The curveball is one of the most famous throws in baseball. A baseball is thrown in such a way that it dives downward as it approaches the plate. The basic difference between the different types of curveball (basic, index-up, and knuckle curve) is in the grip and speed of the ball.
How to Throw a Basic Curved Ball
1. Use afour-seam grip.
Hold the ball so that two stitches are visible at the front and two stitches are visible at the back. For most pitchers, the four-seam grip is more effective for throwing curveballs than thetwo-seam grip. This grip allows the pitcher to throw the ball from any angle, as long as the hands grip behind the ball and throw it in a flicking motion.
A two-stitched handle is used to quickly throw the ball. The ball thrown with this grip turns left or right, while in curveball the ball must dive down.
2. Raise your middle and index fingers as if to make a peace sign.
Place the ball in the palm of your hand and flex your index and middle fingers so that they grip the top of the ball. Bend your ring finger so that the ball rests on its side.
3. Position your thumb and middle finger.
Place your middle finger along the middle seam (on the little side) and thumb on the seam towards the back of the ball.
4. Separate the tips of the thumb and ring fingers.
now the thumb should be at the base of the ball as opposed to the middle finger, with these two fingers resembling the letter “C” around the ball.
-Your grip should be firm but not too strong. Your thumb should still be able to wag behind the ball when it’s thrown.
– Don’t strangle the ball. Make sure there is some space between your thumb and forefinger, and a small space between your thumb and ring finger.
5. Throw the ball by snapping your thumb and middle finger.
When throwing a curveball, extend the back of the wrist. When releasing the ball, “flick” your thumb and middle finger together while flicking your wrist. At this time, your middle finger rotates down and your thumb rotates up to create aforce to centripetalcause the (twisting)ball to spin toward the plate.

– Experiment by slightly changing the grip depth and the position of the fingers (thumb and middle finger). Find a ball grip that is comfortable and matches your throwing style.
How to Throw a Curved Ball Up
1. Use a modified four-seam grip.
Thethrow is index up grip similar to the basic curveball, with the exception that the index finger remains relaxed and pointed upwards. This grip is suitable for beginners because the index finger can help direct the ball towards the target.
-Use this throw to practice your throwing technique curveball, but don’t use it in a match. Experienced hitters will be able to see the raised forefinger and predict where the ball was thrown.
2. Raise your middle and index fingers.
Bend your middle finger, and let your index finger lift upwards. Place the ball in your palm and rest the base of the ball against the side of your ring finger.
3. Position the middle finger and thumb.
Place your thumb behind the ball so it is along the bottom seam. Position your middle finger along the top seam opposite your thumb. At this point your thumb and middle finger should form a “C” while your index finger is facing up.
4. Get ready to throw the ball.
The index finger remains elevated and relaxed, while the ball is firmly grasped by the thumb (base of the ball) and middle finger (top of the ball). The grip should be firm, but the wrist and forearm relaxed.
5. Throw by snapping the thumb and middle finger together.
When throwing, the thumb rotates up and the middle finger rotates down. Use your index finger to control the direction of the ball. The ball will be thrown in the direction pointed by the index finger.
- The index finger is not needed to throw the ball, all the ball twist is produced by the thumb and middle finger.
- When throwing, your elbows should be at or above your shoulders. Your hands and wrists should form a straight vertical line with your forearms.
- Keep the forearm and wrist muscles relaxed until just before throwing the ball. Firmly contract and flick your wrist quickly forward and inward, so that the ball rolls over your middle finger.
How to Throw a Curved Ball Advanced
1. Use thefour-stitching grip.
In this throw, the ball is grasped with the thumb, middle finger and knuckle of the index finger. This grip makes the ball dive deeper and longer (closer to the bat). This throw is more difficult to make, but the knuckle curves increase speed without sacrificing ball spin.
- The average speed of the knucklecurve is 4 km/h, faster than a curveball regular.
- More than a quarter of the curveballs threw pitchers MLBin 2013 were knucklecurves.
2. Make a “peace” sign with your middle and index fingers.
Place the ball in your palms so that the seam bends to the sides of the ball. Bend your middle finger on the top of the ball so that it is along the seam. Then, slightly bend your index finger so that the knuckle is on top of the ball right next to your middle finger.
-Assume your middle knuckle is “digging” into the top of the ball.
3. Position your thumb and middle finger.
Place your thumb and middle fingers in the same way as curveball any other. Your thumb should be along the seam at the bottom of the ball so that it joins your middle finger to form a “C” shape. Secure the bottom of the ball by bending your ring finger and resting the ball on the first and second joints.
4. Use your knuckle as a pivot point to throw the ball.
Throw the ball like throwing a curveball regular. When the ball is released, snap the middle finger and thumb together so that it pivots against the knuckle of the index finger. This will help generate the speed and spin required for the ball to reach its target and break or curve downwards.
- Do throws far beyond the mound for a few minutes, increasing the speed of the throw gradually. This is a great warm-up and helps you relax before you get on the mound.
- Long throws off the mound for a few minutes, gradually increasing the speed with each throw, are a good warm-up.
- Don’t strangle the ball too much as this will reduce rotation.
- ball will not dive sharply when it reaches the plate. curveball A gooddives no more than 25 centimeters from pitcher to plate, but still enters thezone. strike hitter’s
- When throwing a curveball, the middle finger should always be in the lead.
- Begin standard grip exercises or index-ups before moving on to the knucklecurve.
- The farther the distance from the ball, the sharper the dive.
- The fingernails on the throwing hand are kept short and groomed. Long, uneven nails will affect your grip on the ball.
- Strengthen fingernails with clear nail polish, or nail polish.
- Stretch and warm up before throwing a ball. Ask the trainer for directions on the correct stretching technique.
- pitchers are Beginneradvised not to throw, especially curveballs, for more than 15 minutes to prevent injury and fatigue.
- following are movements that put additional stress on the wrist and arm when throwing a curveball: the hand and fingers roll under the ball when released, the pitcher snaps the hand and wrist straight down, the elbow is too low (below the shoulder) or dropped too far when throwing the ball, and the pitcher is still inexperienced or not warming up properly.
- Curveball should be avoided until the pitcher is past puberty to avoid the risk of serious injury. Curveball throwing should not be taught before entering high school.
- If you feel pain or stiffness in your elbows, wrists or fingers, stop the exercise immediately and rest. Consult a physical therapist or athlete’s doctor before resuming training.
