ATLANTA — Wardrobe needed a catcher’s mitt. It was the fall of 1987. A former minor league infielder named Ron Shelton was filming a baseball movie at Durham Athletic Park that revolved around a journeyman catcher. Someone rooted around the manager’s office at DAP, the one that summer that belonged to Brian Snitker, manager of the Durham Bulls, the Triple-A affiliate of the Atlanta Braves. The wardrobe scout hit the jackpot: sitting there for the taking was the catcher’s mitt used for years by Snitker, a former catcher who had used the mitt as Braves bullpen catcher in 1985.
