Get into a rhythm and hit the ball to all parts of the field to see where you hit with the most power. This will make you a better contact hitter. When hitting to the opposite field, use a finesse swing. Guide the ball where you want to hit it. This will help you keep your head down and your eyes on the ball as you make contact.
Batting is a stroke, much like a golf swing.
Hold the bat more in your fingers than in the palm of your hand and hold the bat loosely. This will increase bat speed. Remember that every human being is built differently. That is why players adopt different stances and make modifications throughout the years. When you find the posture and stance you feel enables you to swing through the ball at a maximum force with accuracy, remember the feel and positions of these points.
