Today is Roberto Clemente Day because Major League Baseball (MLB) established this day to honor the legacy of Roberto Clemente, a Hall of Famer and 15-time All-Star who tragically died in a plane crash on New Year's Eve 1972 while delivering supplies to earthquake victims in Nicaragua. The day commemorates his contributions to baseball and his humanitarian efforts. It also coincides with the start of Hispanic Heritage Month, recognizing his impact as a Puerto Rican and Latino icon. On this day, MLB recognizes players who exemplify sportsmanship and community involvement through the Roberto Clemente Award, and teams across the league honor his memory by giving back to their communities.
