why are the blue jays wearing number 21 today

The Toronto Blue Jays are wearing number 21 today in honor of Roberto Clemente Day, which is celebrated across Major League Baseball in September. Number 21 was Roberto Clemente's uniform number, and teams and players wear it to commemorate his legacy as a Hall of Famer, humanitarian, and baseball icon. This includes wearing No. 21 on their jerseys as a tribute as well as patches featuring number 21. The honor extends to players, coaches, and personnel, especially those of Puerto Rican heritage and nominees for the Roberto Clemente Award, which celebrates character and community contributions in baseball. Today, the Blue Jays and other teams wear No. 21 to celebrate Roberto Clemente's impact on and off the field, his 3,000 hits milestone, and his humanitarian legacy who died in 1972 while delivering earthquake relief supplies. This day is also part of the National Hispanic Heritage Month festivities in MLB.
