Baseball is America’s pastime, but let’s be real: part of the fun is watching fanbases lose all sense of decorum when their team is on the field. Some crowds are known for their passion, others for their hospitality, and then there are those who make opposing players and fans feel like they just walked into a medieval battle. If you’ve ever attended an away game and felt like you were in enemy territory, you know exactly what we’re talking about.
Here’s our ranking of the 15 most disrespectful MLB fanbases to opposing teams—where heckling is an art form and sportsmanship sometimes takes a backseat to pure, unfiltered hostility.
15. San Francisco Giants
Not always the loudest, but if you’re a Dodgers fan rolling into Oracle Park, you’d better have thick skin. The Giants faithful never forget a grudge, and they’ll make sure you don’t either.
14. Houston Astros
After the sign-stealing scandal, Astros fans have taken on a bit of a “villain arc” persona. Opposing teams get an earful about how Houston is “still winning,” even when their team isn’t.
13. Cleveland Guardians
The fanbase isn’t huge, but they make up for it with Midwestern passive-aggressiveness and an ability to remember every single slight against their team. Bonus points for how much they still resent Yankees fans.
12. Minnesota Twins
It’s the passive-aggressive Midwest hospitality mixed with deep-seated baseball pettiness. They’ll offer you a hotdish with one hand and a scathing remark about your team’s pitching with the other.
11. New York Mets
They hate their own team almost as much as they hate yours, and they aren’t afraid to remind you of both. If you’re in Queens wearing opposing colors, prepare for some colorful language.
10. St. Louis Cardinals
“Best fans in baseball” can also be some of the most condescending. They’ll remind you of their 11 rings every chance they get, and if you dare criticize their team, you must not “understand the game.”
9. Chicago Cubs
Wrigleyville is a great place for a beer—unless you’re cheering for the wrong team. Cubs fans are rowdy, loyal, and not above reminding you of your team’s worst moment in excruciating detail.
8. Los Angeles Dodgers
Dodger Stadium can be electric, but if you’re an opposing fan in the outfield seats, good luck. This crowd doesn’t just heckle—you might leave knowing deeply personal flaws you didn’t even realize you had.
7. Toronto Blue Jays
Canadians? Disrespectful? You bet. The Rogers Centre is basically a house of heckling, and if you dare wear Yankees gear in the building, they’ll make you question all your life choices.
6. Milwaukee Brewers
Between the beer, the tailgating, and a fanbase that lives and dies by their squad, Milwaukee isn’t the friendliest place for visiting teams. And let’s be real—when they get going, the “Roll Out the Barrel” chants start to feel a little menacing.
5. Philadelphia Phillies
You knew this was coming. Phillies fans booed Santa Claus—so imagine what they’ll do to your team. Philly doesn’t just dislike opposing teams; they relish making them miserable.
4. New York Yankees
The Bronx is ruthless. Yankees fans have perfected the art of trash talk, and if your team isn’t on their level (spoiler: most aren’t), they’ll let you know. Bonus points for the unrelenting “27 rings” argument.
3. Chicago White Sox
South Side energy is different. Sox fans are aggressive, unfiltered, and proud of it. If you step into Guaranteed Rate Field as an opposing fan, prepare to be verbally demolished.

2. Boston Red Sox
Fenway Park is a historic gem—but if you’re rooting for the wrong team, it might feel like a medieval torture chamber. Red Sox fans hold grudges like it’s their job, and they don’t believe in letting an opposing fan enjoy a game in peace.

1. Oakland Athletics
It might surprise you, but A’s fans are some of the rowdiest in the game. Even with their team’s uncertain future, they’re loud, they’re proud, and they will absolutely let the opposing dugout know they’re unwelcome. There’s something extra special about a heckle from a fan base that’s been through it all and still refuses to go quietly.
