The Boston Red Sox are actively seeking to bolster their starting rotation this offseason, having recently acquired Garrett Crochet from the Chicago White Sox. They have shown interest in young pitchers from the Seattle Mariners, including Bryan Woo and Bryce Miller, but have faced rejection in their attempts.

Current discussions suggest the Red Sox may pursue Luis Castillo, though negotiations are complicated by differing expectations. The Mariners might prefer to receive a starting pitcher rather than just offensive talent in return, despite their need for runs.

Red Sox reporter Alex Speier speculates that Kutter Crawford could be part of a trade package, potentially along with offensive assets like Triston Casas and Wilyer Abreu, who recently earned a Gold Glove. The situation remains fluid as both teams navigate their needs.

As the winter meetings approach, former MLB general manager Jim Bowden suggests the Seattle Mariners trade pitcher Bryce Miller to the Baltimore Orioles for top prospect Coby Mayo. While this idea is speculative, Bowden believes it could benefit both teams.

Miller, who had a strong season with a 2.94 ERA, is part of a talented Mariners rotation. Mayo, ranked as the No. 8 prospect, could fill a need for Seattle in the infield.

The Seattle Mariners are experiencing a significant loss in their organization as minor league pitching coordinator Matt Pierpont departs for a prominent position with the St. Louis Cardinals. This marks the second consecutive year the Mariners have lost a key pitching coordinator, raising concerns about a 'brain drain' as other teams seek to capitalize on the Mariners' successful player development.

Pierpont expressed gratitude for his time with the Mariners, highlighting the honor of working with talented individuals. The Mariners have successfully developed pitchers like Logan Gilbert, George Kirby, Bryce Miller, and Bryan Woo, contributing to one of the strongest starting rotations in Major League Baseball.

The Seattle Mariners are gearing up for a pivotal 2025 season after missing the playoffs for the 22nd time in 23 years. With a revamped coaching staff, questions remain about the roster, particularly the starting rotation, which is expected to remain elite.

Logan Gilbert, coming off an impressive 2024 season with an All-Star selection and strong performance metrics, is projected to lead the rotation again. Despite potential regression for the overall pitching staff, Gilbert's consistency is expected to help maintain their competitive edge.

The Seattle Mariners have emerged as a model for building a successful starting rotation, boasting a group that had remarkable performances last season. Four of their five starters were developed through their own system, contributing to a rotation with impressive statistics, including all five maintaining a sub-3.50 ERA.

However, the latest projections from FanGraphs suggest potential challenges ahead. Despite being ranked as having the second-best rotation in baseball, the Mariners face concerns about injuries and performance drops among key pitchers, which could lead to a frustrating 2025 season.
