The Miami Marlins have appointed Clayton McCullough, previously the Los Angeles Dodgers' first base coach, as their new manager for the 2025 season. McCullough, 44, replaces Skip Schumaker, who parted ways with the team after a disappointing 62-100 record in 2024. This will be McCullough's first major league managerial position, although he has extensive experience in the Dodgers organization and in the Blue Jays' minor-league system. The Marlins, known for their struggles in recent years, have not finished higher than third in the NL East since 2020 and are in the midst of a rebuilding phase. With a focus on developing young talent, McCullough will have to navigate the challenges of a team that ranked poorly in pitching and offense last season. Despite the team's recent history, McCullough's familiarity with the Marlins' assistant general manager, Gabe Kapler, may provide a foundation for success.
