There are so many reasons why I love baseball – I played from a young age through college and it’s my favorite sport to watch so I’ve always followed it very closely. I love it for its little nuances, the strategy involved, the drama of a close game, late innings situation, and its deep history. It should be target pitching machine sitting on the plain leather part of the ball, with the innermost part of the thumb resting on the ball seam at the bottom. This type of throw is delivered with upward rotation of the arm, and with the help of the ‘Magnus Effect‘, which is the act of the ball being lifted, overcoming the gravitational pull.

Overall, there’s a lot of difference between a 2 seam vs 4 seam fastball. Those who want to have a safe play go for the 4 seam fastball as it is thrown in a straight line and harder to play. The 4 Seam Fastball is probably one of the easiest pitches that you can throw. The 4 seam fastball is typically the first pitch that a young player will learn how to throw.

The other variable for movement will be how much you choke the ball in your hand. It’s important to note that changing efficiency in a game setting is much different than doing it in practice. It’s pretty simple when your only goal is to up the efficiency on a Rapsodo. You’re not necessarily worried about the batter, counts or location as much as you would in-game. The first is to try and up the efficiency of the pitch to increase the pitch’s vertical break. Athlete, it is often the case that pitchers are generally unaware of the various grip options available to them.

It is called a 2 seam because when it is thrown, two of its seams are spinning against the air. This makes the ball less aerodynamic and causes it to move (usually to the pitcher’s arm side) based on the spin-axis of the ball. The main difference between a 4 seam and a 2 seam fastball is that a 4 seam is usually thrown harder and straighter compared to a 2 seam which is usually not as hard but moves more.

All of this resulted in a – rather lacklustre – high 4-Seam fastball swinging strike rate of 13.5%. One of the key contributors to Josh Hader’s dominance is his deception. As seen in the picture above, Hader does a great job hiding the ball from the batter behind his body before releasing each pitch.

One of the biggest aspects which set the two fastballs apart is the direction which the ball follows. The 4 seam should head straight to the plate, with very little movement but high speed. The 2 seam can veer slightly to the left for a right-handed pitcher and to the right for left handed players. This is due to the positioning of the ball seams when being held in the fingers.

Maybe there is a connection between his 4-Seam fastball grip and his abnormally high spin rates. All of these pitchers tend to have a release point near or below their shoulders. They also all have a high 4-Seam fastball swinging strike rate above the Major League average which is significant considering many of them don’t throw as hard with their low arm slots. In the end, most of them are established big leaguers and have pitched in the majors for a long time thanks to their high fastballs which play up due to their deceptive deliveries. Conversely, because the four-seamer doesn’t break, it is quite hittable by the quick, “good-eye” batter who can “see” where the pitch will arrive.
