Hello John! I am one of your follower on YouTube and I really appreciate your videos!! Let me introduce myself quickly Im Gautier, 24y, Im french so baseball is not the most famous sport in there but I really like baseball game. I just started to play so I don’t play very well and your videos help me a lot! I wanted to thank you for that! This is my first time I check your website and it seems very interesting so thank you again for all the stuff you put online!
As a curveball flies through the air, the spin creates an imbalance of air pressure on either side of the ball. According to Bernoulli's principle, this imbalance of air pressure creates lift. When applied to a spinning object, the Magnus Effect holds that the force of lift generated will cause the spinning ball to move in the direction of lower pressure.

Armando Galarraga threw sliders 38.9% of the time in 2008, more than any other starting pitcher in the majors, and Ryan Dempster threw them 32.9% of the time, more than any other NL starting pitcher.[2] In 2008 CC Sabathia had the most effective slider, among major league starting pitchers.[3] Zack Greinke won the AL Cy Young award in 2009 in large part because of his slider, one of the better pitches in all of baseball.[4] In 2011, Clayton Kershaw won the Triple Crown by allowing only a .117 average against his slider.[5]
At the end of this corresponding video, you will look at a short clip from the Best of the Best.  Where a Slider thrown by Clayton Kershaw, is featured from a breakdown video/post I recently did of the lefty.  In slow motion, you can see that he has done everything correctly in his mechanics to enable him to Stay Behind the Baseball, Release it ‘Out in Front, and Throw it Downhill.  As for result, well it speaks for itself.
There are several versions of the Slider, but we will illustrate the cut-fastball version (aka a “Cutter”) because it’s the easiest for most people to learn and throw. The Cutter is gripped similarly to a Two-Seam Fastball (index or middle finger along the Blitzball seam), except the two fingers should be closer together and the ball should be held with an off-center grip (towards the outside half of the ball).

So, when their focus is on adding extension to the delivery and trying to “reach out”, trunk rotation suffers. Because the pitcher is focused on arm extension (the idea of “reaching out”), his body exaggerates that action and forgets that upon landing the trunk must begin rotation followed by flexion in order to maximize all transferred energy so the arm gains maximum velocity.

