Frank Robinson, who became the first black manager in MLB when he took over the Cleveland Indians:
Robinson made his debut as the majors’ first black manager with the Cleveland Indians on April 8, 1975, 28 years after Jackie Robinson (no relation) first took the field with the Dodgers. Rachel Robinson, Jackie Robinson’s widow, threw out the ceremonial first ball.
Frank Robinson, who was still an active player, punctuated the historic occasion by hitting a home run in his first at-bat, as the designated hitter, leading the Indians to a 5-3 victory over the Yankees.
