Make sure that you go into edit rosters NOT the game settings sliders. You have to edit each guy on any team (I used the Yankees) and make their hitting stats 100%. Max out a pitcher while you are in here too. Only focus on the MLB guys and ignore the AAA and the other minor league guys. Then, choose an opposing team and lower all their stats. Classic controls do work best too. Play the game and you should be able to get 4 out of 5 achievements this way.
