Mattingly compares Jason Collins to Jackie Robinson

LOS ANGELES -- Los Angeles Dodgers manager Don Mattingly said he believes NBA player Jason Collins' decision to announce that he is gay will have similar ramifications to Jackie Robinson breaking baseball's color barrier with the Dodgers 66 years ago.

Mattingly also said he thinks an openly gay player could be accepted in a major league clubhouse, saying, "I don't know why not."

"I think it'd be OK. It's the first time it's happened. It's just kind of uncharted waters," Mattingly said. "A lot like Jackie, he would make it easier for anyone else who would step forward."

Mattingly accompanied his players to a special screening of the movie "42," based on Robinson's story, this spring in Arizona.
