Cooper Criswell Stats & Bio | Mariners Pitcher

About Cooper Criswell

Cooper Criswell stands tall on the mound for the Seattle Mariners, bringing an imposing 6'6" frame and sharp competitive instincts to every outing as pitcher number 18. Born on July 24, 1996, in Carrollton, Georgia, Criswell developed his craft through the collegiate ranks at the University of North Carolina, where he honed the mechanics and mental approach that define his game today. The right-hander has been nothing short of dominant in recent action, posting a pristine 0.0 ERA while striking out nine batters across 8.1 innings in just three appearances. His ability to generate strikeouts while keeping hitters off the scoreboard speaks volumes about both his stuff and his poise. At just 200 pounds on that tall frame, Criswell proves that deception and precision can be just as powerful as pure velocity.
