The Mets have committed 46 errors so far in 2015, but their fans may have a propensity for making a different kind of error.

Mets fans make 13.9 spelling, grammar or punctuation mistakes per 100 words -- more than any other MLB fanbase, according to the Wall Street Journal and Grammarly, an automated proofreading website.

Grammarly looked at all 30 official MLB team sites from May 11 to May 15 and analyzed the top 150 comments from each site -- averaging more than 10,000 words for each team -- using an "editor to detect grammar, spelling and punctuation errors in each comment," according to the website. They then verified the errors using their proofreaders and used those totals to calculate the average per 100 words.

Yankees fans aren't much better at using proper grammar, ranking 26th overall with 12.1 errors per 100 words.

Cleveland Indians fans have the best grammar of any fanbase, averaging just 3.6 errors per 100 words. Overall, fans of National League teams (7.8 errors per 100 words) have slightly better grammar than their American League counterparts (8.3).
