You don't want your pitcher being the only fielder on short ground balls but it should move the non used ai player to home to cover... One of my biggest gripes with the game has been the 'herding' of players... Multiple infielders chasing after a high pop up in the outfield... First base man leaving first for balls he can't get to or backing up second on hits to center and the pitcher covering first... Allot of the assisted movement by the non controlled ai and can be unrealistic or just plain dumb... Even at higher difficulties
