Clark's high school coach used to watch the Ken Burns documentary "Baseball", prior to every season, and Clark has taken part since his sophomore year.
"It's exciting," Clark said. "I like that aspect of the game, learning about the players who played before. There was nothing pretty about it at all. It was all really personable. It was all about the players, not about what the fans thought, not about what the front office thought.
"Whatever you wanted to do, you did it. It was entertaining."
Clark's knowledge and desire to learn the history of the game may be rare, but it's far from the only thing that sets him apart.
