Josh Donaldson Swing | Before and After

Josh Donaldson's swing change allowed him to become one of the best hitters in baseball.

The mechanics that he implemented are not new. The great hitters over the last 100 years have all used these movements.

They are able to create early bat speed, get on plane and consistently square the baseball.

Early bat speed means that the initial movement of the barrel is towards the dugout behind him. If you watch closely, all of the great hitters have some kind of tipping action. This tip of the barrel is a loading action for the hands and arms to send the barrel back towards the dugout behind them.
