The New York Mets have let Edwin Diaz walk to the Los Angeles Dodgers in a move that feels like they weren’t taking his free agency that seriously. It’s a significant blow, not just to the Mets’ roster, but to Mets fandom as a whole, given Diaz’s sizable impact on both. President of Baseball Operations David Stearns has a lot of work on his hands now. He has to make up for this, and making these three moves should be a must for him this offseason now.
Re-signing Pete Alonso
Letting Edwin Diaz, Brandon Nimmo, and Pete Alonso go in one offseason would put a massive damper on things for the Mets, and that’s putting it lightly. The Polar Bear has been one of baseball’s biggest power threats, and he continued to be just that in 2025. Overall, 2025 ended up being one of Alonso’s best seasons at the plate.
The first baseman turned in a .272/.347/.528 triple-slash, with 38 home runs over 709 plate appearances. Alonso’s isolated slugging percentage clocked in at .252, the fifth time in his career he has reached over .250. Alonso’s 8.7% walk rate may have been a career-low mark, but he struck out at a respectable 22.8% rate. Overall, he had a .368 wOBA and 141 wRC+, and his underlying numbers showed there is still more in the tank.
Alonso’s 93.5 MPH exit velocity and 18.5% barrel rate were both above the 95th percentile and dwarf his previous career-bests. Before 2025, his best exit velocity was 91 MPH in 2021, and his best barrel percentage was 15.8% from his 2019 rookie season. His .385 xwOBA and .560 xSLG% both trump his .380 xwOBA and .551 xSLG% from his 2019 rookie season. The only expected stat he wasn’t above the 95th percentile in was xBA (.278), and even then, it was still in the 88th percentile, another career-high mark.
While Alonso had a career year with the bat, he had a career-worst season with the glove. He had -9 defensive runs saved and outs above average. He ranked last among all 1B’s in the former stat, and second to last in the latter stat. But Alonso is reportedly willing to see more time at designated hitter. After losing Diaz and trading Nimmo, re-signing Alonso is a must for the Mets.
