How To Cut A Baseball In Half

Improving an unintentional cut on a 4S fastball tin be particularly challenging. It's a habitual release blueprint of the ball with a cut and trying to change years and years of a specific motility pattern moving at high speeds requires dedication and piece of work. In this article, we are going to review many of the methods we've have used with some success when addressing excessive and inadvertent cut on a fastball.

However, this commodity does come with a disclaimer: We're not necessarily suggesting that y'all must fix a cutting on your 4S fastball. If a cutting fastball is an effective pitch for you lot, and you would similar to go along to throw your 4S fastball this way, yous should continue throwing it that manner. This article is meant for those who have a cutting and would like to accommodate their fastball to move like a regular 4S fastball with additional back spin and mayhap higher velocity.

What does a cut-fastball expect like out of the paw?

Past cutting fastball, we're not referring to a cutter pitch, which is thrown intentionally as a fastball with a much lower spin efficiency (35-45%) and an intended motion pattern unlike from a regular fastball.  This pitch is thrown with the intention of a 4S fastball, just as y'all tin come across from video the release is slightly off center and the ball has some degree of gyro spin.

Cut fastballs more often than not occur because the athlete's middle finger is besides far on the exterior of the ball, causing an increase in gyro degree and causing the alphabetize finger to generate a loftier portion of gyro spin.  Compared to a 4S fastball, the heart and pointer finger are positioned more in the middle of the baseball and go out the ball simultaneously resulting in more than pure backpsin.

What could be contributing to a unintentional cut-fastball?

Addiction – Y'all've been throwing information technology this manner your whole life and never really realized it, which is ofttimes why information technology'due south a difficult topic to address.

Recent Tommy John Surgery – Many of the pitchers that we run into with a cut-fastball are the guys in the gym who are actively recovering from Tommy John Surgery. Reconstructing the UCL generally results in a tightening of the pronator mass in the forearm. The inflammation in the pronator mass may result in the arm not beingness able to fully pronate and results in the supinated manus release found in nearly of these pitchers who cut their fastball. Generally, every bit their throwing programs progress into the catastrophe stages, the inflammation begins to dissipate, and the athlete returns to spinning the ball properly.

Mobility / Strength Issues – Mobility issues such as inefficient ranges of movement (ROM) tin can besides contribute to an inadvertent cut fastball:

• • Hip ER and/or IR
  • Shoulder ER and/or IR
  • T-spine Mobility
  • Insufficient Anterior Core Strength

These mobility problems combined with a lack of strength, especially in the younger athlete with less weight room experience, volition brand it hard for pitchers to hold on to, and maintain mechanical torque or tension in the throw.  This can cause a less than optimal throwing pattern and the inability to stay on the ball longer, which brings united states of america to the next topic, pitching mechanics.

Pitching Mechanics – Below are some of the mechanical bug we come across often that could likewise exist contributing to an inadvertent cutting-fastball:

Poor Horizontal Abduction (scap load) – Performing a good scap load helps resist early trunk rotation while maintaining a expert trunk stack into human foot plant. Information technology'south also a central thespian in producing expert hip/shoulder separation. We want to see the scap loaded back behind the trunk and the arm in a position to enter external rotation more efficiently (see Figure 8 Rocker drill further below).

Early Body Rotation – An athlete who is open with his chest earlier human foot plant may be pulling off as well aggressively with his chest thus causing his mitt to supinate in order to throw the ball towards his intended target (run across Marshall'due south below).

Slow Angular Velocity of the Hips, High Angular Velocity of the Body/Arm – An athlete with slow angular velocities in the hips, and college athwart velocities in the torso may result in the athlete aggressively rotating with his trunk. This would cause an altered extension and release indicate which may event in some cut.

Wide Glove Pull – A pitcher who is overly rotational with his glove-side may pull his chest and his throwing arm toward his glove side which may result in a cut fastball (run into Marshall's beneath).

Hooking the Ball – A pitcher who hooks his wrist in after hand break require more movement to and so straighten the wrist into release. If they take poor spin efficiency metrics, almost of the fourth dimension the movement of the wrist does non return to a spot with enough pronation to allow the ball to come out cleanly.

Poor Mail service-up – A bullpen with a poor post-up volition non take efficient stability in their lower half. Instability will and then travel up the kinetic chain and may nowadays weaknesses in the athlete'southward overall ability to control the residue of their body, specifically their throwing arm, into release (run into PVC Post-up drill farther beneath).

