I'm not sure I know what you mean or if this helps:
You have two loadouts you have created and added perks to on the loadout section of "my ballplayer." One is for your pitcher and a separate one for your hitter. Before the game it asks you which you want to activate and obviously it's always the hitter one unless you are pitching that game.
If you pick the wrong one it will dramatically affect your performance. For instance, if you are pitching with the hitting loadout activated you will be pitching with none of your loadout bonuses.
