In the credits, also look for "best infielder" - Felix Mantilla. Mantilla was one of the earliest black players in the major leagues with an 11 year career as an infielder. He scored the winning (and only) run in a Braves - Pirates game in 1959 in one of the oddest plays in major league history involving him, Hank Aaron and Joe Adcock.
