What's Happening?
The Seattle Mariners have acquired right-handed pitcher Cooper Criswell from the New York Mets in exchange for cash considerations. Criswell, 29, had been designated for assignment by the Mets after being claimed off waivers from the Boston Red Sox in December. In the 2025 season, Criswell appeared in seven games for the Red Sox, achieving a 3.57 ERA. The Mariners have also designated left-hander Jhonathan Diaz for assignment to accommodate Criswell on their roster.
Why It's Important?
This trade is part of the Mariners' strategy to strengthen their pitching staff ahead of the new season. Criswell's addition provides the team with a potentially valuable bullpen asset, given his past performance and unique pitching style. For the Mets, the transaction allows them
to manage their roster and financial commitments more effectively. Such moves are common in the MLB offseason as teams prepare for spring training and the upcoming season.
