MIAMI – The Miami Marlins today announced the hiring of Clayton McCullough as Major League Manager.

McCullough, 44, becomes the 17th Manager in Marlins history. He recently concluded his 10th season with the Los Angeles Dodgers organization (2015-24), including his fourth campaign as First Base Coach, where he was a member of the coaching staff that won the 2024 World Series title.

"We are thrilled to introduce Clayton McCullough as Manager of the Miami Marlins following an extensive search," said Bruce Sherman, Miami Marlins Chairman and Principal Owner. "Clayton joins our organization following a World Series Championship season and brings a strong pedigree of winning. His love of the game, ability to build meaningful relationships, and new leadership will guide our organization into an exciting new era. With roots already in South Florida, we are excited to welcome Clayton along with his wife Jill and their children to the Marlins organization.”

“We couldn’t be more excited to welcome Clayton and his family to the Marlins,” said Peter Bendix, Miami Marlins President of Baseball Operations. “Throughout our process, his character, care for people and culture, passion for player development, and desire to win stood out and make him a perfect fit for our organization. He has an impressive track record of success, building relationships, and bringing positive energy every day. It’s clear that Clayton’s values and vision align perfectly with ours, and we are ready to begin working on the next exciting chapter for our club.”

“It is an honor to be introduced as the Manager for the Miami Marlins, and I would like to thank Bruce, Peter, and the entire organization,” said McCullough. “Following an incredible past few weeks, it is exciting to end the year by finding the right opportunity for me and my family. We have called South Florida home for the last 10 years, and now I get to lead the Marlins franchise forward with a culture that is built on determination, focus, and care.”

Originally hired as Minor League Field Coordinator by the Dodgers before the 2015 season, McCullough held that position until his promotion to First Base Coach ahead of the 2021 campaign. He also played a key role during the 2020 pandemic-shortened season as he oversaw the Dodgers’ operation at their alternative site at the University of Southern California. Before joining the Dodgers, McCullough spent nine seasons in various coaching roles in the Toronto Blue Jays organization (2006-14), including five Postseason appearances, two Manager of the Year awards, and a 402-367 (.523) record in seven campaigns as a Minor League Manager. During his tenure as manager in the Blue Jays system, McCullough led his club to a winning record in six of the seven seasons.

The Jupiter, Fla. resident began his coaching career with the Rookie-level Pulaski Blue Jays (2006) and earned his first managerial assignment the following season with the Rookie-level Gulf Coast League Blue Jays (2007). He then managed Single-A Lansing (2008-09) to a Postseason berth in his first season, guided High-A Dunedin (2010-11) to consecutive playoff berths, and won consecutive championships with Short Season-A Vancouver (2012-13). He was named the Florida State League Manager of the Year in 2011 and the Northwest League Manager of the Year in 2012.

Originally selected by Cleveland in the 22nd round of the 2002 First-Year Player Draft out of East Carolina University, the Oxford, N.C. native appeared in 104 games over four seasons in the Cleveland organization. McCullough’s father, Howard, has held various roles in Major League scouting departments with the Boston Red Sox, Arizona Diamondbacks, Seattle Mariners, and Kansas City Royals.

The Miami Marlins begin the 2025 regular season on Thursday, March 27 vs. the Pittsburgh Pirates at 4:10 p.m. at loanDepot park. For more information on the Miami Marlins, please visit Marlins.com and MarlinsBeisbol.com.
