A slider is a breaking pitch that is thrown faster and generally with less overall movement than a curveball. It breaks sharply and at a greater velocity than most other breaking pitches. The slider and the curveball are sometimes confused because they generally have the same purpose — to deceive the hitter with spin and movement away from a pitcher's arm-side. (When a pitch seems to toe the line between the two, it is referred to in slang as a "slurve.")
Zito grips the ball with his index and middle fingers straddling the seam. "I want to get on top of the ball," he says. "When I release it, I force those two fingers down hard. That creates the torque on the seams, which causes rotation and spin. I also don't want to get my arm angle too high because that will take away the ball's bite -- I want to maintain a three-quarter arm slot."
A slider is meant to be slightly more deceptive than a curveball because it is thrown harder and has spin that more closely resembles a fastball — although it doesn't create as much overall movement. Many power relief pitchers possess only a fastball and a slider in their arsenals — with one pitch setting up the other because of the late deception created by the slider.
Do you know a baseball pitcher or someone who coaches baseball? Given the popularity of baseball, there's probably a good chance you know someone who can help you learn to throw a great curveball. Find a pitcher or a coach and ask them to meet you at a local field to give you a few pointers for throwing a great curveball. Enjoy giving your throwing arm a good workout!
The slider is a cross between a fastball and a curveball. It’s harder than a curveball, but with less downward action. The slider has a smaller break with a tighter spin. Many times you can see a small dot in the baseball as it’s coming toward you. It’s important for pitchers, parents and coaches to learn a proper slider grip and to learn correct slider throwing technique to ensure and promote good arm health.
Baseball players place a tremendous amount of stress on their arms and the ligaments which control how the arms and shoulders move. By practicing pitching drills which focus on developing and loosening these muscles athletes will be taking a step to avoid costly injuries. By adding core work into the pitching drill athletes will further protect their bodies by building a strong base at the center of their body.
Does your son or daughter have slider spin when throwing a fastball? A common problem in youth baseball is not informing kids that slider spin on a fastball is not ideal for throw/pitch efficiency.  How can you identify if your son or daughter has slider spin on the ball in their throws? First thing is knowing what you are looking for when you’re playing catch in the backyard. If your son or daughter is a righthanded thrower, the first good indicator of slider spin is YOU may be catching the ball on the right side of your body consistently pulling the throws across your body.  A slider has a clockwise rotation and spins on an axis that faces to player indicated by the blue line in the gif below. When playing catch you will be able to identify slider spin by seeing a circle in the middle of the ball. For righty or lefty throwers a 4 seam fastball should have close to perfect vertical spin/12 o’clock to 6 o’clock spin. A  2-seam fastball’s axis, in comparison to a righty, points towards 11 o’clock.  For young kids slider spin when throwing a 4 seam fastball is not horrible for them but can become a bad habit to break. Plus we want to have the correct spin on the ball, especially as a pitcher. In this article, we will identify slider spin, what causes it, and how we can help eliminate it from 4 seams and 2 seam fastballs.

Throw the ball at half of regular speed to your partner when practicing. A really important part of throwing a curveball is ensuring that you get the direction of the spin correct and that you can repeat this at least 80% of the time. As such, throwing at half your regular speed is a good halfway point to get your action started but to minimize the variables you have to battle.[10]

For a right-handed pitcher, a curveball spins clockwise as it heads toward home plate, pushing through the air, and slowing by the force of friction caused by the resistance of the air. Because of the ball's spin, air will pass more quickly on one side than the other. In other words, the air will move with the spin of the ball on one side and against the spin of the ball on the other side.

Go through your regular wind-up routine, but stop when you get to the kick, holding at your balance point for three to five seconds. Have a friend, coach, or teammate make sure that your leg is waist-height or higher, or have a look in the mirror. If you have trouble holding the stance for five seconds, practice tightening up your abdominal muscles, bending the leg you're standing on and aligning the height of your hips and shoulders.
A great drill for working on curveball rotation is the snap drill. It can be done anywhere as long as you have a baseball. Take your curveball grip and snap your fingers, making the ball pop straight up from your hand. Really emphasize the pull-down your middle finger creates on the ball. As the ball rises out of your hand, you should see good vertical rotation and minimal horizontal rotation.
For this pitching drill you don’t necessarily need a net. You can use a wall or another person. But the idea is to have something behind the pitcher that will let the pitcher know if he has broken his hands too early or is not gaining enough ground going forward. This is a great pitching drill if done correctly and will promote torque as well as linear momentum. Check the vid for more of an explanation!
