The Mets currently have an off day on Thursday, but that doesn’t stop roster moves from continuing, and this season hasn’t unfolded as either the team or the fan base anticipated heading into 2026. Nevertheless, the MLB schedule presses on.
The Mets’ last series before the All-Star break is slated for this coming weekend against the Boston Red Sox. In the days leading up to that matchup, New York announced a release from within its organization. This comes on the heels of another quick roster move, illustrating how clubs constantly recalibrate their depth charts as the season progresses.
According to MLB.com’s transactions tracker, right-hander Alex Carrillo has been released by the Mets organization. The update notes, “New York Mets released RHP Alex Carrillo.” Carrillo’s departure comes just two days after he was designated for assignment by the team, marking his exit from the organization.
Carrillo, 29, spent this season with the Syracuse Mets, the Mets’ Triple-A affiliate. In 21 innings pitched at Syracuse, he carried an earned run average of 5.57. MLB Trade Rumors’ Steve Adams commented on Carrillo’s DFA, noting that while the 29-year-old had spent the majority of the season in the minors, he had previously spent time in the major leagues. The Mets originally signed him as an amateur free agent from independent baseball in November 2024. He made a brief major league debut last July, but allowed seven runs in 4 1/3 innings. Carrillo also posted an impressive 36.2% strikeout rate in Triple-A last year, yet his 14.7% walk rate remained a concern for evaluators.
Carrillo’s major league exposure has been limited. His only major league action to date came in 2025 with the Mets, where he appeared in four games across 4.2 innings, surrendering seven earned runs while punching out four. That brief stint stands as his sole experience at the highest level of the sport. Across 67 minor league innings at various stops, Carrillo has posted an ERA around 4.30 with 101 strikeouts, demonstrating a penchant for missing bats. Nevertheless, the Mets have not found a ongoing need for his services in recent seasons, leading to the latest organizational decision to part ways.
Moving forward, the Mets will look to regroup ahead of the upcoming interleague series with Boston. While the team navigates injuries, roster flexibility, and developmental opportunities, the front office will continue to balance the demand for competitive performance with the necessity of evaluating emerging talent from within the system. The decision to release Carrillo underscores the dynamic nature of MLB rosters, where players can be released, designated for assignment, claimed, or recalled as clubs fine-tune their depth charts in real time.
