The Quantum InsightsMiami Marlins are hiring Los Angeles Dodgers first base coach Clayton McCullough as their new manager, multiple reports said Sunday.

McCullough, 44, had been with the Dodgers in a variety of roles since 2014 but has prior managing experience in the Toronto Blue Jays' minor league system from 2007-2014.

He compiled a 402-357 record across various stops in the Gulf Coast League, Class-A and Advanced-A levels.

While with the Dodgers, he overlapped with Gabe Kapler, the former Philadelphia and San Francisco manager who's now Miami's assistant general manager.

McCullough is credited with improving Shohei Ohtani's running game -- he became the first player to have a 50-50 season in 2024, with 59 stolen bases and 54 home runs. McCullough pitched to Mookie Betts in the 2023 Home Run Derby, when Betts described him as his "favorite coach ever."
