    • How To Throw Curveball
    • Six Tips For Throwing A Better Curveball

       

    • The mechanics of a curveball are NOT the same as a fastball. There are several key elements to the curveball that must be followed in order to throw the pitch properly:
    • Ideally the pitcher will find a grip where seam will provide resistance against that middle finger during the release. That is how the curveball gets its tight rotation.
    • The key finger in a curveball is the middle finger.
    • If you find that one of your pitchers is having difficulties getting on top of their curveball (pitch constantly coming out high), get them to shorten their stride by 2-4 inches.
    • The throwing elbow must be equal to or slightly above the throwing shoulder. As soon as the pitcher lowers the elbow below the shoulder, they put additional stress on that arm. The angle of the elbow joint should be no more than 90 degrees. Pitchers who throw curveballs at angles greater than 90 degrees may put additional stress on their throwing shoulder.
    • The path of the ball on a fastball is generally far from your head. In the case of a curveball, the path will be much closer to your head (slightly up and away from your ear).
    • A fastball release is straight out in front of your body.
    • When releasing a curveball, your wrist will be hooked and your hand will pull down in front of your body. It is important that you release the ball close to your body (Short Arm)
    • The further you release from your body, the less resistance your middle finger will have on the seam and therefore your rotation will be looser. Loose rotation curveballs tend to spin or hang.
    • It is extremely important that you maintain similar arm speed with your curveball that you have with your fastball. A hitter reads arm speed.
    • Another way to get a tight rotation and hard downward movement with a curveball is to throw it with quicker arm speed. If two pitchers have the exact same curveball grip, mechanics, release, etc. but one throws it with quicker arm speed, the one with quicker arm speed will throw the curveball with more break, and thus the harder pitch to hit.
    • “My dad and I picked it up out of a book when I was 7,” he says. “He caught me in the backyard…. Then I threw to a mattress with a painted strike zone on it.”
    • I also don’t want to get my arm angle too high because that will take away the ball’s bite — I want to maintain a three-quarter arm slot.”
    • Age to Teach the Curve Ball and How to Teach It

       + Common Faults That Add Stress on the Pitching Arm

    • How well developed are the biceps, triceps and forearm muscles?
       – A young pitcher needs arm muscle strength to help stabilize and control the forces on the elbow joint during the acceleration, release and deceleration phases.
      • Andy needs to be able to do 20 pushups
    • Most of the stress from throwing the curve ball is on the ligaments of the elbow, the biceps and forearm muscles. Since the hand and arm speed is slower than on the fastball and slider, and the elbow leads longer, there is usually not as much stress on the shoulder joint as on the fastball.
    • Most young pitchers’ hands and fingers are smaller and shorter, so the youngsters have problems gripping, controlling and releasing the pitch properly. This often causes the hand, wrist or elbow to be out of proper position during the acceleration and release phases, which can lead to injury.
    • The following is a curve ball drill sequence that I use to teach and re-enforce proper techniques to throw the curve ball. Notice the ball is thrown from short distances and slow speeds. The purpose is to teach the pitcher proper techniques and develop the proper feel of the pitch without creating stress on the throwing arm.
    • Grip: We teach a four (4) seam grip with the middle finger pressed up against a long seam.
    • Do not choke the ball so deep that the thumb cannot flick up behind the ball during the release phase.
    • The pressure points on the curve ball should be: the outside of the middle finger against the seam, the ball stabilized between the 1st and 2nd joint of the ring finger, and the inside of the thumb. The first finger is relaxed and up against the middle finger.
    • From the cocked position, rotate the trunk, and lob (spin) the curve down and away.
          Develop the feel, muscle memory, of the fingers coming down over the top outside of the ball (1 to 2 o’clock) and the thumb flicking up – through the back of the ball creating a fast over-spin.
          The wrist snaps forward and inward and the ball spins out over the middle finger.
    • Throw (lob) the ball from a 25-30 foot distance to learn the feel.
    • Via high speed video, we have observed that pitchers with outstanding curve balls:
          1. Have the hand high in the cocked position (elbow shoulder height) so they can throw in a downward plane.
          2. Get their trunk squared to the plate during the acceleration phase.
          3. Have a loose wrist that snaps downward and inward right after ball release.
          4. Bring the head and throwing shoulder down over and outside a braced stride leg more forcefully than on the fastball (forward torso flexion).
    • B.  Other common technique faults
          1.  Grips the ball too deep (“chokes the ball”), which reduces ball rotation. Also, the thumb is placed on the side of the ball versus under the ball.
          2.  Grips the ball too loosely. The ball slips out, reducing rotation and causes control problems.
          3.  Cups the wrist (inward flexion) during arm acceleration and the release phase, reducing pitch velocity.
          4.  Front side flies open early causing the throwing arm to drag and get too low.
          5.  Starts to flex forward before the trunk squares to the plate.
          6.  Not focusing on specific spots. Think “curve ball for a strike” or “curve ball for an out” (2 strikes on batter; start the pitch in the strike zone and break it down and away).
    • Note: When working on the curve ball at a normal distance and velocity, a pitcher should not throw over 5-6 curves in a row. The forearm flexor muscles tend to fatigue quickly. Throw one or two fastballs for arm muscle extension then go back to the curve.
    • he pitcher’s action up to the release of the ball is part of the art of pitching; the action of the ball after release … is addressed by physics.
        —Robert K. Adair, The Physics of Baseball, 1994
    • The Davis researchers say their system could become useful to coaches as a new tool for tracking their pitchers’ performances. Perhaps, but their work already has scored points in the long-standing debate about the role of baseball seams in curve balls.
    • The popular lore among players is that four-seam pitches curve more than two-seam pitches do.

