How to Throw a Slider
As the ball approaches the plate, a slider seems like a fastball but suddenly trails off to one side, baffling hitters and making them slide right back into the dugout. Follow these steps to master throwing the slider.

1
Grip the baseball with your index and middle fingers across the seams at its widest point. Keep both fingers slightly toward the outside of the ball (off-center).
-
2
Place your thumb under the ball and keep the ring finger and pinkie off to the side. These two fingers should not make any real contact with the ball's surface.

3
Exert pressure on the ball with your thumb and middle finger.

4
Go into your windup. Remember to pivot and shift your body weight from the back foot forward toward home plate.

5
Keep your wrist loose as you release the ball, and try not to drive it forward with more than an adequate amount of force.

Throw the slider like a fastball, but 'cut' through the ball with the middle finger. Keep your fingers on the top of the ball until the actual release. Try not to twist your wrist; instead, turn the ball with your fingers. The greater the angle created by turning the fingers, the wider the break on the slider.

Follow through. Your feet should be parallel at the end of the pitch, and your throwing arm should come across the front of your body.

Note that the pitch should break late in its flight in the opposite direction from a curve ball. A left-handed pitcher's slider should break down and away from left-handed hitters, and down and in on right-handed hitters - vice versa for right-handed pitchers.

I'm sorry but i have to correct you on this: "cut down through the ball with your middle finger". that is really a bad idea, not to be mean or anything. that will cancel out the break in the pitch that should make it a slider. It will just flatten out the pitch. If you want a good slider, or an effective one, you need to cut through the ball with your INDEX finger, preferably with the side of your index finger that is closest to your thumb, which will make for a lot more "sliding". you should throw it as if you are throwing a fastball, or else it will really hurt your arm. if you throw it like a curveball, you most likely will need to throw it with less speed, which is unnecessary. Not to be mean, but it just made me sad that you were advising people to throw it like that. I made this same mistake and permanently blew out my arm. I was throwing 60 miles per hour in fourth grade, and...

When I throw sliders, I kinda throw it sidearm. When throwing, throw softly, but not to soft that it won't cross the plate. Believe me, my slider works. I've struck out 48 batters with my slider.
