Some MLB fanbases are just built differently. Whether it’s the history, the swagger, or the nonstop chirping on social media, these fans manage to stir the pot without even trying.
They don’t need a championship every year to stay relevant in the minds of rivals. Just their presence alone is enough to get other fans riled up—welcome to the rent-free zone.

Brewers fans may fly under the radar, but somehow, they always spark debate. They’ve mastered the underdog energy with just enough confidence to get under people’s skin.

Braves fans have a lot of pride and are never shy about showing it. Whether it’s a winning streak or a home run trot, they know exactly how to push buttons.

Padres fans talk with the energy of a dynasty, and it drives other fanbases absolutely nuts. Even when the team struggles, they still talk like the parade route is being finalized.

Mets fans don’t even need to win to stay in the conversation. The mix of chaos, confidence, and Twitter meltdowns keeps them front and center in everyone’s mind.

Cardinals fans act like they invented the unwritten rules of baseball. That whole “Best Fans in Baseball” thing? Yeah, that slogan lives rent-free all by itself.

Astros fans have fully embraced the villain arc. The more people boo them, the louder they cheer—and that attitude keeps them lodged in the heads of fans everywhere.
