Things You'll Need:

Step 1
The grip. You want the index and middle fingers of your pitching hand to be parallel to the seems on the baseball. The fingers should on the seams or inside the two seams. The ring and pinkie fingers should lightly touch the ball on the side in order to provide more stability. In order to create lateral movement on the pitch, you thumb should be slightly to the left at the 7 o'clock position on a clock (if you are throwing with your left hand, the thumb should be slightly to the right and at the 5 o'clock position) and on the smooth part of the baseball. The grip should not be too tight and there should be space between the ball and the palm of your hand.

Step 2
Throwing the ball. Throw the ball in your normal pitching motion. You snap your wrist down and to the left (the natural motion for a righty pitcher). The ball should roll off your index and middle fingers. It is important to keep your hand and fingers on top of the ball before it's released.

Step 3
Location. For the pitch to be thrown effectively, it must be thrown low. If it is thrown high (above the knees), it won't sink and be easy pitch for the batter to hit. The best spot to place a sinker in low and inside to a right-handed batter.

Step 4
Other notes. The closer your index and middle fingers are, the velocity will be lower, but there will be more movement. The further apart they are, the velocity will be greater, but there will not be as much movement. There are many variations to the grip on this pitch.
