Robert Bernard Dillinger (September 17, 1918 – November 7, 2009) was an American professional baseball third baseman who appeared in 753 games in the major leagues (MLB) from 1946 through 1951 for the St. Louis Browns, Philadelphia Athletics, Pittsburgh Pirates and Chicago White Sox. Dillinger's six years in the major leagues showcased his batting ability (he led the American League in hits in 1948 with 207 and batted over .300 four times) and his speed (he was the Junior Circuit's stolen base champion for three consecutive years, 1947 through 1949, with 82 total thefts), but poor defense and a perceived lackadaisical attitude resulted in a premature end to his big-league tenure. He threw and batted right-handed, stood 5 feet 11 inches (1.80 m) tall and weighed 170 pounds (77 kg).
