"It's really a special day for me," Choice said. "Once they started doing Jackie Robinson Day, I always thought it would be cool to experience wearing that uniform in a big league park."
Robinson's number was retired all through baseball in 1997 and the first Jackie Robinson Day was held in 2007. April 15 marks the anniversary of Robinson's first game with the Brooklyn Dodgers in 1947 and the breaking of baseball's color barrier.
"I think it's awesome," Choice said. "He did so much for the game and opened up so many opportunities. It's truly incredible what he did. So to me it's an honor to wear his jersey today."
Choice is well aware of who Robinson is and the details of his Hall of Fame career.
"I know he played at UCLA and was in the military," Choice said. "I know he played Minor League baseball in Montreal and he played for the Brooklyn Dodgers in 1947. That was the same year my dad was born so it has extra special meaning for me."
Jackie Robinson Day has special meaning for many people.
"It's a great day," first baseman Prince Fielder said. "Obviously Jackie is the main reason why I'm able to play the game today. It's definitely a great day and it's definitely cool to wear No. 42 for one day a year."
