A World Series side patch adds the official World Series logo to the side of the cap, turning a regular crown into an instant standout. It’s one of the most recognizable details in MLB headwear, and a quick way to tell you’re looking at a hat that's apart of baseball’s biggest event.
You’ll see this look most often on a New Era 59FIFTY fitted, 9FIFTY snapback, and 9FORTY A-Frame hats, with the team logo on the front and an World Series side patch stitched on the side panel. This combination is popular because it keeps the hat clean up front while adding a clear “postseason” detail for collectors and fans.
Historically, the MLB added the World Series logo to player caps in 1996, turning it into a simple way to mark the season’s biggest moment. In 2016, the on-field patch placement shifted to the opposite side to make room for the New Era flag. The side patch placement can help identify which era a hat is referencing.
Most World Series side patches are year-specific and follow the official branding for that season, which is why collectors often search by team + year + patch. Some hats use the standard World Series patch, while others feature a “World Series Champions” patch, which is typically the version collectors target when they want the “winner” detail.
Styling tip: match one color from the patch (outline, text, or accent color) to your sneakers or hoodie, and keep the rest of the outfit neutral so the World Series patch fitted hat stands out without clashing.
