Roberto Clemente, #21
The #21 jersey worn by Roberto Clemente was retired by the Pirates in 1973. His jersey is one of just nine to be retired by the franchise.
I think it is time that major league baseball consider retiring #21 in the same way that they have honored Jackie Robinson’s #42. Clemente was the first hispanic player voted into the Hall of Fame and the first Latin player to win a World Series while starting for the team. And most importantly, he is known as being one of the most philanthropic athletes of all-time.
Major league baseball, you have my approval on this!
