Sinker

Do you guys have any tips on developing a good sinker?. What i’ve started out with is gripping the ball in 2 seam position, but putting both fingers together on the right side (right hander). i put my middle finger in the seam itself and my index on the leather. I throw over the top if that helps.

Apply more pressure on the top of the ball and try to put as little as possible on the bottom which will give make it “sink” . Throw it with the same arm motion as a fastball. Also try to keep your thumb off the seams because it will effect the drop.
