What's Happening?
The Seattle Mariners have acquired right-handed pitcher Cooper Criswell from the New York Mets in exchange for cash considerations. Criswell, who was recently designated for assignment by the Mets, had
been claimed off waivers from the Boston Red Sox in December. The 29-year-old pitcher appeared in seven games for the Red Sox in the 2025 season, posting a 3.57 ERA over 17.2 innings. Throughout his MLB career, Criswell has pitched 154.2 innings with an ERA of 4.48, having also played for the Angels and Rays. The Mariners have designated left-hander Jhonathan Diaz for assignment to make room for Criswell on their roster.
Why It's Important?
This acquisition is significant for the Mariners as they bolster their bullpen with a pitcher who has shown potential in the major leagues. Criswell's side-winding pitching style adds a unique element to the Mariners' pitching staff, which could be advantageous in matchups against certain batters. For the Mets, this move clears roster space and provides financial flexibility. The transaction reflects the ongoing strategic adjustments teams make during the offseason to optimize their rosters ahead of spring training.
What's Next?
Criswell will likely join the Mariners for spring training, where he will have the opportunity to secure a spot in the bullpen. The Mariners will assess his performance and fit within their pitching rotation. Meanwhile, the Mets will continue to evaluate their roster needs and may pursue additional trades or signings to strengthen their team before the season begins.
