The Pirates will wear Clemente's number 21

On September 9 the Pittsburgh Pirates will honor the memory of Roberto Clemente by wearing the number 21 on their jerseys.

The Puerto Rican baseball player disappeared in 1972 when he was flying to Nicaragua on a humanitarian mission.

Clemente was one of the best players of the time and in 1973 he was inducted into the Baseball Hall of Fame, being the first Latino to receive that honor.
