Burleigh Grimes never shaved on days he pitched, because the slippery elm he chewed to increase saliva irritated his skin, so he always had stubble on his face when he took the mound. That led to his nickname, Ol' Stubblebeard.

He wasn't just known for his stubble, he was also known as one of the toughest competitors to ever take the mound. His scowl would have made Randy Johnson's look like a smiley face, and when it was time to give someone an intentional walk, he was known to throw four pitches near the batter's head.

Grimes is a Hall of Famer, but certainly not for his one and half years with the Cubs (1932-33). He was 9-17 for the Cubs, but was a five-time 20-game winner before that. (The Cubs got him from the Cardinals for Hack Wilson, who to be totally fair, also didn't have much left in the tank.)

Ol' Stubblebeard was the last legal spitball pitcher in the majors. When he retired, so did that pitch. (Wink, wink. Right, Gaylord Perry?)
