Charles Schultz created The Peanuts cartoon strip many moons ago and thus the legend of Charlie Brown grew as a pop icon. Charlie Brown is often seen playing football or baseball in Schultz's pieces, but there lives real-life Charlie Brown's (actually a handful of them) who played professional baseball.
Charlie Brown #1 played in the Philadelphia Phillies organization from 1989-1991 as a light-hitting outfielder. He never made it past Double-A. Charlie Brown #2 was a pitcher in the New York Yankees farm system from 1992-1997. He also never made it above Double-A. Charlie Brown #3 played one season in the Pittsburgh Pirates organization in 1946.
Then there was one lucky cat who made it to the bigs, that would be Charlie Brown #4, and it was as a Cleveland Spider all the way back in the 1897. Plenty of other players were named Charles Brown, but those 4 are the only ones that went by "Charlie".
