Transactions

Nov. 24: The two teams have formally announced the swap.

Nov. 23: In an intriguing one-for-one swap of prominent veterans, the Mets and Rangers have agreed to a trade that will send second baseman Marcus Semien to Queens in exchange for outfielder Brandon Nimmo.  New York is also sending $5MM to help Texas offset some of the difference between the two players’ remaining salaries.

Reports emerged earlier this week that the Mets were open to moving Nimmo, though as of Thursday, trade talks reportedly hadn’t developed to the point that the Mets had approached Nimmo about waiving his contract’s no-trade clause.  Mike Puma of the New York Post wrote today that the team raised the subject of the Texas trade with Nimmo on Friday.  After a day’s consideration and a chat with Rangers ace (and his former Mets teammate) Jacob deGrom, Nimmo agreed to approve the deal.

Given the trade buzz this week, it isn’t entirely shocking to see the veteran outfielder’s time in New York come to an end.  That said, a straight-up swap for Semien is eye-opening, given how Semien is coming off a dismal year at the plate and comes with a significant future price tag in his own right.

Semien has $72MM and three seasons remaining on the seven-year, $175MM free agent deal he signed with Texas during the 2021-22 offseason.  Nimmo is owed $101.25MM through the 2030 season, as he has completed three years of the eight-year, $162MM free agent he signed to remain with the Mets in December 2022.  Since luxury tax figures are re-calculated to account for just remaining money owed in the wake of trades, Semien’s tax number is $24MM, and Nimmo has a $19.25MM figure (when factoring in the $5MM Texas is getting from New York).

The Mets are therefore taking on a slightly bigger tax hit while reducing the amount of overall dollars owed, while the Rangers are reducing their tax number but adding more overall money to their books.  That adds an interesting wrinkle for a Texas club that was expected to reduce payroll this winter, though it is worth noting that the Rangers cleared a good chunk of money off the books (a projected $21.1MM) on Friday with four non-tenders.

While the financial elements can’t be overlooked, the trade is also something of an old-school, need-for-need “baseball deal” that allows both the Mets and Rangers to address needs.  Beginning with Texas, the team was prioritizing a different offensive approach based around contact hitting and getting on base.

Nimmo’s strikeout rates have been overall middling throughout his career, though his chase and whiff rates have been consistently above average.  His walk rates had also been strong before suddenly dropping to 7.7% in 2025, in a career-low for the outfielder over a full season.  Still, Nimmo hit .262/.324/.436 with 25 homers over 652 plate appearances, translating to a 114 wRC+ over 652 plate appearances as New York’s everyday left fielder.  Public defensive metrics have also looked a lot more fondly on Nimmo’s glovework since he moved to left field from center field.

Since Adolis Garcia has now been non-tendered, Nimmo can slide into the left field position in Arlington, with Evan Carter or (probably more likely) Wyatt Langford moving into Garcia’s old spot in right field.  Second base is now opened up for Josh Smith or Ezequiel Duran in the short term, and top prospect Sebastian Walcott could also potentially find a home at the keystone depending on how long Corey Seager remains at shortstop.  The Rangers could also now explore the market for trade or free agent options at second base, with Semien no longer in the picture.

Selected 13th overall by the Mets in the 2011 draft, Nimmo has spent his entire career with the Amazins, becoming a fan favorite due to his consistent offense.  Injuries were a major hindrance for Nimmo earlier in his career and he is entering his age-32 season, but he has played in at least 151 games in each of his last four seasons.

In short, it seems like the Rangers feel more comfortable about paying Nimmo a bit of extra money over a longer term than they were paying Semien over his age 35-37 seasons.  A picture of durability throughout his career, Semien suffered a rare serious injury in 2025, as he was limited to 127 games by a Lisfranc sprain and a small fracture in his left foot.  Beyond just the health issue, Texas was perhaps more concerned about Semien’s dropoff at the plate over the last three seasons.

2023 was Semien’s last year as a premium hitter, as he hit .276/.348/.478 with 29 homers over 753 PA for the Rangers’ World Series team.  Semien delivered a 128 wRC+ that year, and his key role in Texas’ first championship will forever make him a beloved figure in Arlington.  After that dream season, however, Semien dropped to a 101 wRC+ in 2024, and then a subpar 89 wRC+ in 2025.  A .251 BABIP over the last two seasons is a partial explanation, yet the bigger culprit is a sizeable decline in power.

A change of scenery could perhaps get Semien’s bat going, even if Citi Field is known as a pitcher-friendly ballpark.  Semien does bring a right-handed hitting element to a Mets lineup that leaned left, and has now subtracted an everyday lefty swinger in Nimmo.  Beyond just Semien’s offense and his reputation as a clubhouse leader, he remains an outstanding defensive second baseman who just won his second career Gold Glove.

Mets president of baseball operations David Stearns stated that run prevention was a chief area of improvement for his team, so installing Semien at second base is a big defensive upgrade.  Removing a solid defender like Nimmo from left field is a hit unto itself, yet Jeff McNeil could make up some of the difference since left field now looks to be McNeil’s primary position with Semien locked into second base.  McNeil could also get part-time work in center field, or it is possible he might also end up on another roster, as rival teams have been discussing McNeil in trade talks.

It is a little surprising to see New York make such a prominent move to address second base, given how first and third base were the far more unsettled infield positions heading into the winter.  Pete Alonso’s free agency leaves first base open, and Brett Baty now looks to be staying at third base with Semien on board.  Top prospect Jett Williams is expected to make his MLB debut in 2026, and the outfield could now be Williams’ future position since Semien and Francisco Lindor have accounted for the middle infield.  Semien’s addition also brings fresh questions about how the Mets will incorporate Mark Vientos, Luisangel Acuna, and Ronny Mauricio into the infield mix, or if any of these players (or Baty) could now be trade chips.

Nimmo’s departure also means that the Mets could make a larger move to address their outfield.  The club was already expected to be looking for center field help, and Juan Soto could possibly be shifted over to left field if the Mets wanted to acquire a new right fielder.  This will probably spark some inevitable Kyle Tucker speculation, but Cody Bellinger is already known to be a player on the Amazins’ radar.

ESPN’s Jeff Passan was the first to report that the two teams were in the final stages of a deal involving Semien and Nimmo, and the New York Post’s Jon Heyman had the additional detail about the $5MM heading to Arlington.  The Athletic’s Will Sammon reported that Nimmo has agreed to waive his no-trade clause.
