What is the difference between the two-seam fastball and a screwball?

One may throw a “slider,” while another will be throwing a cutter… same pitch different name. Announcers see one pitch and call it one thing where it is often something else. Different pitching coaches even have different names for the same pitches. And if this isn’t enough, different pitches that do the same thing can be thrown different ways with different grips. I am quite sure that I can throw over 120 different variations if I include arm angles different curve grips, different slider grips, different split & forkball grips. For pitchers who don’t have issues throwing strikes but seem to give up a lot of hard-hit balls, a 2 seam may be the best option.

The backspin influences the transfer of the ball’s momentum with the neighboring air in a way that lifting force known as the Magnus Effect overcomes gravitational pull on the ball. This result makes sense as a grip like that would start to resemble a splitter, a pitch known for killing spin and velo. “Pitchers don’t usually consider how air flows over baseballs, propasser and nobody has ever really looked at it on a micro level,” said Smith. “People throw balls and watch where they go, but I don’t think anyone has ever made very careful measurements of what is happening around the ball.” Researchers at Utah State University are breaking down the physics of a new baseball pitch that’s been getting a lot of attention.

If you are throwing against aluminum bats you will notice that the pitch often avoids the “sweet spot” of the bat. One benefit of a four-seam fastball is that it is easy to spot because it has no movement. If you are behind in the count and need a strike, this is a great pitch to use. A risk with throwing the four-seam fastball is that it has no movement. If you place the ball in the center of the strike zone, or a batter’s wheelhouse, you can give up a big hit.

With this pitch, you are using your strength against the batter’s strength in an effort to overpower them. Breaks away from a right handed hitter as it reaches the plate. Faster than a slider but with more movement than a fastball. When the catcher throws down the old number one and calls for a fastball there are a few general rules to be aware of when deciding whether to throw a 2 or 4 seam. Sadly, most of the kids who come to us in high school are cemented into throwing just a 2-seam fastball, a circle change, and a curve.

A 4 seam grip is faster and straighter making it easier for teammates to catch. Because of the arm-side movement of the 2 seam fastball, it works great when it is paired with a sweeping slider or a fading changeup. This causes hitters to hit a lot of ground balls and swing and miss over top of the pitch. Most baseball players were taught at an early age how to throw a 4 seam fastball.

With a two-seamer, the ball moves in the same direction as whichever arm is being used to throw it (meaning a right-handed pitcher gets rightward movement on a two-seamer). Whenever you are trying to elevate the ball in the Red Box or in an opposite arm side Purpose Zone (7/8) a 4 seam is more likely a better option because you want to keep the ball up. When you are throwing an arm-side Purpose Pitch there are a couple different factors to think about. A 2 seamer could give you more movement and help you get the pitch inside further but you also take the chance on the ball moving too far in and hitting the batter. On the other hand some pitchers feel more confident throwing the straight 4 seamer in there and taking movement out of the equation. When a pitch is thrown with a high spin rate and has straight backspin it gives the hitter the illusion that the ball is rising.

Throwing a two-seamer consistently with added horizontal movement by imparting cut on the ball can be difficult to master however, and this type of adjustment is only recommended for higher-level throwers. In this piece we’ll dissect the differences between sinkers and two-seam fastballs and detail how to design a pitch depending on the type of movement you may be trying to create. To grip the two seam fastball, place your index and middle finger along the 2 seams of the baseball. Put slightly more grip on your index finger when the pitch is thrown to help exaggerate the movement from the baseball. The difference was determined when comparing the pitches from a baseball pitching machine and a human pitcher.

While some may perceive it to rise, the four-seam fastball is just a straight pitch. You use it when you are trying to stay ahead of a batter. It’s a great pitch to use if you are trying to overpower a hitter, or if their swing is slow. A two-seam fastball is generally one of a pitcher’s fastest pitches, although it doesn’t have quite the same velocity as a four-seam fastball.

The Blitzball 2-Seamer is thrown like a normal fastball for most people , but some might want to adjust their grip and arm-angle for a little extra movement. A 3/4 delivery is typically preferred for this pitch, but some people like to drop down a little further for extra movement. It doesn’t have the same velocity or rising action as theRising Fastball, but it’s a great pitch to mix in because of its deceptive lateral movement.
