The New York Mets have officially entered a period of major transition after parting ways with manager Carlos Mendoza following a disappointing 34-47 start to the 2026 season. With playoff hopes fading and the trade deadline approaching, the organization appears ready to reshape its roster, and Mendoza’s dismissal could be only the beginning of a much larger overhaul.
The first significant move came even before the managerial change was announced, as the Mets traded veteran starting pitcher David Peterson to the Chicago Cubs. Peterson, who had been the club’s longest-tenured player, became the first notable casualty of New York’s disappointing campaign, signaling that the front office is prepared to make difficult decisions.
Interim manager Andy Green now takes over in the dugout, bringing a fresh perspective after previously serving in the front office. His arrival could lead to changes in both playing time and roster construction over the coming weeks as the Mets evaluate which players fit into their long-term plans.
With roughly a month remaining before the MLB trade deadline, several veterans and fringe contributors could soon find themselves wearing different uniforms. Here are three players who appear to be among the most likely trade candidates.
1. Brooks Raley Could Become One of the Deadline’s Most Valuable Bullpen Arms
Veteran left-handed reliever Brooks Raley may ultimately be the Mets’ most attractive trade asset.
The 38-year-old has quietly enjoyed another outstanding season, entering Sunday’s action with a stellar 2.40 ERA while continuing to serve as one of the club’s most dependable late-inning relievers. His consistency has remained impressive despite returning from Tommy John surgery, proving he can still handle high-leverage situations.
Raley has formed an effective bullpen tandem with fellow left-hander A.J. Minter, but with Minter still working his way back from injury, Raley could become one of the most sought-after relief pitchers available before the deadline.
Contending teams are always searching for experienced bullpen help, particularly reliable left-handed relievers capable of neutralizing dangerous hitters in October. Given his postseason experience, veteran leadership, and consistent production, Raley could command a respectable prospect package if the Mets decide to move him.
Although he has been an important contributor throughout his five seasons in New York, his timeline no longer aligns with a franchise likely entering another phase of rebuilding.
2. Eric Wagaman Could Be Moved to Make Room for Younger Talent
First baseman and outfielder Eric Wagaman has made the most of his limited opportunities since joining the Mets.
Used primarily against left-handed pitching, the veteran has provided solid production, batting .294 against southpaws while hitting two home runs. His career numbers also suggest he can continue serving as an effective platoon hitter.
Despite that success, Wagaman’s future with the organization appears uncertain.
The Mets have several younger players they want to evaluate, including promising prospect Nick Morabito, who could receive regular playing time if a roster spot becomes available. Since Wagaman is unlikely to be part of the club’s long-term plans, New York could decide to move him before the deadline in exchange for a modest return.
While his market value may not be particularly high, contenders looking for a right-handed bench bat capable of handling left-handed pitching could view him as an inexpensive addition.
3. Mark Vientos’ Future in Queens Growing Increasingly Uncertain

Perhaps the most intriguing trade candidate is Mark Vientos.
Once viewed as a key part of the Mets’ future, Vientos has struggled to establish himself this season. He has managed just 10 home runs while posting an OPS below .650, falling well short of expectations.
His path to regular playing time has become even more complicated following comments from interim manager Andy Green, who indicated that Jared Young will receive the majority of the starts at first base moving forward.
That decision effectively pushes Vientos into a designated hitter role, but even those opportunities may soon disappear.
Veteran Jorge Polanco has begun a rehabilitation assignment at Triple-A Syracuse and is expected to serve primarily as the designated hitter once he returns from injury. With Young expected to handle first base and Polanco projected to occupy the DH spot, Vientos could find himself without a clear role on the major league roster.
If another organization still believes in his offensive upside and former prospect pedigree, the Mets could explore moving him before the deadline rather than allowing his value to decline further.
More Changes Could Be Coming
The firing of Carlos Mendoza may represent only the first major step in what could become a busy summer for the Mets.
As the front office shifts its attention toward the future, veteran players and those without long-term roles are expected to draw increasing interest from contenders seeking reinforcements. With Andy Green now overseeing the clubhouse and the trade deadline rapidly approaching, Brooks Raley, Eric Wagaman, and Mark Vientos all appear to be among the players most likely to headline New York’s next wave of roster changes.
