Pitching Mechanics: The Leg Lift (RHP)

Having good leg lift mechanics is important to the success of any pitcher. The RHP must quicken up and reduce the height of his lead leg lift. A good technique to use is to bring the lead knee back to the pivot leg thigh area which transfers the body weight over the pivot leg. A little leg lift is necessary to allow time for the pitching arm to make its normal arm swing to the cocked position, and to transfer some body weight and momentum back before starting the body forward. 
The hands should break down along the mid-line of the body between the letters and the belt. The actin of the pitching arm should be down back and up, exactly the same as in the wind up. The RHP may want to break the hands on the first downward movement. 

The LHP may use a lot more preliminary hand action of up and down to hold and deceive the runner (runner on first only), but the RHP must break quickly to get the hand up into a good cocked position and unload the ball quickly. 

After the hand break, the pitcher’s motion and arm action should be the same as from the wind-up.
