Defenders of the Diamond, Assemble! Minor League Baseball and Marvel Entertainment have partnered on an exciting three-year program called “Marvel’s Defenders of the Diamond” featuring 96 different Minor League Clubs across all four levels. The fun began during the 2022 MiLB season with each Club hosting at least one Marvel theme night at their ballpark involving popular Marvel Super Hero character appearances, special Marvel-themed uniforms, custom Minor League Baseball-themed comic books and entertaining Marvel-themed activities and promotions throughout the game too.

As part of the Marvel’s Defenders of the Diamond series, Marvel animators have reimagined logos for all participating clubs.

Available in fitted sizes 6-7/8 to 8.

100% Polyester.

The Great Lakes Loons are the High-A Affiliate of the Los Angeles Dodgers.