Athletes will begin the pitching drill by standing at one Speed and Agility Cone, raise their inside foot and balance on the outside foot (athlete lined up on left side raise right foot, balance on left foot). From this single leg position athletes will slightly bend the knee and explosively jump laterally toward the opposite Speed and Agility Cone. Athletes should try to keep a good body position by not allowing the hips, shoulders, or chest to rotate at any point during the jump or landing. Athletes should also not allow the chest to lean forward during the pitching drill. Athletes will land the jump on the opposite leg they jumped with, balancing on the landing leg while raising the opposite knee in a pitching motion. Athletes will then balance on their outside leg (same leg which they landed on) and explosively jumping back toward the original Speed and Agility Cone.
It is important when throwing a slider, or any breaking pitch in baseball, not to come "around" the baseball. When the pitcher "comes around" the ball, the pitcher puts extra tension on his pitching arm to throw that pitch. A slider is thrown with a regular arm motion, just like a fastball. Slider movement is a direct result of the fingertip pressure and grip. The pitcher may visualize throwing his fingers at the catcher in order to improve follow through and finish the pitching motion.
Another more advanced variation of the curveball is the knuckle curveball (sometimes called a spike curve). This is the curveball grip that I used. Thrown the same way as my beginners curveball only you'll tuck your finger back into the seam of the ball. Your knuckle will now point to your target instead of your index finger (in the beginners curve).
A slider is the third fastest pitch in baseball. (The No. 1 fastest is a four-seam fastball and No. 2 is a two-seam fastball.) It's important for pitchers, parents and coaches to learn a proper slider grip and to learn correct throwing technique of a slider to ensure and promote arm-health. A slider is gripped like a two-seam fastball, but held slightly off-center.
When you throw the Curveball, you want to cock your wrist at a slight angle while keeping your middle finger high up on top of the ball so that you can roll your wrist downwards when you release the ball (almost like pulling down the string on a window shade). As a result, the Curveball should spin forward as it approaches the batter, giving the Blitzball a great downward movement. In terms of delivery, some people like to come almost straight over the top to get that great "12-to-6" / Barry-Zito-style drop (drops almost straight down) on their curveball, but this is difficult to do. Most people get better results with something closer to a three-quarters delivery for a "1-to-7" break (a pitch that drops and curves to the side). Try experimenting with different release points and arm slots to find the pitch that works most effectively for you.
3. Elbow: 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 drill is used to develop great pitcher control by having the pitcher throw strikes at varying distances. The drill has a catcher set at a stationary plate. The plate never moves. The pitcher should begin throwing at a distance 1/2 of his normal pitching distance. You should have 6-8 distance markers with the first being at his starting point and the longest being twice his normal pitching distance. The markers should be at 10 foot intervals and in a straight line with the plate. The object of the drill is to develop control by gradually moving toward and away from the targeted strike zone. The pitcher is required to throw 1-3 strikes from each marker before moving to the next. The catcher serves as the umpire. Variations of this drill may be to have 1-3 pitchers working and competing against each other. The drill teaches them to work fast, concentrate, and execute a perfect pitch. Make sure your pitchers are in condition for this drill. They will find that throwing strikes from longer distance requires great mechanics and builds arm strength. Make sure your players stretch and warm-up first.
Throwing a curveball in baseball is a fantastic way to dazzle your friends and baffle your opponents. Most of the technique of how to throw these curveballs is in the grip of the ball and the release. Although it takes a bit of practice, once you’ve put some time and commitment into it, you’ll be throwing steep curve-balls like the pros in no time!

Go through your regular wind-up routine, but stop when you get to the kick, holding at your balance point for three to five seconds. Have a friend, coach, or teammate make sure that your leg is waist-height or higher, or have a look in the mirror. If you have trouble holding the stance for five seconds, practice tightening up your abdominal muscles, bending the leg you're standing on and aligning the height of your hips and shoulders.
Next, place your middle finger along the bottom seam of the baseball and place your thumb on the back seam (as shown in the middle picture above). When this pitch is thrown, your thumb should rotate upward, and your middle finger should snap downward while your index finger points in the direction of your target. This, of course, is the reason this pitch is great for beginners: the ball goes where your index finger points. The beginners curveball helps to align your hand and ball to the target.
To throw start with your dominant hand facing away from the catcher facing sideways.  Bring up your front leg.  When you do this at the same time bring up your throwing arm with the ball facing away from the catcher 90 degrees to your shoulder like an L shape.  Then bring your arm down to your knee and release at the time necessary.  It should look something like the video.  He doesn't bring his arm and leg up at the same time but everyone's throw is a little different.
Master the "two-seam" fastball. Once you effectively use the two-seam grip and arm motion, creating sinking action on the ball, you will be better prepared to throw sliders. For the two-seam fastball, place your index finger and your middle finger directly on the narrow seams of the ball -- the top of the "U" in the stitching. Put your thumb on the bottom of the ball, on the smooth surface of the ball directly under the fingers. Grip the ball tightly to create friction and movement. Use the same arm motion as on a regular or "four-seam" fastball.
Does your son or daughter have slider spin when throwing a fastball? A common problem in youth baseball is not informing kids that slider spin on a fastball is not ideal for throw/pitch efficiency.  How can you identify if your son or daughter has slider spin on the ball in their throws? First thing is knowing what you are looking for when you’re playing catch in the backyard. If your son or daughter is a righthanded thrower, the first good indicator of slider spin is YOU may be catching the ball on the right side of your body consistently pulling the throws across your body.  A slider has a clockwise rotation and spins on an axis that faces to player indicated by the blue line in the gif below. When playing catch you will be able to identify slider spin by seeing a circle in the middle of the ball. For righty or lefty throwers a 4 seam fastball should have close to perfect vertical spin/12 o’clock to 6 o’clock spin. A  2-seam fastball’s axis, in comparison to a righty, points towards 11 o’clock.  For young kids slider spin when throwing a 4 seam fastball is not horrible for them but can become a bad habit to break. Plus we want to have the correct spin on the ball, especially as a pitcher. In this article, we will identify slider spin, what causes it, and how we can help eliminate it from 4 seams and 2 seam fastballs.
Coach Phil grew up in Rye, NY where he graduated from Rye Country Day School before heading to Northwestern University on a baseball scholarship. Phil was drafted by Major League organizations on three separate occasions: first by the Detroit Tigers as a High School Senior, then following his Junior year at Northwestern by the Atlanta Braves, and finally by the Cleveland Indians after his graduation in 1999.Most recently, Phil pitched for the Bridgeport Bluefish of the Atlantic League. His years of pro experience and his commitment to studying the art (and science) of pitching give him a real understanding of what it takes to be a successful pitcher at any level.
A great drill for working on curveball rotation is the snap drill. It can be done anywhere as long as you have a baseball. Take your curveball grip and snap your fingers, making the ball pop straight up from your hand. Really emphasize the pull-down your middle finger creates on the ball. As the ball rises out of your hand, you should see good vertical rotation and minimal horizontal rotation.

