A Kodai Senga Trade Is Worth Exploring for Pitching-Starved Padres

There was a point in 2025 where New York Mets starting pitcher Kodai Senga looked like he was ready for the breakthrough that would let him live among the game's top-tier arms. He pitched to a 1.39 ERA in the first half of the season and ended June with a 26.2 percent strikeout rate and 7.1 percent walk rate that each represented his best in an individual month up to that point. Then, the second half hit. 

As the Mets faltered in the standings, Senga played his part. His ERA skyrocketed to 6.56, his strikeout rate fell to 20.5 percent in July and August, and his walk rate sat at nearly 13 percent. He was touched for hard contact over 40 percent of the time (by FanGraphs' measure). While he's expressed a desire to stay in Queens, the Mets' attempt to rebuild their roster toward another postseason run has, naturally, led to Senga's name landing on the trade block this winter. Given their absence of starting pitching, it's also natural to ponder whether the San Diego Padres should make a run at the embattled starter. 

Despite the second-half swoon, Senga isn't without value. He has a career 3.00 ERA (3.82 FIP) in Major League Baseball, with a 26.8 percent strikeout rate and 11.1 percent walk rate across 285 innings. He's also averaged 5.5 innings per start, with longevity proving to be something of an issue for Padres starters in 2025. That's a lot of boxes checked by a player with two years remaining on his contract (and a club option for a third season). 

Those two years at a $28 million price point makes a whole lot of sense for the Padres, at least on paper. You're getting a pitcher with clear upside in a manner that would provide some stability in the starting five for the next two years, rather than relying on a veteran likely coming in on a one-year contract. To say nothing of the third-year club option that checks in at another $15 million. That's entirely affordable considering the upside. Again, though, we're talking about the addition on paper.

There's plenty of reason for pause when analyzing Senga as a potential trade target. While he's averaged decent innings when healthy, he also hasn't been particularly healthy in either of the last two years. He threw just five innings in 2024 before calf and shoulder injuries brought his season to its untimely end. A hamstring issue in June this season was likely a factor in some of his second-half issues that resulted in him spending the stretch run in Triple-A. And then you have to consider those struggles, too. Senga missed fewer bats and was much more liable to serve up barreled contact in July and August than in the months prior. For a team that struggled down the stretch like the Mets did last year, sending one of your highest-upside arms to the minor leagues speaks volumes about where they felt he was from a production standpoint. 

The upside is obviously tantalizing. Which is why, on paper, a pursuit of Senga on the part of the Padres makes a ton of sense. You get mid-to-front of the rotation production on at least a two-year contract. Numerous vacancies exist on that side of the staff. In an ideal world, you acquire Senga and stabilize your rotation in '26 and '27. 

But the upside is also likely a reason the Mets wouldn't give Senga away for a soft return, with the injury and performance woes in the last two seasons presenting an absurdly complex scenario. The Padres have so few resources for a trade in their organization at present. Can they afford to dispense with those resources in pursuit of a pitcher who offers so much variability in terms of outcomes? That would be difficult to reckon with when stability should be the name of the game. 

It borders on being a frustratingly mind-bending scenario for the San Diego Padres. Do you add a veteran starter looking to rebuild value on a reasonable contract or pursue the volatile arm that might cost you prospects but look healthy on the payroll (comparatively)? Not that we've heard anything on the part of interest the Padres could have. But considering where the rotation stands, any arm deemed available by way of the trade winds is going to be an obvious connection. Whether this particular arm could or should be a target, however, is a question with an answer that could roll on for miles.
