It’s hard not to see Clayton Kershaw’s curveballs like this all day as they drop effortlessly into the zone over and over again:
The curveball is unique in that it rotates from top to bottom, rather than bottom to top like the fastball.
This action results in it being thrown forward, in the direction of the fingers towards the batter.
On this particular pitch, hand speed transfers leverage to the front of the ball for that 12-6 motion that makes the curveball so effective.
The curveball is usually a strikeout pitch. it submerges when it reaches the plate. speed is just as effective as motion in creating deception and disrupting a hitter’s timing because it is generally much slower than a fastball.
So, what is the secret to a good curve?
let’s take a closer look at how to catch and throw the curveball…
- Grab a baseball and place your index finger on the ball.
- place your middle finger along the bottom seam of the baseball.
- place your thumb on the back seam.
- when throwing this pitch, the thumb should rotate up and the middle finger should rotate down.
- the arm action is shortened a bit at the end. bring the elbow of the throwing hand to the opposite hip, which will shorten your follow through, but allow you to get out of bounds.

Did you know? The curveball is unusual in that it spins from the top down, rather than the bottom up like the fastball. That’s because, instead of being thrown forward, in the direction of the fingers toward the batter, the curveball is thrown with the wrist bent so the thumb is up. with the arm lowered, the ball rolls over the outside of the index finger, causing a downward spin. the curve sags dramatically and can be thrown for a strike or as a “miss” pitch. depending on the position of the individual pitcher’s arm, directly over the top or more to the side, the ball could also go through the plate and end up outside. On this course, having the speed of your hand to transfer the lever to the front of the ball is more important than your arm strength.
