Mets' Most Glaring Question at First Base Before Opening Day For the first time since 2018, Pete Alonso will not be the New York Mets starting first baseman on Opening Day. After declining to re-sign Alonso, who instead signed a five-year deal with the Baltimore Orioles, the Mets opted to pursue a different approach at first base. This decision was largely influenced by Alonso’s lack of defensive prowess at the position. With Opening Day just two days away and a new player occupying the first base spot, questions remain about whether the Mets made the right move by not bringing back Alonso. The Mets’ choice to move away from Alonso has sparked debate, particularly given his absence from the team. While Polanco has performed reasonably well in his nine Grapefruit League games at first base, his first error of the spring training season against the Houston Astros raised concerns. Polanco sought guidance from former Mets first baseman and captain Keith Hernandez on adjusting to the position, a step that could prove valuable in the long term. However, the error highlighted the challenges of transitioning to a new role. Beyond Polanco, the Mets have limited internal options to fill the first base position. When Polanco takes a break, Brett Baty and Mark Vientos are the primary alternatives. Baty, who had a standout 2025 season with the Mets, lacks significant experience at first base. Meanwhile, Vientos, despite his prior experience at the position, faces uncertainty due to his underwhelming 2025 performance and a lackluster spring training showing. Both players bring potential but also risk, leaving the Mets to balance between familiarity and fresh talent. This gamble represents a significant risk for the team.#new_york_mets #baltimore_orioles #pete_alonso #keith_hernandez #sandy_alderman
