I'd like to be able to throw a curveball.  Do you have any tips?

The easiest way to “throw” a curveball is with a wrist motion that deviates a bit from a straight line.  You can also try to fling the ball with some backspin.  To do this, you have to shift your forearm to a more vertical angle as you release the ball, so that your hand has less control of its trajectory.

It can, but you can also use a device to help with this motion.  If you feel like you’re going to get frustrated, then it may be best to just practice throwing the regular pitch until you can get a feel for it, and then try to hit the curveball.
