Baseball breeds a certain level of monotony. There are 28 guys on a roster, many of whom quietly plod away at their craft for 162 games a year. That's fine, but it's not fun.

Every once in a while, however, MLB spits out a gem of a player — an individual so captivating you can't look away. Some guys are polished in the spotlight, but unhinged behind the scenes. Others have no filter, happy to spit venom on the biggest stages, unafraid of consequences.

This page houses my MLB Villains series, where we hone in on baseball's modern madmen, why they're so crazy, and how their unorthodox dedication to their craft puts them among the sport's most memorable figures. Each player is a special brand of crazy, and we love them all for every ounce of fussiness, flavor, and foible.
