Gripping a curveball is simple. Place your thumb on the bottom seam of the baseball and then place your middle finger directly above your thumb; splitting the baseball in half with thumb and middle finger. Your index finger is placed right next to your middle finger. Make sure your index finger applies no pressure on the ball. When you start throwing the curveball you can experiment how tight you want to grip the ball. If your grip is too tight the ball can “squirt” on you or it will not make it across the plate. If your grip it too loose you will lose complete control and the ball won’t even know where it will go. Thumb and middle fingers are the only two fingers that apply pressure on the baseball.
Snap the release. Keep your palm facing inward to your body, and release the ball as you step forward with the opposite foot. The ball should be out of your hand shortly after it passes your head. As your arm comes down from the throw, snap it toward the opposite hip. Twist your thumb upward and your middle finger downward to put a spin on the ball.[16]
Don't worry about wrist motion; keep your wrist firm and worry about the angle of your arm. This will maximize bottom-left break if you are a right-handed pitcher. The side of your hand should always face the batter, and your wrist should always finish at your left hip (again, right-handed). Also, try to aim at the left shoulder of a right handed batter, as this is a good aiming spot for the break to be efficient. For more information, you can refer to this article: How to Throw a Curveball.
This is a good partner drill to practice with a friend or teammate, as it will give you both an equal opportunity to practice improving your accuracy. Start by sitting cross-legged on the ground, facing each other, about 20 feet apart (gradually increase the distance to 30 feet as you get better). When you start, toss the ball back and forth, aiming at each other’s centers. The less the receiver has to move his arm to catch the ball, the more accurate the pitch.
First and foremost, when you take the mound, the main thing that you need to focus on, is executing pitches. Thus doing so consistently, means that the results position you above the rest of the pack.  Now who doesn’t want that? Whether you are new to throwing the Slider, or you need to go back to the drawing board, hence this post/video will simplify your process dramatically.  You will not be able to find this basic yet dynamic information anywhere.  Believe me, I have looked.  Of all the Game Changing content that the Slider Domination Blog has provided for pitchers, this is the most important one yet. Very easily, this is How to Throw a Slider in Just 3 Simple Steps.  Throw the Slider consistently, and you will flat out DOMINATE THE COMPETITION!!
Whether you're in the middle of a season, practicing in the off-season, or getting warmed up for another year, baseball pitching drills are an excellent way to perfect your technique, work on new pitches, and keep your muscles active and ready. But when you’re juggling school, hobbies, and other activities, you don’t always have time to hit the baseball diamond to practice on your own, and that’s when baseball pitching drills like these three can come in handy.
Your next indoor baseball practice is a great place to train your accuracy with a helpful and effective drill from the mound. To run this drill, you’ll need a catcher and an additional teammate to stand in the batter’s box. Your teammate should be carrying a bat and wearing a batting helmet, but they won’t be swinging at any pitches. Instead, they’re serving as a point of reference for your aim.
Athletes will begin the pitching drill by standing at one Speed and Agility Cone, raise their inside foot and balance on the outside foot (athlete lined up on left side raise right foot, balance on left foot). From this single leg position athletes will slightly bend the knee and explosively jump laterally toward the opposite Speed and Agility Cone. Athletes should try to keep a good body position by not allowing the hips, shoulders, or chest to rotate at any point during the jump or landing. Athletes should also not allow the chest to lean forward during the pitching drill. Athletes will land the jump on the opposite leg they jumped with, balancing on the landing leg while raising the opposite knee in a pitching motion. Athletes will then balance on their outside leg (same leg which they landed on) and explosively jumping back toward the original Speed and Agility Cone.
B) Twist or snap your wrist: In this brief pitching video I explain this myth in greater detail. If you twist your wrist right before release of the baseball you will experience elbow problems in the long run. In fact, you will know that it is wrong to throw the ball like this to begin with because your arm will tell you it’s wrong. Why do pitcher’s continue to throw like this? Again, this method works for some pitcher’s because it does impart rotation on the ball. The wrong rotation, but pitchers find success with it so they continue to use it.
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.

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.
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!
