The Seattle Mariners' minor league system is gaining recognition as one of the best in Major League Baseball, particularly for its emphasis on developing pitchers. The current major league rotation features four homegrown talents: Logan Gilbert, George Kirby, Bryce Miller, and Bryan Woo, with Emerson Hancock also contributing after being drafted by the team. Gilbert and Kirby have both earned All-Star selections recently, underscoring the effectiveness of the Mariners' developmental approach.

Among the promising prospects is Logan Evans, who has emerged as Seattle's top pitching prospect. After a successful 2024 season with the Arkansas Travelers, where he posted a 3.20 ERA and struck out 98 batters, Evans is expected to make his major league debut soon. His insights on the evolving pitching strategies, particularly the resurgence of the two-seam fastball, highlight the Mariners' innovative approach to pitching development.
