Overview
- Seattle confirmed the deal for cash considerations after New York designated Criswell for assignment earlier this week.
- Criswell was bumped from the Mets’ 40-man roster following their acquisition of Freddy Peralta and Tobias Myers from the Brewers.
- The Mariners designated left-hander Jhonathan Díaz for assignment to open a roster spot.
- Criswell is out of minor-league options and is pre-arbitration, with an $800,000 guaranteed 2026 salary originally set by Boston.
- The 29-year-old swingman logged a 3.57 ERA in 17 2/3 innings for Boston in 2025 and a 3.70 ERA over 65 2/3 innings at Triple-A, and he will compete for bullpen or spot-start opportunities in spring.
