2021 was a fantastic year for the Seattle Mariners fam system. You’d be hard-pressed to find names that struggled to live up to their prospect pedigree. In fact, there were far more names establishing themselves as legitimate guys to watch, as opposed to burying themself in minor league purgatory.
The system really thrived in following its Control Dominate The Zone™ mantra. By and large, guys limited strikeouts and forced pitchers to throw them hittable pitches. The result is the optic of a mature system with patient hitters; arguably a building block to future success.
With the season behind us and the data in-hand, it’s a good time to reevaluate the guys at the top of this system and others to watch as they climb the ladder.
