Analysis: Where Mariners’ Farm System Ranks and What Comes Next

As the Mariners attempt to claw their way back into playoff contention, it can be easy to focus on the letdowns of the major league club. The organization has plenty of other reasons to be optimistic, with a talent-rich farm system that would be the envy of most teams.

When Seattle traded Luis Castillo to the Chicago White Sox, it was initially billed as a salary dump and a way to reduce the logjam of starters in the rotation. The Mariners acquired Seranthony Domínguez, who slots in as a middle-relief option. Seattle also received prospect Boston Smith, who has been mashing with six home runs in his first 11 games. The catcher adds to an already impressive minor league system.
