Diamondbacks pitcher Merrill Kelly brings a kid’s Christmas routine to his offseason, and it starts with Legos

Merrill Kelly has always approached baseball like a craft, something you practice until the repetition becomes instinct. In an MLB feature, the Diamondbacks right-hander traced that mindset back to Christmas mornings in Phoenix, when he would wake up very early and settle into a familiar off-field ritual long before he ever wore a Major League uniform.

Kelly’s pastime now is Lego building, an activity he describes as part hobby, part tradition, and part reminder of how he learned to enjoy the slow work of assembling something piece by piece. In the interview, he points to the sense of routine from those childhood holiday mornings as the root of why Legos still feel “right” to him when he wants to get away from baseball’s calendar demands.

Baseball players are often asked how they manage mental energy across a long season, especially when the grind is replaced by uncertainty in the offseason. Kelly’s answer, at least here, is not about technology or training plans. Instead, it is about choosing a pastime that requires attention, patience, and the willingness to keep working when the result is not immediate.

That matters in the Diamondbacks’ context because pitchers carry a different kind of workload than most positions. Starters and rotation members must be prepared on a specific schedule, but they also need to stay mentally steady between starts. An offseason routine that pulls a player into something structured and engrossing can help preserve that steadiness, even when spring training and the next bullpen session are not on the horizon.

Kelly’s comments also highlight something quieter about elite performance, the way comfort with repetition can translate across sports. Lego building is, by design, repetitive, but it also offers incremental payoff as builds come together. For a pitcher, that balance mirrors what coaches ask for day-to-day: perform small tasks cleanly, trust the process, and let results arrive when they are supposed to.

The feature is light on baseball statistics and focused on personal life rather than performance. But the underlying theme is familiar to anyone who follows the Major Leagues: routines, even ones that look unrelated to baseball, often end up shaping how players handle pressure. Kelly’s Christmas tradition, as he describes it, becomes a small roadmap for how he stays centered during the parts of the year when the sport’s structure is at its lowest.

For fans, the story offers a human window into the person behind the pitch. For the team, it reinforces a broader clubhouse truth, that players do not only prepare their bodies for the season, they also keep their minds busy in ways that match their temperaments. Watching how Kelly integrates that kind of offseason calm into the regular-season build will be one of the steadier storylines to track as Arizona looks for consistent pitching in the months ahead.
