The 2025 MLB offseason is shaping up to be one of the most dramatic in recent memory, with major stars opting out of contracts and franchises preparing for sweeping roster adjustments.
At the center of this activity is the Boston Red Sox, who are now expected to pursue New York Mets slugger Pete Alonso as a potential replacement for departing third baseman Alex Bregman. This scenario has triggered widespread debate, touching on payroll strategy, positional needs, and the ever-shifting dynamics of free agency.Both Alonso and Bregman enter the market with strong statistical resumes and significant contract expectations.
Their decisions not only influence their respective teams but also ripple across the league as clubs map out long-term roster building. With Boston searching for an elite power bat and the Mets looking to reshape their financial structure, this rumored alignment carries major implications.
How This Trade Scenario Takes Shape
Alex Bregman officially opted out of his Red Sox deal, turning down $80 million in pursuit of a projected five- or six-year contract worth around $150 million.
Despite an injury-shortened 2025 season, he produced a steady .273/.360/.462 slash line, 18 home runs, and 3.5 WAR - strong enough to make him one of the most attractive infield options on the market.With third base now open, Boston has shifted attention toward Pete Alonso, who also opted out following a powerful 2025 season. Alonso recorded 38 home runs, 126 RBIs, and a .256/.350/.480 line with 5.0 WAR. His expected price tag is even steeper, with projections exceeding $170 million over six years.
Alonso would primarily handle first base or a DH role, allowing the Red Sox to elevate infield prospects like Marcelo Mayer to cover third base defensively.
