Major League Baseball celebrated Jackie Robinson Day on Wednesday with all players and on-field personnel wearing No. 42.
Thinking of all that Robinson had to endure to pave the way for African-Americans to play in the Major Leagues makes Cain never take for granted his position in the big leagues.
"I would say a few years into my career I started to realize what he did," Cain said. "Even when I went to the movie ['42'] it made me even more aware. I know that movie doesn't tell the whole story, but it's as close as we'll get to kind of picture all he had to go through -- the perseverance.
"He was strong. I can't imagine what he went through. I can't imagine anyone having to deal with what he had to deal with."
