The number "42" was what every player, coach and manager in the Major Leagues was wearing on April 15th. On that date in 1947, Jackie Robinson - who wore number 42 - became the first Black player in modern Major League Baseball history when he took the field with the Brooklyn Dodgers. Every year on April 15th, that historic moment is observed. Alex Rodriguez (l) - wearing his socks like Robinson did - Yankee captain Derek Jeter (center) and Robinson Cano (r) listen to the national anthem before their game with the Angels. Cano, who was named after Robinson, hit two homers in a Yankee victory. Jackie Robinson's window, Rachel, his daughter, Sharon and his grandson, Jesse, were on hand in New York for the special night that honored a baseball and civil rights giant.
