In October baseball, legends are made, hearts are broken, and fan bases convince themselves they’re destined for greatness. Some teams have the history to back it up. Others? Well, they think the Fall Classic calls their name every year.
Whether based on a few memorable postseason runs or pure delusion, these 14 MLB fan bases walk into every season believing that October is already circled in red. Let’s rank the most confident (and sometimes comically overconfident) fan bases that act like the postseason was made just for them.
14. Milwaukee Brewers

The Brewers haven’t won it all, but that doesn’t stop their fans from thinking every roster tweak is the final piece of a championship puzzle. They strongly believe destiny will take over if they sneak into the playoffs.
13. Toronto Blue Jays

Blue Jays fans still ride the high of the early ’90s glory days and Joe Carter’s home run like it happened last week. Every season feels like it has to be their return to October dominance, no matter how mid the team looks by July.
12. St. Louis Cardinals

Cardinals fans treat playoff baseball like a birthright passed down through generations. Even in a down year, there’s an unshakable belief that the “Cardinal Way” will deliver when it matters most.
11. San Francisco Giants

Three rings in the 2010s gave this fanbase a permanent October complex. Even when the team hovers around .500, Giants fans see themselves as a sleeping playoff monster.
10. Houston Astros

Say what you want about the controversies, but Astros fans fully expect to be playing deep into October. In their minds, October without Houston isn’t even real baseball.
9. Atlanta Braves

The Braves have the talent to back it up, and their fans know it. There’s a confident swagger in Atlanta that says, “We’ll see you in the NLCS, at minimum.”
8. Boston Red Sox

Red Sox Nation can go from “fire everyone” to “we’re winning it all” in weeks. Once September hits, they flip a switch and start talking like they’ve already booked the duck boats.
7. Chicago Cubs

One ring in 2016 erased a century of pain and replaced it with some serious October confidence. Cubs fans expect to be in the mix, and something feels off to them when they’re not.
6. Philadelphia Phillies

The Phillies could lose 10 straight, and their fans would still believe they’re built for the postseason. Once the calendar hits October, the vibes shift and the confidence skyrockets.
5. New York Mets

Mets fans may be perpetually stressed, but they believe October belongs to them, especially before Opening Day. It’s an annual ritual of expecting the best and bracing for chaos.
4. Chicago White Sox

Despite limited recent success, White Sox fans talk like they’re built for October battles. That South Side swagger is real, even if the postseason appearances aren’t.
3. Los Angeles Dodgers

Dodgers fans consider October an extension of the regular season. Anything less than a World Series feels like failure, and they expect dominance every year.