For a right-handed pitcher, a curveball spins clockwise as it heads toward home plate, pushing through the air, and slowing by the force of friction caused by the resistance of the air. Because of the ball's spin, air will pass more quickly on one side than the other. In other words, the air will move with the spin of the ball on one side and against the spin of the ball on the other side.
Practice pitching standing up once you get more comfortable with the throw. After practicing on your knees and getting the hang of throwing a curveball, it's a good idea to try pitching while standing up so you can practice throwing with a fuller motion. This is a more realistic representation of how you will actually be pitching when you play.[11]
While this partner is rotating their arm in and out the other athlete will hold the KB Powerbands with both hands extended out in front of their body. With knees slightly bent, back straight, and shoulder blades pinched together this athlete will squeeze their abs and hold this position. As their partner rotates the athlete will feel tension build in the abs. Athletes must keep abs tight to avoid being pulled or rotating the hips or arms.
For these explosive youth pitching drills athletes will need a set of Kbands attached just above their knees. Athletes will move through two phases of this youth pitching drill, tuck jumps and split jumps. This unique combination of exercises allows athletes to focus on building baseball power in both legs while also isolating the legs and forcing them to individually develop these power characteristics.
This drill is a pitching drill in which the young pitcher works at a smooth, rather fast pace, but only throw 50-60%. He should not be allowed to throw full speed. The objective of the drill is to teach concentration and develop great control. The pitcher has to throw 20 strikes before he throws 4 balls. He should be allowed to perform the drill at a shorter distance at first but he should be able to move to his regular pitching distance within a couple of weeks. If he throws 4 balls, he must start over. Be careful to not overwork him. However, keeping the distance short, emphasizing accuracy not speed, and making sure he proper stretches and warms up should prevent any chance of arm injury. With younger players you may want to make the drill a 10-3 drill. He must throw 10 strikes before he throw 3 balls or he must start over.
A right-handed pitcher snaps his wrists in clockwise rotation when delivering a curveball (he grips the ball with his middle finger near the top of the ball and his thumb on the bottom---but releases the pitch with his thumb near the top).  A pitcher throws a slider with smaller wrist-break.  He imparts spin by gripping the ball "off-center" (that is, he grips the ball with his middle finger at "2 o'clock"-- instead of 12 o'clock)
In the world of sports power is defined as the combination of speed and strength. Adding more strength to an athlete will help increase an athletes ability to produce power. However, the greatest gains in power are made when both speed and strength are improved. For example, one athlete may be able to throw a baseball a certain distance, but the ball does not travel at a high speed. Whereas another athlete may be able to throw a baseball very fast, but the ball does not travel a great distance.
Grip this pitch softly, like an egg, in your fingertips. There should be a "gap" or space between the ball and your palm (as shown in the middle picture). This is the key to throwing a good, hard four-seam fastball with maximal backspin and velocity: A loose grip minimizes "friction" between your hand and the baseball. The less friction, of course, the quicker the baseball can leave your hand.
A well-timed curveball can be highly beneficial to pitchers, but a curveball is pretty useless if the batter knows it's coming so that he or she has time to adjust to the swing. For that reason, it's important that pitchers not only master the grip and motion of the curveball but also the secrecy of the grip itself, which is necessary for fooling the batter.
The spinning action created when the pitcher releases the ball is the secret behind the curveball. This spinning causes air to flow differently over the top of the ball than it does under the ball. The top of the ball is spinning directly into air and the bottom of the ball is spinning with the air flow. The air under the ball is flowing faster than air on top of the ball creating less pressure, which forces the ball to move down or curve. This imbalance of force is called the Magnus Effect, named for physicist Gustav Magnus, who discovered in 1852 that a spinning object traveling through liquid is forced to move sideways.
A 12-6 curve ball will break downward more sharply. Place your index and middle fingers between the seams, and your thumb on the bottom of the ball. Do an abbreviated snap as you throw, or release the ball as your hand passes your head instead of following the arm motion all the way through. To account for the sharp break, throw a 12-6 a bit higher than you would a normal curve ball.
The athlete facing their partner will hold the KB Powerbands handle in one hand and raise their arm so their elbow is even with their shoulder and there is a 90 degree angle at the elbow. Athletes will move so there is tension on the resistance band and slowly rotate their hand forward, keeping the elbow and upper arm stationery. Athletes will perform a controlled motion for 4-5 seconds on the downward motion while maintaining a normal speed while returning to the starting position.
Throwing a curveball in baseball is a fantastic way to dazzle your friends and baffle your opponents. Most of the technique of how to throw these curveballs is in the grip of the ball and the release. Although it takes a bit of practice, once you’ve put some time and commitment into it, you’ll be throwing steep curve-balls like the pros in no time!

