From the back of the card: "During the off-season he acts in Hollywood movies."
Johnny Berardino's acting name was John Beradino, notice the slight change in his last name. And while he had a part in seven Major League seasons, he missed three season to World War II and won a World Series with Cleveland in 1948, he is best known or his work on the television screen.
From 1963 until his death in 1996, Berardino played Dr. Steve Hardy on "General Hospital." Yep, it's the same guy.
He even has a star on the Hollywood Walk of Fame. Not bad for life after baseball.
