Why the 2026 Mets Need to Move on from Their Longest Tenured Player
The Mets have a pivotal stretch of the 2026 season if they want to make the postseason, the front office faces an urgent decision in my opinion regarding the construction of their pitching staff. The Mets currently have only three starters and need to find two more starters to round out their starting rotation. The Mets have relied on bullpen games for the final two spots, and those bullpen games are starting to tax the bullpen. For years, the organization has exercised patience with left-hander David Peterson, hoping the former first-round pick would cement himself as a reliable, foundational arm. However, that patience has worn thin. The time has officially come for the Mets to cut ties and move on from Peterson, whose persistent inconsistencies continue to compromise the team's immediate success and stall its long-term future.
Peterson’s performance on the mound this season has left much to be desired, regardless of the role he is asked to fill. As a starting pitcher, his inability to pitch deep into games has routinely overtaxed the bullpen, characterized by high walk rates and a ballooning ERA that hovers above five. Sensing a need for change, team management attempted to pivot by shifting him into a bulk relief role. Unfortunately, the results out of the bullpen have been equally distressing. Peterson has looked uncomfortable in relief, failing to provide the stability required to bridge the gap to the late-inning high-leverage arms and frequently surrendering multi-run leads.
Beyond his immediate statistical struggles, keeping Peterson on the active roster creates a significant developmental bottleneck in the Minor Leagues. By continuing to hand valuable major-league innings to a struggling veteran with a limited ceiling, the Mets are actively blocking their premier young pitching talent from receiving earned opportunities in Queens. Most notably, rising prospect Jack Wenninger and rookie Jonah Tong, who had a few starts and bulk relief pitching outings this season. Both righties have done everything asked of them in the upper echelons of the Minor Leagues. Keeping Peterson in the fold delays the essential big-league exposure these young arms need to develop into focal points of the franchise's next great rotation.
Both right-handers have demonstrated that they are ready for the challenge. Tong continues to baffle hitters with an elite strikeout rate and a high-spin four-seam fastball, showcasing frontline starter potential despite pitching through typical developmental adjustments in Triple-A Syracuse. Meanwhile, Wenninger has been absolutely dominant this year, leaning on a devastating fastball-splitter combination to stifle opposing lineups and post an ERA near one. The Mets' front office must prioritize the future over the past; designating Peterson for assignment or moving him in a minor trade is no longer just a roster upgrade, but a programmatic necessity to clear a path for the next generation of arms at Citi Field.
