How do you throw your cutter?

and how is it supposed to spin?

a cutter is just a fastball thrown with your wrist supinated. the ball is supposed to spin with a rotation close to a bullet. if you look at some slow motion of rivera you’ll get it.you have to throw pretty hard and have a ton of rotation to it for the pitch to be effective. at least in the 80’s otherwise it wont do nothing or you’re throwing a slider/curve

i’ve got 2 ways i throw it, im figuring out what i liek more:

  1. Grip the ball like a four-seam fastball, put your index and middle finger together, and rotate them clockwise 45 degrees(1/8th turn) Then when you throw it, put pressure with your middle finger.

2)The seconf way is to grip the ball like a two-seamer, then take your finegrs and press them together, along the right seam. When you throw it, put pressure with your middle finger.

Both of these ways work, but use whatever works best.
