How to Throw a Slider?
GamesHow to throw a slider ? A slider is gripped like a two-seam fastball but held slightly off-center. When thrown, try to manipulate the pitch to come off the thumb side of your index finger. Do not permit the two-finger release (used in the two-seam fastball) as it will cause the pitch to balance out, reducing the spin.

Summary
The slider is a pitch that can present a range of movement profiles but will mainly display an element of glove side sweep and a noticeable drop relative to the FB. A mastered slider can be a weapon for any pitcher. Understanding why this pitch type moves and how to throw it can provide the momentum you need to create one for yourself.
What is the method to throw a slider?
The Slider grip
Let’s take a closer look at how to grip and throw the slider.
A slider is gripped like a two-seam fastball but held slightly off-center.
When thrown, try to manipulate the pitch to come off the thumb side of your index finger. Do not permit the two-finger release (used in the two-seam fastball) as it will cause the pitch to balance out, reducing the spin. Your goal is the opposite - to activate spin.
Most good slider pitchers grip the outer-third of the baseball and lean their wrist slightly (not stiffly) to their throwing hand’s thumb-side upon release of the pitch. This enables a pitcher to apply pressure to the outer half of the ball with the index finger.
Avoid any twisting of the wrist upon release.
Place the long seam of the baseball in between the index finger and the finger that is in the middle of hand. Place the thumb on the opposite seam underneath the baseball (as shown in the first picture).
Some pitchers find it helpful to place their index fingers along the ball’s seam. The key with the slider is to hold the ball slightly off-center, on the outer third of the baseball.
Remember to slightly lean your wrist, but don’t stiffen it for a good wrist snap upon release. If your wrist is slightly leaned to the throwing hand’s thumb side, your wrist snap will enable the pitch to come off of the thumb-side of your index finger. This action creates a good spin on the ball.
The movement on this pitch originates from the baseball spinning off the index finger from the outside of the ball, NOT from twisting your hand underneath the ball.
Slider arm speed should remain the same as fastball arm speed.

Gripping the Ball
Throw a Slider Step 1:
1- Place your index and middle fingers. Grip the baseball with your index and middle fingers placed tightly together across an outer seam of the ball located at the horseshoe or U-shape seam. For right-handers, put your finger that is in the middle of hand across the right half of the seam. Left-handers should do the opposite: place your finger that is in the middle of hand across the left half of the seam. This should position your fingers towards the outside of the ball (off-center).
2- Place your thumb. Place your thumb under the opposite inside seam of the ball. The further your thumb is from your other two fingers, the more the pitch will drop. The closer your thumb is to your other two fingers, the more it will slide. If your index and middle fingers are at a 10 or 11 o’clock position, your thumb should be at a 4 or 5 o’clock position.
3- Put pressure on your index finger. Hold the pitch so that the most pressure comes from the thumb-side of your index finger.[1] The key to gripping a slider is holding the outer third of the ball.
Putting pressure on your index and middle fingers will cause the pitch to balance out or become a cutter.
4- Lean your wrist slightly to the thumb side of the throwing hand. Most pitchers do this to ensure that the ball releases on the thumb-side of your index finger. The movement of this pitch comes from the ball spinning off your fingers.
Avoid twisting your wrist. Bending your wrist can cause injury over time.
Throwing a Slider part 2:
1- Hide your grip:
2- Wind up and throw:
3- Keep your wrist loose as you release the ball:
Try not to drive your wrist forward with more than an adequate amount of force.
4- Snap your wrist when releasing a slider:
5- Think fastball as you release the pitch:
6- Aim for the slider to break on the inside or outside of the plate:
A left-handed pitcher’s slider should break down and away from left-handed hitters and down and in on right-handed hitters.
A right-handed pitcher’s slider should break down and away from right-handed hitters and down and in on left-handed hitters.
Frequently asked questions
Here are some frequently asked questions regarding How to throw a slider?
Q1: How do you throw a good slider?
A slider is gripped like a two-seam fastball but held slightly off-center. When thrown, try to manipulate the pitch to come off the thumb side of your index finger. Do not permit the two-finger release (used in the two-seam fastball) as it will cause the pitch to balance out, reducing the spin.
Q2: Why is a slider so hard to hit?
Outside of the science of our eyes, so much of what makes a slider hard to hit, according to Phillips, derives from the increasing velocity of the average fastball. For a pitcher like Jordan Hicks, whose average fastball sits at 101 mph, a slider can be a devastating complementary pitch.
Q3: Does a slider hurt your arm?
“Kids who threw the slider were at three times the risk of getting injured,” Register-Mihalik says. They reported more pain more often than other pitchers. One reason could be the mechanics necessary to throw a good slider. It requires a more violent arm motion; it’s like a combination of a curve and a fastball.
Q4: What movement does a slider have?
A slider is thrown with a regular arm motion, just like a fastball, and, ideally, the slider’s velocity is only slightly lower than the pitcher’s fastball. Thus, an effective slider can initially look like a fastball to the hitter. Slider movement is a direct result of the fingertip pressure and grip.
Q5: Why do sliders hang?
A slider that doesn’t break as much as a pitcher hopes are referred to as a “hanging slider” or a “hanger” and are much easier for the batter to hit because of its straight trajectory and sub-fastball velocity.
Q6: What makes a pitcher unhittable?
By its very definition, an unhittable pitch continually confounds hitters—even when they know it’s coming. That ability to make a hitter constantly swing and miss and shake their heads as they walk back to the dugout helps set that pitcher apart.
Q7: What’s the difference between a slider and a sinker?
What’s the difference between a sinker and a slider? A sinker is a fastball variation with slight arm side movement–called “run”–and sinking action. A slider is a breaking pitch in baseball that moves toward the pitcher’s glove side of the plate with a diagonal break.
Q8: Who threw the first slider?
So who threw the first great slider? Red Ruffing and Johnny Allen, big stars in the 1930s, are real possibilities, and Feller also is a candidate. With most of the great pitchers drafted into the Army or Navy during World War II (Feller enlisted), there weren’t a lot of great pitches thrown during those years.
Q9: How do you identify a slider?
Slider - This is slower than a fastball but with a similar release, Small to Med break. The best will break sharply, and late, they will have a drop and a slide to them. Hanging sliders will look like a slower fastball with very little and often early to mid-break.
Q10: Which is worse for your arm, slider or curveball?
It requires a more violent arm motion; it’s like a combination of a curve and a fastball. “And that means it’s a more risky pitch than a curveball, especially for kids at a young age when their muscles and bones are not fully developed,” Register-Mihalik says.
Conclusion
The slider is the next-fastest pitch to the fastball, and it relies on a tight spin that mimics the fastball, plus a pronounced late breakdown and away (in a righty vs. righty match up). The grip has the first two fingers close together and off-center positioned down the length of a seam.
On release, the pitcher uses the contact along the length of the seam and pulls downward to create spin. The slider uses the leverage of the seam, rather than a wrist action, to impart spin; try to do both simultaneously, and you’re headed for arm problems.
The spin is not straight through the ball, but off-center, due to the grip, and that spin pattern eventually causes the ball to “snap off” at a downward angle as it approaches the plate. The speed is below that of the fastball, but the closer a pitcher can get to throwing it at fastball speed, the better.
