There are several versions of the Slider, but we will illustrate the cut-fastball version (aka a “Cutter”) because it’s the easiest for most people to learn and throw. The Cutter is gripped similarly to a Two-Seam Fastball (index or middle finger along the Blitzball seam), except the two fingers should be closer together and the ball should be held with an off-center grip (towards the outside half of the ball).

The difficulty with this pitch isn't from the pitch itself. In fact, most pitchers feel this grip gives them the most rotation – and most movement – of any breaking pitch. However, many pitchers who are learning this pitch for the first time, aren't comfortable with the "tucking" part. It's not super comfortable at first to tuck your index finger into the baseball.
Next, place your middle finger along the bottom seam of the baseball and place your thumb on the back seam (as shown in the middle picture above). When this pitch is thrown, your thumb should rotate upward, and your middle finger should snap downward while your index finger points in the direction of your target. This, of course, is the reason this pitch is great for beginners: the ball goes where your index finger points. The beginners curveball helps to align your hand and ball to the target.
A well-timed curveball can be highly beneficial to pitchers, but a curveball is pretty useless if the batter knows it's coming so that he or she has time to adjust to the swing. For that reason, it's important that pitchers not only master the grip and motion of the curveball but also the secrecy of the grip itself, which is necessary for fooling the batter.
The slider breaks down about six inches and in by six inches to an opposite hand hitter. A left-handed pitcher’s slider breaks down and away from left-handed batters; down and in on right-handed batters. It appears to be a fastball but breaks at the last minute going about six to eight miles an hour slower than the fastball. It is one of the fastest pitches in baseball.
7. Parallel Feet Drill - Works on upper body mechanics. This drill isolates the upper body. The pitchers face each other chest to chest with the feet at shoulder width. The lower body remains stationary. The ball is held in the glove in the "check-your-pulse" position. The torso twists at a 90 degree angle as the ball is pulled down out of the glove, and in a sweeping arc brought to the power position with the hand always on top, and the elbow at least at shoulder level. The delivery is then made and the proper follow through is checked. The glove elbow finishes pointed toward the sky. The drill emphasizes that the pitcher throws with a "proud chest" that remains closed as long as possible.

A pitcher's should stride at a minimum 80% his height towards home plate during his fastball delivery. On the curveball and change-up, his stride should be six to eight inches less than his height. For example, if a pitcher is 5 feet, 10 inches tall, then his stride toward home plate on the release of the baseball should be 5 feet, 2 inches (or thereabouts).


Being able to identify if your son or daughter is trying to throw a 4 or 2 seam fastball and throwing a slider instead is also key. They are different spin axises that affect a consistent ball path. So when playing catch learn how to pay attention to spin on the baseball along with consistent movements. Ask your son or daughter what they are feeling on a throw to throw basis. What finger did the ball feel like it came off? Did you see the spin on the ball? Where was your eyesight? Your arm swing looked a little stiff, did you feel that?
Any baseball pitch begins with how the pitcher grips the ball. To throw a curveball, a pitcher must hold the baseball between his thumb and his index and middle fingers, with the middle finger resting on the baseball seam. When the pitcher comes through his motion to throw the ball, he snaps his wrist downward as he releases the ball, which gives the ball topspin. If the pitcher throws properly, the back of the his hand will be facing the batter at the end of the motion. The ball will break down and away from a right-handed batter if thrown by a right-handed pitcher.
Start with the hands together, ball in the glove. The legs are positioned in the exact same manner as the high-cock drill, toes of the lead leg facing the target. The legs remain in this permanent, shoulder-width-apart position throughout the drill. However, the back foot will pivot onto its toes when the ball is released (like when you pivot your back foot during a golf swing or baseball bat swing). However, the distance of the two feet remain the same.