Why does a curveball curve? How does a pitcher throw a changeup with the same arm speed as a fastball? Baseball is filled with buzzwords that are often used imprecisely. In this series of articles, Mike Richmond explores the baseball’s motion as it travels through the air: How does it behave, and what can a pitcher do to control it? This article looks at the slider to see what causes its very distinctive break.
From the wind-up position have the pitcher rock, turn and raise his leg to the balance position. However, instead of either stopping, or going on to pitch, he now lowers that leg to the ground next to and immediately behind the pivot foot. He should now be standing facing either 3b (rh) or 1b (LH), in good balance before beginning. Now he simply re-raises the non-pivot foot and pitches.
The innovator of the slider is debated, but some credit Chief Bender as the first to use the slider, also George Blaeholder was credited with using it with the St. Louis Browns then called a "nickel curve", in the 1920s.[6] Others have also credited George Uhle with developing the pitch.[7] Bender used his slider to help him achieve a no-hitter and win 212 games in his career.[8] Bender was the first pitcher to win six World Series games.[6]

It's always best to learn proper pitching mechanics early -- and then continue to refine those mechanics as a player gets older and advanced in the game of baseball. This starts in little league. These little league pitching drills can be used as a teaching and training tool to promote and develop proper pitching mechanics. Each little league pitching drill focuses on a specific aspect of the pitching delivery, allowing the pitcher to develop a feel for good mechanics that directly translates into better consistency in games, more strikes and increased pitching velocity.
A pitcher's should stride at a minimum 80% his height towards home plate during his fastball delivery. On the curveball and change-up, his stride should be six to eight inches less than his height. For example, if a pitcher is 5 feet, 10 inches tall, then his stride toward home plate on the release of the baseball should be 5 feet, 2 inches (or thereabouts).
