You might not have wondered which fans of Major League Baseball have the worst grammar, but Grammarly did, and they went on a mission to figure it out. To do so, they went through the comments of team sites and analyzed how many mistakes per hundred words fans of each team made.

The findings are pretty interesting. It turns out that Marlins’ fans make only 1.39 mistakes per 100 words. Cardinals fans make almost twice the number of mistakes that those of the Marlins do, chalking up 2.20 mistakes per hundred words. Yankees fans aren’t much better than the good people of St. Louis — they generally make over two mistakes per hundred words as well. And there’s something in the water in Ohio, because both fans of the Cleveland Indians and the Cincinnati Reds make fewer mistakes than fans of 27 other teams.

Here’s the full breakdown. And if you’re interested, here’s how the fanbases of NBA teams do when it comes to speaking good.
