MLB chose to celebrate Jackie Robinson Day on April 15 to mark the anniversary of his first game with the Dodgers. Robinson officially broke the color barrier April 15, 1947. On that date, Robinson started at first base and hit second in a 5-3 win over the Boston Braves. Robinson went 0-for-3 with a sacrifice bunt in his first game in the majors.

MLB officially retired Robinson's No. 42 jersey across the sport in 1997 to celebrate the 50th anniversary of his big league debut. Griffey was given permission to don the number for the Seattle Mariners, flipping from his usual No. 24, for a game against Cleveland on April 15, 1997.
