All Puerto Rican players in Major League Baseball will once again be allowed to wear No. 21 to honor Roberto Clemente on Sept. 15.

MLB has extended the honor to all uniformed personnel of Puerto Rican descent this year for the 20th annual Roberto Clemente Day.

In addition, all 2021 Roberto Clemente Award nominees, as well as the six active players who are Roberto Clemente Award recipients, can also wear the No. 21, according to sources.

During the pandemic-shortened 2020 season, when teams played in empty ballparks, MLB allowed all Puerto Rican players to wear the No. 21 to honor the late Pittsburgh Pirates star for the first time, after the Clemente family authorized its use.

It also was the first time the Pirates, the team for which Clemente played his entire Hall of Fame career, honored the life and legacy of "The Great One," with every member of the team wearing No. 21 on their uniforms.

This year, it will also be possible for any player, regardless of heritage or place of birth, to request to wear No. 21, as long as the club is given enough notice to create the uniform.
