On Jackie Robinson Day, Philadelphia acknowledged its racist treatment of the baseball pioneer when he played in the city nearly 70 years ago. City leaders issued an official apology in March, and highlighted its official apology during a ceremony Friday, also honoring Moses Fleetwood Walker, the first black Major League player.
