Mets Open to Moving All-Star Southpaw David Peterson
In a significant development at the MLB Winter Meetings, the New York Mets are reportedly open to trading All-Star starting pitcher David Peterson, according to sources cited by The Athletic. This potential move signals the Mets' aggressive approach to reshaping their roster as they look to fill critical gaps in the outfield, at first base, and within the bullpen.
Peterson, a 30-year-old left-hander, is generating considerable interest across the league, with the Mets reportedly holding a "high" asking price for his services. The club's willingness to entertain offers for a pitcher who earned his first career All-Star selection in 2025 underscores a strategic shift under President of Baseball Operations David Stearns, prioritizing a "need-for-need" type of trade to bolster other areas of the team.
A Tale of Two Seasons for Peterson in 2025
Peterson's 2025 campaign was a season of stark contrasts. He began the year in stellar fashion, emerging as arguably the Mets' most reliable starter and even tossing his first career shutout against the Washington Nationals on June 11. During the first half of the season, across 18 starts, Peterson posted an impressive 6-4 record with a 3.06 ERA and 93 strikeouts, culminating in his inaugural All-Star nod.
However, the second half saw a significant downturn in his performance. Peterson struggled considerably down the stretch, posting an 8.42 ERA over his final nine games, including a dismal 12.42 ERA across his last five outings. His September performances were particularly challenging, as he failed to pitch beyond six innings in any start, leading the Mets to ultimately bypass him for their final series of the regular season. Despite these late-season difficulties, Peterson finished 2025 with a 9-6 record, a 4.22 ERA, 150 strikeouts, and a 1.37 WHIP over new career-highs of 30 starts and 168.2 innings pitched. His overall 2025 ERA was a respectable 4.22 across a team-leading 168 2/3 innings, marked by a high 54.7% ground-ball rate.
Mets' Roster Needs Driving Trade Discussions
The Mets' openness to trading Peterson comes as the team faces several pressing roster concerns. The organization is actively seeking to address uncertainties at first base and designated hitter, particularly with Pete Alonso remaining unsigned. Additionally, the bullpen is a clear area of focus, especially after closer Edwin Díaz reportedly agreed to a deal with the Los Angeles Dodgers. While the Mets have signed Devin Williams to anchor the ninth inning, the team's setup relief, particularly among right-handers, is still seen as needing improvement.
Furthermore, the Mets are in the market for outfield help, a need that became more pronounced after a veteran-for-veteran swap involving Brandon Nimmo and Marcus Semien. President of Baseball Operations David Stearns has confirmed the club's interest in the outfield market, with Kyle Tucker or Cody Bellinger speculated as potential free-agent targets, though the team is also open to adding through trades.
Peterson, who is entering his final season of club control and is projected to earn $7.6 million in arbitration for 2026, presents an appealing trade chip for teams looking for a durable, All-Star caliber left-handed starter. His contractual situation offers a few million dollars of surplus value, and there's even a possibility he could pitch well enough to warrant a qualifying offer next winter.
Balancing Rotation Stability with Roster Flexibility
While Peterson's trade could address other team needs, it would also create another void in a Mets rotation that, despite its talent, lacks certainty. The team's starting pitching depth, though featuring a talented group, saw struggles from other key arms like Kodai Senga in the second half of 2025, who has also been mentioned in trade rumors. Moving Peterson could potentially open doors for younger starters within the Mets' system, such as Nolan McLean, Jonah Tong, Brandon Sproat, and Christian Scott.
Ultimately, the decision to potentially move David Peterson reflects the Mets' broader strategy to recalibrate their roster. Despite his All-Star status and moments of brilliance in 2025, the team appears determined to leverage his trade value to acquire pieces that address their most pressing deficiencies, aiming for a more balanced and competitive squad heading into the 2026 season.
