3 fingered changeup

how do u throw a three fingered changeup
pleeez be very specific

put your middle finger on top of the ball and rip it wit your index andring fingers 3 quarters to halfway down he ball, make sure these fingers grip it tightly
put your thumb on the bottom of the ball, just don’t let your pinky touch the ball too heavilly
As you let it go you need to pull down on the ball like your scrapping your nails on a chalkboard. The ball should come out slower than a fastball and drop a few inches as it nears the plate
thats how I throw mine anyway

can u give teh grip for it

Its hard to explain, I’ll get some pictures up of my grip

actualy can anyone help me out on how to copy a pic on to a post?
