The Killer Two Seam Fastball 

The two-seam fastball is the sister of the four-seam fastball. Any pitcher should mix this pitch with his four-seam as the hitter will see different movement from both pitches. This pitch is a “movement” pitch.   This pitch doesn’t move because it is held differently or thrown differently than the traditional four seam; it moves because the pitching grip is different. 

To grip this pitch, use your index and middle finger to cradle the two sides of the seams. This fastball pitching grip is slightly tighter and deeper in the throwing hand than the four seam.   If you refer to the article we have on the four seam fastball you will recall us talking about leaving a big gap between thumb and middle finger to create more momentum on the pitch.

The fingers should be wide enough to cover the seams on the narrow part of the baseball. The two-seam fastball is unique because, at release, the air cuts through the two seams giving it drag on the ball. The ball will cut to the right for a right-handed pitcher and to the left for a left-handed pitcher.   The ball cuts even more when a three quarter or side arm pitcher uses this pitch. 

It is important not to change your natural arm slot to try and get a different rotation on the ball.   Even though you may find some success throwing the ball differently, it is not worth putting your arm at risk for injury.   Besides, you will end up tipping the batter off anyway and they will know what pitch to expect due to different arm angles.   If you have a hard time putting a break on any pitch it typically is a quick fix with your grip.    

The two seam fastball is primarily used when you are slightly ahead in the count. I liked throwing the two seam when throwing inside to a right- handed hitter because the ball cuts right. The four-seam is considered a straight pitch as the two-seam creates more movement. You should get accustomed to using both pitches in your arsenal to mix it up and not be that predictable pitcher batters love to face.
