Mariners Moving to Six-Man Rotation Amid Grueling Schedule
Seattle adopts a six-man rotation to manage a 16-games-in-17-days stretch, with the format potentially continuing past June 15.
The Mariners will transition to a six-man rotation after Sunday's game, when Bryce Miller starts and Luis Castillo serves as piggyback pitcher. The move is driven by a stretch of 16 games in 17 days beginning Friday. Management will reassess the rotation structure on June 15, the team's next scheduled off-day. Both Miller and Castillo had expressed frustration over a perceived lack of communication, prompting direct conversations with the manager, pitching coach, and front office.
