This can make all your players Home-run hitters in a snap. If you didn't know already, you can adjust how you hit the ball. This trick will give you a higher percentage of home runs. First, look at your players pitches, and hold Z when your in your stance. While your holding Z, press the C button affiliated with the pitchers best pitch. While still holding Z, press the C button or one of the c buttons affiliated with your hot zone (if you don't have one, just guess low). Let go of the z button, then press B before the pitch, so just the yellow box appears (this is the "power box"). If your guessing is correct, the box will get really big, and if you make some contact with the upper part of the box, you will more than likely hit a home run!