        

      So far, scientists have been unable to confirm the players’ hypothesis.

    • A four-seam pitch makes the air around it more turbulent than a two-seam throw does, so it actually curves less, he surmises.
    • Wind-tunnel studies dating back to Lightfoot’s work in the late 1940s paint a confusing picture. Lightfoot, for one, found a striking difference between two- and four-seam orientations when he gauged the curve-inducing aerodynamic force known as lift. His measurements revealed that lift on four-seam pitches is up to three times as great as on two-seam pitches. But tests by other scientists since then have revealed no such difference.
    • In trials using high-speed photography and balls marked with reflective tape, Alaways and Hubbard collected data from pitches thrown by a pitching machine. From trajectory and spin data, Alaways’ software determined the release conditions, including the initial lift on the ball, for nine pitches thrown in the two-seam orientation and eight thrown in the four-seam orientation. The researchers also varied the conditions of spin and initial velocity to cover a range of possible pitches.
    • Without additional data, it had been difficult to come to a conclusion about the role of seams in curve balls. The newer results break the stalemate, Alaways says. Collectively, the data suggest that the distinction between 2- and 4-seam orientations diminishes as the speed at which the seams circulate begins to compare to the speed of the ball itself.
    • Adair also has come around to thinking that the four-seam ball probably curves more, a new perspective that he says will show up in the next edition of his book.
    • Their analysis of the videotaped trajectories produced hints of another aerodynamic effect called the drag crisis—a steep decrease in air resistance, or drag, on moving bodies above a certain velocity. If further studies confirm that there is a drag crisis within the ranges of speeds that pitchers can throw, then balls fired above a certain speed wouldn’t lose velocity as fast as balls thrown just a little slower.
    • In all seriousness, if the human body needs calories for perceived survival, as in flight-or-fight (running), we have many systems that can convert whatever we have on board to energy. Some forms of calories may work, or rather convert to energy, more easily than others but then again, the human body has adapted for thousands of years, day in and day out, in a struggle for continuous survival and a mere 100 miles has not been the ultimate challenge.
    • If you read Christopher McDougall’s book Born to Run, you may have read my definition of an ultramarathon, “An eating and drinking contest, with a little exercise and scenery thrown in.”
    • It’s important to realize that I’m not a professional athlete. Over the last two years, I have balanced a life of 20-30-hour training weeks and crazy endurance events with my career as an entertainment lawyer, my family life (married 10 years, father of four), and writing a book. Developing an acuity for sleep deprivation is a big part of my personal success equation.
    • Stamina. Well-known for centuries in Chinese herbal medicine, Cordyceps sinensis is a parasitic dried fungus that grows on caterpillar larvae native to high-altitude regions of China, Nepal and Tibet.
    • The benefits of Cordyceps are enhanced when combined with the adaptogen rhodiola, as they are in Optygen and ShroomTech — both good recommended products.
    • What you might not know is that turmeric — due in large part to curcumin, turmeric’s primary active ingredient — is one of the most powerful anti-oxidants and anti-inflammatories on the planet.
    • In the fitness context, exercise-induced physiological stress causes inflammation, which impedes muscular repair.
    • In a general sense, the more quickly the inflammation subsides, the more quickly one recovers from training. Foods
    • Curcumin can be taken in capsule form, but it is not the most bio-available substance in extract form. Personally, I prefer to drink turmeric in a tea — 1/2 spoonful dissolved in hot water does the trick
    • Similar to green tea and grape seed extract, organic raw (green) coffee beans have powerful anti-inflammatory and anti-oxidant properties effective in combating free radical damage
    • Suma Root & the 4 Ginseng Blend:
    • Moringa (Olefiera):
    • As a 100-mile ultramarathon runner, you have to love the night; you have to embrace the night. And that is exactly what this 28-year-old from Atlanta, Georgia has done. In a 100-mile race like the Javelina Jundred, Rocky Raccoon 100-Miler, Grindstone 100-Mile Trail Run, Keys 100-Miler and countless other races, no one finishes without running through the night.
