WHAT IS UMPIRE NINJA?
It’s a mindset. A movement. A mustache.
Umpire Ninja is more than flips and showmanship. It’s about taking care of your body, learning how to move, how to fall, how to lead — and how to make baseball more fun for the fans, the players, and the people behind the plate.
Started by Seth Markham, who trained in both baseball and parkour, this brand is built on the belief that performance and personality can go hand-in-hand. Whether you're calling plays or just calling attention, Umpire Ninja is here to bring energy, creativity, and joy back to the game.
