His real name was Nicholas Dominic Dallessandro, but he went by his middle name of Dom. Despite the sound of it, his teammates didn't call him Dim Dom because he was stupid. It was because of his diminutive height. He was only 5'6". Dim Dom played outfield for some pretty mediocre Cubs teams in the early 40s, and had one good season in 1944 (hitting .304).

Unfortunately for Dom, his timing wasn't the best. After his best season, he was called into the military in early 1945, and missed the only Cubs World Series of the decade. He did return to play a few more seasons for the Cubs, but was shipped out to the minor league team in Los Angeles (photo) after the 1947 season. He finished his professional baseball career there.
