Not every MLB team enjoys a national fanbase. Some are regional royalty—beloved by the locals but largely ignored, dismissed, or even mocked outside their home state.
Whether it’s due to a lack of postseason relevance, small market size, or just plain indifference from the rest of the country, these teams are the definition of “if you know, you know.” Here are 15 MLB franchises that are only truly adored within their state borders.
15. Colorado Rockies
The Rockies are like that local diner everyone swears by—but only if you’re from the neighborhood. Most baseball fans forget they exist outside of Colorado until someone hits a home run into the mountains.
14. Detroit Tigers
In Michigan, the Tigers are a treasured tradition. Outside of it, they’re mostly a reminder of how long it’s been since 1984. Hey, at least they’re good this year!
13. Arizona Diamondbacks
Locals in Arizona ride hard for their Snakes. The rest of the country barely remembers that they won a World Series, and they probably couldn’t name more than two players on the roster.
12. Minnesota Twins
Twins fans show up through thick and thin, especially in the Land of 10,000 Lakes. But nationally, they’re treated like baseball wallpaper—there, but not commanding attention.
11. Miami Marlins
In South Florida, there’s a small but proud Marlins following. Outside of it, most people assume the stadium is empty for a reason.
10. Milwaukee Brewers
Wisconsin folks love their Brewers like they love their cheese curds. Outside the state, most people can’t decide if they’re a real threat or just a great name for a beer league team.
9. Cincinnati Reds
Reds fans live and breathe baseball history. But outside Ohio, that history feels a little dusty, and the present doesn’t help their case.
8. Kansas City Royals
In Missouri (and Kansas), the Royals are a point of pride, especially post-2015. Elsewhere, they’re usually slotted into a forgettable Wednesday afternoon game on MLB.TV.
7. Pittsburgh Pirates
Steel City fans cling to nostalgia and the hope of brighter days. But nationally, the Pirates are more known for bargain-bin payrolls than winning baseball.
6. Seattle Mariners
In the Pacific Northwest, Mariners fans are passionate and patient. Unfortunately, most other fans forget they exist until a late-night West Coast highlight reel.
5. Cleveland Guardians
Cleveland fans are loyal to a fault, but the Guardians don’t move the needle nationally. To most others, they’re a team with a weird new name and not much else.
4. Oakland Athletics
In the Bay Area, A’s fans wear their green and gold like a badge of honor — for now. Everyone else mostly sees a sad stadium and a team about to be relocated.
3. Tampa Bay Rays
Tampa fans appreciate their scrappy, analytics-driven squad. But they still can’t convince the rest of the country—or even their city—to care.
2. Chicago White Sox
South Side Chicago loves their Sox, but the national spotlight rarely makes it past Wrigley Field. They’re often the “other” team in town than the rest of the country.

1. Baltimore Orioles
Charm City is buzzing again with Orioles pride. But outside Maryland, most fans now remember they’re not supposed to be bad anymore.
