The Orioles missed out on Kyle Schwarber yesterday but are getting their big bat today, as ESPN’s Jeff Passan reports that they’re finalizing a five-year, $155MM deal with longtime Mets first baseman Pete Alonso. The agreement is in place with only a physical yet to be completed, Joel Sherman of the New York Post adds. There are no deferrals or opt-outs in the contract, per MassLive.com’s Chris Cotillo. Andy Kostka of the Baltimore Banner adds that Alonso receives a limited no-trade clause. Alonso is represented by the Boras Corporation.
It’s the second major defection from the Mets in as many days. Edwin Diaz spurned Queens for a three-year, $69MM deal with the Dodgers just yesterday. Alonso now heads to the Orioles, with whom he had an in-person meeting this week. While bolstering the rotation has been the obvious goal for Baltimore all offseason, the O’s have also been in pursuit of a major upgrade to the lineup. They offered Kyle Schwarber the same five-year, $150MM terms to which he agreed in his return to the Phillies and have now pushed incrementally further to give Alonso a record-setting average annual value for a first baseman over that same five-year term.
Alonso, who turned 31 over the weekend, famously rejected a reported seven-year, $158MM extension offer from the Mets back in 2023. He drew a fair bit of criticism for that decision, particularly when his market didn’t develop as hoped during last offseason’s initial foray into free agency. He wound up returning to the Mets on a two-year, $54MM deal that was frontloaded with a $30MM salary in 2025 and allowed him to opt back into free agency this winter. Between that $30MM, the $20.5MM he earned in his final season of arbitration eligibility and the newly promised $155MM from the Orioles, Alonso will end up with $205.5MM over the same seven years that would’ve been covered under the extension offer he turned down.
In Alonso, the Orioles are adding one of the steadiest power hitters on the planet. He’s slugged at least 34 home runs in every 162-game season since his 2019 debut, plus another 16 round-trippers in the shortened 2020 campaign. Dating back to 2019, Schwarber (268) and Aaron Judge (285) are the only players with more home runs than Alonso’s 264.
Steady as his power output has been, Alonso needed a “rebound” campaign of sorts in order to get this type of long-term deal. While his market last offseason was surely weighed down by a qualifying offer — players can only receive one QO in their career, so that wasn’t an issue this time around — Alonso had slugged a career-low 34 home runs with an increase in strikeouts and a downturn in his batted-ball metrics. His .240/.329/.459 output in 2024 was more good than elite.
The 2025 campaign brought improvements across the board. Alonso belted 38 homers and 41 doubles (up from 31 the year prior) while slashing .272/.347/.524 (141 wRC+). He lopped two percentage points off his strikeout rate, cutting it to a roughly average 22.8%, and saw enormous upticks in his average exit velocity (93.5 mph in ’25, 89.8 mph in ’24), barrel rate (18.9% vs. 13.2%) and hard-hit rate (54.4% vs. 46.4%). Alonso struggled through a poor month of July, but as the Mets were fighting for their postseason lives (and ultimately falling shy), Alonso put the team’s offense on his back alongside fellow stars Juan Soto and Francisco Lindor, raking at a .297/.339/.584 clip (153 wRC+) with 16 home runs and 15 doubles in 239 plate appearances from Aug. 1 onward.
Despite that Herculean finish to the season, Alonso received tepid interest from the only club he’s ever known. The Mets were reportedly reluctant to go beyond three years in their talks with Alonso, and the New York Post’s Joel Sherman reported in the aftermath of today’s agreement that the Mets never made a formal offer once it became clear where Alonso’s market was headed. That’s surely a point of frustration for the majority of Mets fans but also shouldn’t come as a major surprise; if the Mets were going to commit to Alonso long-term under president of baseball operations David Stearns and owner Steve Cohen, that likely would have happened last winter.
More to come.
