Some might call it exploitation. Some might call it genius. Wherever you land, the St. Louis Browns' use of 3'7" Eddie Gaedel in the second game of a double-header is something that will never be seen again in sports. Sporting the jersey number "1/8" Gaedel led off the game for the Browns and (not shockingly) drew a four pitch walk. He was pinch run for, and never again appeared in a Major League game. His 1.000 OBP remains tied for the best in baseball history, and Gaedel's autograph is more valuable than Babe Ruth's. No, seriously.
