In conjunction with Jackie Robinson Day, celebrated across Major League Baseball each April 15th, all players and uniformed staff wore nameless jerseys with Robinson's number. MLB retired No. 42 in 1997, making this the only day that anyone, besides Yankees closer Mariano Rivera, is able to wear the number. Rivera was wearing the number before the league-wide retirement.
"I think it's a great move by the game," manager Mike Matheny said. "What Jackie Robinson has meant to this game and what his memory stands for is something that we can't forget. The courage and the mental toughness that he had -- I think baseball picked the perfect person to come in and really break that barrier. He really represented himself and this game very well."
The Cardinals played a short video tribute with clips from Robinson's career prior to beginning their afternoon game against the Cubs.
