Welcome to part 5 of ours “How come Throw” series: how to litter a Slider. In this segment, we space going to cover sliders, the breaking ball best known as one of the nastiest (and most valuable) pitches in baseball. We’ll analysis why sliders move so effectively and detail different grips that you deserve to experiment through on your own.

Overview the a Slider

A slider is a breaking ball that moves in countless different shapes and sizes, predominantly with gloves side action and 10-15 customs of drop off the FB. 

This activity is created because the ball will turn with a combination of next spin and gyro (or bullet) spin. Sliders are likewise usually thrown quicker than a curveball and are approximately 6 to 10 mph turn off the fastball.

As mentioned, there space a few different family members of sliders, any of which deserve to be efficient in a player’s arsenal if thrown v the right metrics. Since each SL form can it is in successful, it is specifically important to understand what type of motion your pitch has actually in order come decide how to boost upon it.

How come Grip a Slider

The most usual grip type among our athletes is referred to as “SL 2”. It is a standard grip that is held with the fingers slightly off-center in between the inside seams. The middle finger is placed straight on a seam, while the index finger is on the leather. Both fingers are vital at release to impart the essential spin the leads come a slider’s desired movement.


The ignorance is positioned for support on the opposite side of the ball and also just off-center. That position have the right to be adjusted based ~ above comfort. Compared to a curveball, the slider might not be tucked as deeply into the palm—although this varies in between athletes.

The knuckle of the ring finger is inserted on the next of the sphere in stimulate to help maintain control, when the pinky finger is fully off. After did you do it positioned her fingers comfortably, you should organize the sphere with a decent amount of pressure between your thumb, index and middle fingers.

How to throw a Slider

Throwing a slider is similar to throw a curveball, through a few minor differences. Take a look at the example Edgertronic footage below.


Notice just how the pitcher’s hand is slightly off to the side; this allows the finger to come around and also pull down on the next of the pitch to produce side turn or gyro turn and, ultimately, the desired lateral movement.

One the the cues us recommend is come “slash the zone” v the ball, or come “throw it prefer a football.” The pitch should feel together if the “slides” the end of the hand upon release.

Depending on her success, the pitch should relocate towards your gloves side and also appear come drop during the last couple of feet. If you nothing have access to high-speed video, you have the right to pay attention to the type of spin and movement the ball has actually during catch play or bullpens. It can take time to construct a feeling for this pitch, but further practicing and using various cues will help in your development.

Analyzing Slider Movement

If you’re all set to litter on a Rapsodo device, you can analyze her pitch’s movement profile utilizing the horizontal and vertical break plot. Note that the complying with graph represents right-handed pitchers and also that for left-handers the results would be the mirror image.


The H&V rest plot shows a spectrum of different sliders, which are highlighted in blue and also located to the left of the y-axis. Together shown, these pitches (from a RHP) display an unfavorable horizontal movement and also a minimal quantity of an adverse vertical movement.

As stated earlier, there space varying slider profiles. Referencing the break plot, a “frisbee slider” would loss further native the y-axis, if a “gyro slider” would fall closer come the centerpoint and also a “slutter” would certainly fall above the x-axis with a slight amount of horizontal movement. Lastly, a slurve would end up in between the blue and also yellow baseballs above.

We have to note that, while part slider varieties outperform others across a given sample (for example, frisbees have tendency to outperform slurves), every pitcher will find a grip and also SL kind that is best suited to their skills, arsenal, and also comfort level (not every slurve is worse than a frisbee).

This analysis should provide you an knowledge of the different varieties so the you can analyze them once you practice, and also ultimately decision what is most reliable for you.

Additional Grips and Cues

Below we have detailed additional grips and cues. You’ll notification five other slider grip types. Every grip will certainly vary in between either seam orientation or index finger usage.

The differences between SL 1, 2, 3 and 6 are seam position. While both the index and middle fingers are put onto the ball, their location differs. SL 1 is held similarly to a nearby four-seam fastball grip. The fingers room off-set come the side of the ball, through the finger pads positioned on the seams. 

SL 3 has the finger placed between the inside seams, yet unlike in SL 2, they room farther up and also closer to the horseshoe. SL 6 proceeds along that exact same path, and also in this case utilizes the bulk of the horseshoe. 

SL 4 and SL 5 share commonalities v grips 3 and 6 in for to placement on the ball, however the main differentiating factor is the use of the index finger. This kind of fixed starts to resemble a “spiked slider.” 

In those examples, by digging the pointer of the finger right into the round the pitch becomes “spiked.” The quantity of push imparted by the fingertip will certainly vary between athletes based upon comfort. Due to the fact that most that the work imparting turn is done by the center finger, you’ll typically see the positioned ~ above a seam, if the “spiked” index finger gets out of the way and enables the center finger to maximize its pressure onto the ball.

Additional cues: “Throw the back of the hand”, “Throw it like a football”, “Pull top top the side of the ball”, “Slash the region in fifty percent diagonally”

“Standard Offset” SL 1


“Standard Around” SL 3


“Standard Spike” SL 4


“Horseshoe Spike” SL 5


“Horseshoe Standard” SL 6



The slider is a pitch that can present a range of motion profiles, however will mainly display an aspect of gloves side sweep and also a noticeable amount the drop family member to the FB. A master slider have the right to be a weapon for any type of pitcher. Understanding why this pitch type moves and also how to litter it can carry out the inert you require to create one because that yourself!
