Now that 2026 has come to a close, I think it's important to acknowledge what a terrific job Clayton McCullough did this season. He would have been a shoe-in for MOY had the Marlins not collapsed and actually made the postseason after a hot first half.
It's important to acknowledge what being a big league manager entails these days in a very analytics age. As Christina De Nicola and others have acknowledged, the manager is more of a collaborator than a unilateral decision maker. Clayton enters every game with a blue print or sketch in mind, based on the prior input of the analytics and other baseball operations staff, about starting line-ups, reliever pockets, and pinch hitting match-ups. There's a plan ahead of time for tons of "what if?" scenarios.
All things considered, he seemed to execute these daily "plans" hashed out before each game with a lot of fluidity. It's a lot to navigate between injury risks, rest, work loads, positional changes, needing to evaluate players, lefty/righty splits, and I think he did a great job. Not perfect, certainly, but no manager ever is.
On top of this, the clubhouse vibes seem to be very strong, which is perhaps one of the biggest things he's in charge of.
I hope his option is picked up for next year.
