When the 2025 season ended, there was a narrative espoused by the Mets’ front office that one of the goals of the offseason was to focus on run prevention. This narrative more or less went out the window with the signing of Jorge Polanco and Bo Bichette, but the concept endures in the trade of Brandon Nimmo to the Rangers in exchange for Marcus Semien.
The deal was a palatable one for both sides because it was a swap of contracts that have not aged well, and for players who filled organizational needs
for their new teams. Semien, the reigning American League Gold Glove winner at second base, is entering his fifth year of a seven year, $175 million deal. His deal has two fewer years remaining on it than Nimmo’s does. His story is a well-known one: a former shortstop who excelled defensively when he switched to second and who, after a few boffo offensive seasons, has cooled off with the bat considerably.
All of that somewhat belies what a useful player Semien still is. Over his past two seasons, he ‘s been worth 7.4 bWAR with an OPS+ of 103 and 97, respectively. Obviously, much of his value came from his defensive skills, but he was still the 13th most valuable second baseman in baseball last year. And while, yes, Semien is entering his age 36 season, he’s just three years removed from a season when he came in third place in the AL MVP voting and when he slugged 29 home run and 100 RBIs. It wasn’t his best season (that would be 2019’s 8.4 bWAR season), but it was a very valuable one.
But let’s pretend that 2025 is more where he is offensively for the last three years of his contract with the Mets. If he can provide quality defense up the middle and hit 15ish home runs while playing just about every day, the Mets’ offense should be able to more than carry him at the bottom of the lineup. That’s still a trade the Mets likely make, even if Semien isn’t quite who he used to be.
But the change of scenery, protection in the lineup, and his underlying skills could come together in another 2022 season for Semien. And if it does, the Mets’ lineup will be truly formidable.
