The Mariners' acquisition of Cooper Criswell addresses a need for additional pitching depth behind their strong starting rotation. While Criswell's career numbers don't jump off the page, he has shown flashes of effectiveness as a spot starter and long reliever. His most extensive big league look came in 2024 with the Red Sox, where he tossed 99 1/3 innings with a 4.08 ERA.

He also has familiarity with new Mariners outfielder Rob Refsnyder, as they were teammates in Boston.
