Question: does the bat boy travel with the team

Answer: No, During any given major league game, both the home and visiting team batboys will be drawn from the city where the game is taking place (batboys typically do not travel on the road with their team, unless they are relatives of a player). Home batboys often have regular jobs with a team, and thus may wear their first names on their uniforms; visiting teams, on the other hand, usually do not know who will be serving as their batboys on the road, and thus will send uniforms of various sizes to accommodate batboys of varying heights and weights.
