Eddie Gaedel

This caught my eye at Bob Dearborn's The Old Disc Jockey's Almanac. On this day in 1951...

"Bill Veeck, owner of baseball's St. Louis Browns, sent Eddie Gaedel, a 3'7" midget, to the plate to pinch-hit. Because of the tiny strike zone of someone of Gaedel's physical stature, he was walked on four consecutive pitches. His one appearance in the major leagues ended abruptly when he was replaced at first base by a pinch-runner. Gaedel's jersey, bearing the uniform number "⅛," is displayed at the Baseball Hall of Fame."
