Look: Marlins fans have the best grammar in MLB, Cardinals the worst

St. Louis Cardinals fans need to brush up on their grammar skills.

The folks at Grammarly scoured the comment section of each MLB team's SB Nation blog to determine how fan bases rank when it comes to grammar, spelling, sentence structure, and punctuation.

Miami Marlins fans came out on top with an average of 1.39 mistakes per 100 words, while the Cardinals ranked last with 2.20 mistakes per 100 words. Ohio fans did very well, with the Cleveland Indians and Cincinnati Reds finishing second and third, respectively.
