’ll be back—it’s whether he’ll be the same pitcher who dominated hitters earlier this season.

This story feels far from over. Senga’s talent didn’t just evaporate because of a hamstring injury, even though his recent performances suggest otherwise. Sometimes a change of scenery, even if it’s just a step down to Triple-A, can work wonders for a struggling pitcher’s confidence.

The Mets are betting their playoff hopes on rookies who have barely tasted major league pitching, while their former ace tries to rediscover his form in Syracuse. It’s the kind of September drama that makes baseball simultaneously beautiful and brutal. Only time will tell if this gamble pays off—but one thing’s for sure: the Mets aren’t going down without a fight.
