Except in very rare circumstances, bat boys don't travel on road trips. Home and visiting bat boys are both employed by the home team. When a team goes on the road, they pack a bat boy equipment bag to take along, which holds uniforms for each of the teams they'll be visiting on that road trip. Since road teams don't know the size of the visiting bat boy assigned to it the team has to bring along a variety of sizes.
