The Ballboy Manager is the......well, guy who manages the Ballboys at the RFK Memorial Stadium in Baseball He (correctly) notices Chris is in his 30s, and asks him if he's a 'little old' to be a ball boy. Chris creates an excuse that he has a 'condition' and this seemingly satisfys him.

Aren't you a little old to be hanging around the stadium?

His appearance appears to be at least partially based off of Donald Trump.
