Mets Claim Cooper Criswell Off Waivers From Red Sox

Boston's plan to keep the swingman by guaranteeing him $800,000 for 2026 did not prevent a claim.

Overview

  • The waiver claim came less than a day after Boston designated the 29-year-old right-hander to open a 40-man spot following a five-player trade with the Pirates that brought in Johan Oviedo and prospects.
  • Boston had signed Criswell to a fully guaranteed $800,000 deal for 2026, slightly above the league minimum, in an effort to discourage other clubs from claiming him.
  • Criswell offers starting and relief experience and posted a 3.57 ERA over 17.2 major league innings in 2025 after logging a 4.08 ERA across 99.1 innings for the Red Sox in 2024.
  • He spent much of 2025 with Triple-A Worcester, recording a 3.70 ERA over 65.2 innings before a late-season stint on the minor league injured list for right elbow inflammation.
  • The Mets view him as low-cost depth for long-relief or swingman work, and he arrives with familiarity with pitching coach Justin Willard from their time in Boston.
