The Dodgers are wearing a "21" patch to honor Roberto Clemente as part of Major League Baseball's celebration of Roberto Clemente Day, which takes place on September 15 each year. The patch commemorates Clemente's legacy; he was a Hall of Famer who wore the number 21 throughout his career and was known for his outstanding achievements on and off the field. MLB players, managers, coaches, and umpires wear this patch as a tribute, and players of Puerto Rican heritage, past Roberto Clemente Award recipients, and current award nominees can also wear the number 21 as their uniform number during games on this day. The Dodgers, including players like Mookie Betts who is a Roberto Clemente Award nominee in 2024, wear the patch and sometimes the number 21 jersey in connection to these honors.
