Players to Wear No. 42 on Jackie Robinson Day

For the sixth consecutive year, major league baseball will honor Jackie Robinson with "Jackie Robinson Day." All players will wear No. 42 in honor of Robinson's entrance into major league baseball, effectively breaking down the color barrier that barred African-American players from participating.

Robinson's number 42 has been retired since 1997, 50 years after Robinson's debut. Players that were wearing 42 in 1997 were allowed to wear it until they retired, and Mariano Rivera of the Yankees was the last man to wear the number.

Jackie Robinson Day is just one of the many great things that baseball does to pay homage to its history. And its history exists in large part because of Jackie Robinson.
