Ask anyone in a bar on Boylston Street about the Sox, and they’ll start with 2004. It’s the default setting. The Dave Roberts steal, the Big Papi walk-offs, the "bloody sock"—it's the holy trinity of Boston sports. But honestly, if you look at the full scope of red sox postseason history, that 86-year drought was actually the anomaly, not the rule.
Before they became the hard-luck losers of the 20th century, they were the first real dynasty of the 21st. Wait, I mean the early 20th.
Boston won the first-ever World Series in 1903 back when they were still the Americans. They didn't just win; they dominated. They grabbed four more titles between 1912 and 1918. Then, well, we all know the story about the guy they sold to New York. The dry spell that followed wasn't just about bad luck. It was about a series of increasingly bizarre, heart-wrenching ways to lose on the biggest stage possible.
The Era of "Almost" (1946–1986)
Most fans who lived through the lean years remember the 1975 World Series as the pinnacle of "what if." Carlton Fisk waving that ball fair in Game 6 is arguably the most famous home run in the history of the sport.

It didn't matter. They lost Game 7 anyway.
That’s basically the theme of the mid-century red sox postseason history. They would get to the mountain top, look at the view, and then slip on a banana peel. In 1946, Enos Slaughter’s "Mad Dash" caught them sleeping. In 1967, the "Impossible Dream" season ended with Bob Gibson simply being too good for human hitters to handle.
Then came 1986.
If you want to understand the psyche of an older Sox fan, you have to understand the Mookie Wilson grounder. It wasn't just Bill Buckner's fault—the pitching staff blew a two-run lead with two outs and nobody on in the 10th inning. It was a total organizational collapse. It felt like the universe was actively conspiring against them. Honestly, at that point, people really did believe in the Curse.
Why 2004 Changed Everything
The 2004 ALCS is the only time in MLB history a team has come back from a 3-0 deficit to win a seven-game series. It shouldn’t have happened. The Yankees were up 4-3 in the 9th inning of Game 4 with Mariano Rivera—the greatest closer to ever breathe—on the mound.
One walk. One stolen base. One single by Bill Mueller.
The momentum shift was so violent it felt physical. After David Ortiz ended Game 4 and Game 5 with walk-off hits, the Yankees looked like they’d seen a ghost. By the time Curt Schilling took the mound in Game 6 with a literal tendon sewn into his ankle, the outcome felt weirdly inevitable.
They swept the Cardinals in the World Series. Just like that, 86 years of baggage evaporated.
The Modern Powerhouse (2007–2025)
Since breaking the seal, the Red Sox haven't behaved like the "lovable losers" anymore. They’ve been ruthless.
In 2007, they swept the Rockies. In 2013, they won for a city reeling from the Boston Marathon bombing, led by an aging but still terrifying David Ortiz. 2018 was perhaps their most complete team ever—108 wins in the regular season and a near-flawless run through the playoffs.

Even the recent years have had their moments. Take 2021. Nobody expected them to do anything, yet they knocked out the 100-win Rays and pushed the Astros to six games in the ALCS.
Recent Matchups with the Bronx
Interestingly, the rivalry with New York has shifted. For decades, the Yankees owned the postseason. But since 2004, the Sox have actually won most of their playoff meetings.
- 2018 ALDS: Sox won 3-1 (including a 16-1 blowout in the Bronx).
- 2021 Wild Card: A 6-2 win at Fenway that felt like a party.
- 2025 Wild Card: The Yankees finally got some revenge, winning the series 2-1.
It's a back-and-forth affair now. No longer a hammer and a nail.
Realities of the Numbers
If you’re looking at the raw data of red sox postseason history, the franchise currently sits with 9 World Series titles. That’s tied for third all-time.
People forget that between 1912 and 1918, they won four championships in seven years. If you count their 21st-century run, they’ve won four more in the last 20 years. Basically, the Red Sox are a team of "feast or famine." They either don't make the playoffs at all, or they go in and wreck the place.
There is very little middle ground in Boston.
Common Misconceptions
A lot of people think Ted Williams was a postseason failure. The truth is he only ever got one shot—1946. He played with an injured elbow and didn't hit well, sure, but the "choker" label is a bit much for a guy who only had 25 playoff at-bats in a 19-year career. Different era, different rules.
Another thing? The 1978 "Bucky Dent" game wasn't technically the postseason. It was a 163rd regular-season tiebreaker. But in the hearts of New Englanders, it counts as one of the darkest playoff moments ever recorded.
How to Dig Deeper into Sox Lore
If you really want to master the nuances of this team's history, you shouldn't just look at the box scores. You have to look at the context of the city.
- Watch "Four Days in October": It’s the definitive documentary on the 2004 comeback. It captures the tension better than any article ever could.
- Visit the Royal Rooters Club: If you ever go to Fenway, check out the memorabilia. It puts the 1903 and 1912 wins in perspective.
- Study the 1967 Season: Often called the most important season in Red Sox history, even though they lost. It saved baseball in Boston.
The history of this team isn't just a list of wins and losses. It's a map of New England's collective blood pressure. From the early dominance of Cy Young and Tris Speaker to the clutch heroics of Steve Pearce and Rafael Devers, the postseason is where this team defines itself.

To truly understand the current state of the AL East, you have to acknowledge that the Sox are no longer underdogs. They are an organization that expects to win, and more often than not in this century, they do.
