Every Pittsburgh Pirates player will wear No. 21 on Sept. 9 in recognition of Roberto Clemente Day, the club announced Wednesday.
Following the game, the jerseys will be auctioned off with all proceeds going to the Clemente Foundation and Pirates Charities.
"Since 1973 the only persons allowed to wear No. 21 in a Pirate uniform would had been any of the three sons. I became the closest to have that honor, but didn't continue to play to reach the Major League level," said Luis Clemente. "History will be made this September 9 and we would like to express our deepest gratitude to Derek Shelton for his initiative and supporting the Clemente Family endeavors.