How to improve the inadvertent cut on the fastball?

Addressing a cut-fastball can be a process.  Generally, habitual motility patterns have ready in and it will crave a expert amount of dedication and hard work.  But it is definitely possible.  Withal, needless to say, there will exist process of trial and retrial until you begin to see results from i or some the post-obit alternatives.

The best way to instantly see if adjustments are yielding positive results is to utilize a pitch tracking software such as Rapsodo or Trackman. Cutting a fastball will be visible during take hold of play or during bullpens, but using Rapsodo will give you instant feedback on the extent of your cut.  Instant feedback will lead to a quicker ulimate set up.

Drill work – After mobility and strength issues have been addressed, we can farther assail any mechanical problems to a higher place with drill piece of work.

• • Marshalls into a High Armside Target – By placing the target off-centered towards the bullpen'south arm-side, we are forcing an external cue during the throw and making the athlete pronate more extensively into release.

• • Effigy 8 Rocker Drill (Scap load) – The Figure viii rocker drill helps to kicking the arm back into a more pronounced scap load past keeping the movement of the arm constant and using momentum effectively.

• • PVC Mail service-upwardly Drill (Poor Post Upwards) – The PVC post upward drill is meant to exaggerate the post up by giving an external block that the athlete is not meant to touch. Establishing the postal service up and improving stability in the forepart leg will lead to added stability through the rest of the kinetic chain in the commitment.

External Cues During a Bullpen

• • Off Centered Target – Some other approach would be to take your target or have your catcher move into the arm-side batter'southward box. By moving the intended target to a wider arm-side position, it will force the athlete to subtract the corporeality of supination in the throw and force more pronation. The pitcher will have to forcefulness the palm of his hand to exist more direct to a far inside target. Start the bullpen further out and progressively motility the target/catcher back to center. Nosotros still want the athlete to throw a bullpen to a normal target throughout his pen. Try to repeat the feeling of the beginning throws as the target moves more than toward the normal placement.

Catch Play – Let's get over a few tools and cues that we also employ to address a cut fastball.

• • Clean Fuego – The Make clean Fuego is a groovy tool for helping an athlete stay backside the baseball in order to spin the ball straight and to reduce cut.

• • Taped Baseball – You tin take some duct tape and wrap a line around the baseball game. This tape should be placed in between the fingers wherever the 4-seam fastball grip is held. Nosotros usually have our pitchers begin with the Make clean Fuego and so movement onto a taped or marked baseball, to increase their feel with an actual baseball.

• • Palm to Target – In order to reduce supination during the release, a cue we use often with our pitchers is to place their palm towards their intended target. This will increase pronation into the terminate and limit the amount of cutting on a pitch.

• • The Bernstein Method – The Bernstein method was created by one of our high schoolhouse pitchers during an attempt to prepare his spin efficiency. He tried putting his band finger next to his middle finger on his fastball grip. For him, having the extra finger on the ball prevented his desire to supinate during release. His spin efficiency metrics went from 60% to a consequent 95%.

You should progress and blend all of these drills from bones catch play to throwing off the mound.

Grip Changes – One simple change you lot tin can brand is with the grip on your pitches. Bullpen sessions are meant to work and experiment on different aspects of your delivery and your pitches.

• • Wider Grip vs Tight Grip – Change pressures on different fingers. A right-handed pitcher may want to put more pressure on his alphabetize finger to work with more pronation.

• • Change-up Feel – If the bullpen has a good changeup, then they are likely excelling with pronation for that pitch. I've had success with increasing fastball spin efficiency by simply telling our pitchers to throw their fastball like their changeup. Pronation increases, and the cutting on their fastball dissipates.

Final Resort

If all changes have been attempted, the final resort you lot can get to is request the pitcher if he would like to throw a cutter in place of his fastball. The pitcher is already placing his mitt in a position to throw a cutter, and so if we teach him a cutter grip, we may see some positive results with this pitch. This is a change that the bullpen must be completely comfortable with earlier making this adjustment, as it will completely change the style of pitching that he is used to.

Summary

For pitchers who have struggled with adjusting an inadvertant cut on their fastball, beware that information technology takes commitment and hard work and extended amount of time to correct. The first step is to recognize what function of your commitment may be causing it and so making the necessary adjustments to accost the issue. Every bullpen is different, then how y'all get nigh fixing this specific issue will likely be different for each athlete.
