Mets' Updated Lineup After Pete Alonso Reportedly Leaves for $155M Orioles Contract

The New York Mets are continuing to reshape their roster after a disappointing playoff miss in 2025.

ESPN's Jeff Passan reported Wednesday that longtime Mets first baseman Pete Alonso left in free agency to join the Baltimore Orioles on a five-year, $155 million deal.

The Mets already parted ways with outfielder Brandon Nimmo earlier this offseason as part of a trade involving former Texas Rangers second baseman Marcus Semien.

Here's a look at the Mets' updated lineup now that Alonso and Nimmo are leaving Queens.

The Orioles, meanwhile, will bring in Alonso to a team already staffed with young talent like Gunnar Henderson, Adley Rutschman and Jackson Holliday.

After missing out on Alonso, the Mets could potentially try to add more power to this lineup by targeting a slugger like Cody Bellinger in free agency.

The Mets already missed out on reported free agency target Kyle Schwarber, who recently re-signed with the Philadelphia Phillies on a five-year, $150 million deal.

Alonso slashed .272/.347/.524 with 38 home runs in his fourth straight All-Star season for the Mets while batting in a team-leading 126 runs and an NL-high 41 doubles.

Nimmo, who slashed .262/.324/.436, ranked third on the team with 92 RBI and fourth with 25 home runs.

Those two players combined for almost a quarter of all the hits the Mets recorded on their way to missing the 2025 postseason.

Adding Bellinger (.272/.334/.480 with 29 home runs and 98 RBI for the New York Yankees last season) would help the Mets get some power back into their lineup.

Other big hitters still available on the free agency market include Kyle Tucker and Alex Bregman, both of whom remained unsigned as of Alonso's departure.

It remains to be seen, however, if the Mets are handing out the kind of term they might need to offer in order to win those bids.

The Mets seemingly favored Semien's shorter-term contract in the Nimmo deal, and The Athletic's Will Sammon reported the club was "not comfortable" matching the term or money from Alonso's deal with the Orioles.

The club may need to consider making some concessions on term in order to add some batting power into the lineup ahead of 2026.

The turnover in Queens is going beyond the batting order. The Mets also recently lost veteran closer Edwin Díaz to the Los Angeles Dodgers shortly after bringing in reliever Devin Williams.
