Richard Anthony Allen (born March 8, 1942, in Wampum, Pennsylvania) is a former Major League Baseball player. He played first and third base and outfield in Major League Baseball and ranked among his sport's top offensive producers of the 1960s and early 1970s. Most notably playing for the Philadelphia Phillies and Chicago White Sox, he led the American League in home runs twice, and led both leagues in slugging average (the AL twice) and on base percentage. His .534 career slugging average was among the highest in an era marked by low averages. He won the 1964 National League Rookie of the Year and 1972 AL MVP. He also spoke his mind, combatted racism, and bucked organizational hierarchy. Sabermetrician Bill James rated Dick Allen as the second-most controversial player in baseball history, behind Rogers Hornsby. James, not letting facts get in the way of a good story, also opined that Allen "did more to keep his teams from winning than anybody else who ever played major league baseball."
His older brother Hank was a reserve outfielder for three AL teams, and his younger brother Ron was briefly a first baseman with the 1972 St. Louis Cardinals.
Allen hit a baseball with an authority Philadelphia fans had not seen since Chuck Klein and Jimmie Foxx. The Phillies saw his potential immediately and signed him in 1960 for a large $60,000 bonus. His career got off to a turbulent start as he faced racial harassment while playing for the Phillies' minor league affiliate in Little Rock; residents staged protest parades against Allen, the local team's first black player. Nevertheless, he led the league in total bases.
