We’re on a mission to retire Roberto Clemente’s #21 across Major League Baseball.

Currently, only one number has been retired league-wide: Jackie Robinson’s #42. That honor is well deserved. But we believe Roberto Clemente should also receive the game’s highest recognition. His on-field accomplishments were legendary, and his humanitarian impact went far beyond baseball.

This effort began as a Change.org petition. While starting a petition is easy, sustaining momentum is not. We quickly realized this needed to be more than a petition—it had to be a movement.

That belief led to the creation of RETIRE 21. By building a brand people could rally behind, we aimed to inspire fans to help spread the message through conversation, community, and social sharing.

So the question became: how do we turn belief into action?
