Every good hitter will do these 7 things on a perfect swing. Sometimes, depending on a pitch, not all 7 will be attained every time. It’s important to remember that hitting is a battle, and sometimes using your athletic ability to hit a ball will trump all the perfect mechanics we will talk about.
This doesn’t always mean a stiff leg, you can have a slight bend but this leg is keeping the rest of your body and hands behind the baseball. This leg will stop your forward momentum and start the axis of rotation that you will now be hitting on. This is very important, you lose this firm front side you lose a lot of bat speed and your head movement drastically increases.
When you commit your backside and decide to swing, the force you generate going toward the baseball will be abruptly stopped by your firm front side so you can start rotation, what’s left is your back toe on or slightly off the ground.
On a right handed hitter if you took the bat away at contact and had him open up his hands his right hand should be facing straight up towards the sky (or receiving the money) and the left hand should be facing the ground. This bat grip is the most powerful position you can be in at contact.
Seeing the ball at its contact point. This might be obvious, but it’s not simple. Knowing how to hit a baseball starts with knowing how see the ball.
A thought is to stick a pole in the ground through your knee, hip and head and rotate around that pole. That ensures you are not too far forward losing power and not too far bat getting tied up and having an uphill inconsistent swing.
Think of it as a triangle draw 3 lines between your head and two feet. A triangle is a very strong structural object used in many applications (roof joists etc.) So being in a strong triangle will be the strongest possible position for your body. Also it allows you to rotate on an axis with minimal head movement.
Ideally you want your elbow planted firmly against your side. This is where you are most powerful. The closer your elbow is to your body, the more torque you can create as you spin. The farther your elbow gets as you straighten it, the more you are losing power and leverage and making the force of the baseball more powerful against you.
