Q&A for How to Throw a Cut Fastball

Yes. Throwing a cutter will not torque your wrist or violently turn your thumb and fingers, both of which stress the tendons. A fastball/cutter is a clean throw. Your arm will last longer if you continue to pitch as you age.

No, this is just a pitch that curves inside or outside depending on what arm you throw with. Throwing this way will give you a tactical advantage but your speed will stay the same.

For the grip its just a regular curve ball, but you put your middle finger's knuckle against the ball. For the delivery, it's a fastball delivery, but experiment and figure out which is best for you.

It can take awhile to develop, but some people have a raw natural talent for it. Like anything, the more time you put into it, the better your results will be.

No, a slider is a different delivery. It is not the same arm swing.

Make sure as little as possible of your hand other than your fingers is on the ball.
