The hardest thing when telling a young fan about the Dodgers' most recent World Series title is explaining why baseball used to be a game played by broadcasters.It was 1988, recall, and the team's star was Orel Hershiser, who today is best known as a local in-studio commentator.The defining moment came when Kirk Gibson, a color analyst for the Detroit Tigers, hit a home run off Dennis Eckerley, who does television for the Boston Red Sox.
