Miami Marlins Manager Clayton McCullough: Building a Winning Culture | Jupiter Magazine (2026)

Imagine leaving a storied franchise to take the helm of a team that just lost 100 games. Sounds crazy, right? But that’s exactly what Clayton McCullough did when he became the manager of the Miami Marlins. And this is the part most people miss—it wasn’t just about the job title. In an exclusive interview with Jupiter Magazine, McCullough reveals the bold vision and personal philosophy that led him to this decision, and why he believes the Marlins are on the brink of something special.

Baseball managers are no strangers to tough calls—whether it’s sending a runner or pulling a struggling pitcher. Yet, McCullough’s choice to leave the Los Angeles Dodgers, where he served as first base coach, for a team that seemed to be in disarray, raises eyebrows. But here’s where it gets controversial: Was it a risky gamble or a calculated move? McCullough insists it was neither. “It was about aligning with people who shared my vision and philosophy,” he explains. “I knew Miami would present unique challenges, but that’s what made it exciting. It wasn’t just about the 30 managerial jobs in the league; it was about the right time and place.”

And the results? They speak for themselves. In his first season, the Marlins defied expectations, dropping only 83 games in 2025 and securing third place in the National League East. They even flirted with a Wild Card spot, winning seven of their last ten games. Peter Bendix, President of Baseball Operations, is thrilled with the team’s trajectory under McCullough’s leadership. But McCullough’s pride isn’t just in the numbers—it’s in the team’s resilience. “We started with a walk-off win, and even in our toughest moments, this team never stopped competing,” he says. “That kind of toughness is what it takes to win in the postseason.”

But here’s the real question: Can the Marlins sustain this momentum? McCullough’s journey to this point is as compelling as the team’s turnaround. Born in Greenville, North Carolina, baseball was in his DNA. His father, Howard, a college coach turned Boston Red Sox scout, laid the foundation. Yet, McCullough’s own playing career was less than stellar. “I wasn’t a very good player,” he admits candidly. After a few years in the minors, he pivoted to coaching, finishing his degree at Eastern Carolina University and volunteering as a coach. This decision, he says, was about staying in the game he loved, even if it wasn’t on the field.

His path to the Marlins was anything but linear. From coaching in the Toronto Blue Jays organization to meeting his wife, Jill, while working for the Lansing Lugnuts, McCullough’s life has been a blend of baseball and family. Jill, whose father was a pilot, understands the challenges of a partner often on the road. “Communication is key,” she says. “We make sure we’re always connected, whether through FaceTime or knowing when we’ll see each other next.” Their three children—Carson, Kyle, and Quinn—have adapted well to the baseball lifestyle, thanks in no small part to Jill’s unwavering support. “She’s a superhero,” McCullough says gratefully.

Managing the Marlins has brought McCullough closer to home, both literally and figuratively. Jill appreciates the shorter periods apart, and the kids can easily visit their dad at games in Miami. “He’s a great dad,” Jill says. “When he’s home, he’s fully present—whether it’s attending school events or taking the kids to Disney.”

Looking ahead to the 2026 season, McCullough is focused on building on the team’s success. “We started with a blank slate,” he reflects. “There’s freedom in that—we’re not bound by tradition. We’re creating something new, and that’s exciting.” The Marlins are buying into his vision, hungry to improve every day. While no one knows what the future holds, McCullough’s philosophy is clear: “Let’s just worry about today. We’re in this together, and what others say doesn’t define us.”

But here’s the controversial part: Can a team with such a recent history of struggles truly become champions? McCullough believes they can, and he’s not alone. The question now is, do you? Let us know in the comments—is McCullough’s vision enough to turn the Marlins into contenders, or is this just another rebuilding phase? The debate is open, and the stakes have never been higher.
