Question: Which Cincinnati Reds outfielder began the tradition of wearing No. 42 on Jackie Robinson Day?

Answer: Ken Griffey Jr. Jackie Robinson Day is observed each year on April 15 across Major League Baseball. In 2007, Griffey asked Commissioner Bud Selig for permission to wear No. 42, which MLB had retired leaguewide in 1997, to honor Robinson. After Selig received Rachel Robinson’s approval, the league extended the opportunity to every player.
