Are All MLB Teams Wearing #21 Today?

Major League Baseball (MLB) players don their uniforms with pride and passion, but this season, all teams are wearing the same number: #21. The league has decided to honor the late Roberto Clemente, an iconic figure in baseball and a beloved figure in the Pittsburgh Pirates organization.

What is Roberto Clemente Day?

Roberto Clemente Day is a celebration of the life and legacy of Clemente, who played for the Pirates from 1955 to 1972. He was a 15-time All-Star, won the National League MVP award in 1966, and was inducted into the Baseball Hall of Fame in 1973. He was also a humanitarian and a civil rights activist, and he was the first Latin American and Caribbean player to be inducted into the Hall of Fame.

In 2002, MLB created Roberto Clemente Day to celebrate his life and legacy. The day is held on the anniversary of Clemente’s death, which was December 31, 1972. Every year, teams wear his signature number (21) on their jerseys and caps to commemorate Clemente and his impact on baseball and the world.

Why is everyone wearing 21?

In 2020, MLB decided to make Clemente’s number mandatory for all teams. This was done in part to honor Clemente’s legacy and to bring attention to social justice issues that still persist in the United States. The league also wanted to acknowledge the current racial and social inequalities that many people still face.
