When do you do it?I tried to pronate a bit with the fastball grip and ended up with a slight slider movement (which was just downright cool) but i have no idea when to do it. Someone told me that the reason that i had elbow problems is because i probably supinate my release. I did.

How am i supposed to throw a curve ball which starts out in the supinated position? Basically i have no idea how to pronate a pitch.

Thx for your time

pronating just means turning your palm outward upon release.

yes… so i just prontate after the pitch?

if you are trowing to get some sort of tailing/sinking action then yes.

its not just pronation
its also how to release the ball

u probaly released it of the thumb side of you index finger
