why are yankees wearing 21 patch

The New York Yankees are wearing the "21" patch to honor Roberto Clemente, the legendary Puerto Rican Hall of Famer who wore number 21 throughout his career. This patch commemorates Clemente's life and contributions both on and off the baseball field. The "21" patch is worn by MLB players, coaches, and personnel to celebrate Clemente's legacy, especially around Roberto Clemente Day, which is recognized annually on September 15. Players who have won the Roberto Clemente Award are also given the option to wear this patch as a tribute. The patch symbolizes Clemente’s extraordinary character, community involvement, and impact on the game of baseball and society at large.
