On April 22, 1957, John Irvin Kennedy becomes the first African American player on the Philadelphia Phillies, fully integrating the National League 10 years after Jackie Robinson broke Major League Baseball's color barrier. In the eighth inning of a 5-1 loss to the Brooklyn Dodgers at Roosevelt Stadium in Jersey City, N.J., Kennedy enters the game as a pinch-runner.
In 1959, Elijah "Pumpsie" Green was the first Black player on the Boston Red Sox, the last Major League Baseball team to integrate.
After playing in the declining Negro Leagues, Kennedy signed with the Phillies in October 1956 and was invited to spring training in 1957. He received an endorsement from Phillies scout Bill Yancey, who compared Kennedy's swing to future Hall of Famer Ernie Banks's and predicted he would become one of baseball's better hitters.
