Good morning, Athletics Nation! And Happy Roberto Clemente Day!
Today is September 9, which marks the annual celebration of Clemente’s life and legacy. The tradition began in 2002, when the Pittsburgh Pirates honored their old star on this day by all wearing his retired jersey No. 21, similar to how all teams now do for Jackie Robinson’s 42 once per season. The idea caught on, and the league began officially observing Clemente Day as an official event.
For anyone not familiar with Clemente, the Baseball Hall of Fame has a nice summary to start with.
