As Major League Baseball celebrates Roberto Clemente Day today, all Puerto Rican MLB players will be permitted to wear Roberto Clemente’s No. 21.

At the commemoration of the 19th annual Roberto Clemente Day, baseball players around the league will also be given the option to wear a “21” patch on their jerseys to commemorate the legacy of the late Pittsburgh Pirates star.

The Pirates have already announced that all their players and coaches will wear Clemente’s No. 21 on their jerseys for Wednesday’s game.

Clemente was the first Latin American player elected to the Baseball Hall of Fame and was a legendary figure for his achievements on and off the field. Among his achievements as a player: 15-time All-Star, 12-time Gold Glove winner, member of the 3,000-hit club, four-time batting champion and National League and World Series MVP.

Clemente was heavily involved in charity work in Latin American and Caribbean countries during baseball’s off-season. On New Year’s Eve 1972, Clemente died in a plane crash at the age of 38 while en route to deliver aid to earthquake victims in Nicaragua.
