Instructions
Stand in a sideways stance in front of your television, just like you would if you were on a baseball diamond. Bend at the knees and keep your back straight.
Hold the Wii remote high and behind you to get a larger swing and more power. Hold the Wii remote lower and behind you to hit up and hit the ball higher. Using this method is the best way to ensure that the ball goes far into the field.
Swing the bat a little before the ball crosses the plate. You may need to practice a few times to get the timing down correctly. The game tells you if you are swinging too early or too late, and you can adjust your swing accordingly.
Aim straight and try to get full contact with the ball on your swing. Follow through with your swing to knock the ball into the outfield, or better yet, out of the park completely.
