In 1947, major league baseball experienced its first measure of integration when the Brooklyn Dodgers brought Jackie Robinson to the National League. While Robinson’s breakthrough opened the gates of opportunity for African Americans and other minority players, the process of integration proved slow and uneven. It was not until the 1960s that a handful of major league teams began to boast more than a few Black and Latino players. But the 1971 World Championship team enjoyed a full and complete level of integration, with half of its twenty-five-man roster comprised of players of African American and Latino descent. That team was the Pittsburgh Pirates, managed by an old-time Irishman.
