USU’s results show that the wake of the ball tends to start at a seam. What determines the wake’s angle is the location of the seam on the back of the ball. According to a study by Bleacher Report, Brandon Woodruff has the ultimate four-seamer in today’s game.

A two-seam fastball is often a few ticks slower than a four-seam fastball, but it tends to have more movement. 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). An opposite arm-side Freeze pitch should generally be a 4 seam fastball for pitchers who are not yet learning advanced pitches. If a beginner tried to command the 2 seam in the opposite arm-side Freeze Zone the ball would be more likely to move back over the plate and end in the Danger Zone. You have to be very careful with movement of the ball in the Freeze Zones because both of them border the Danger Zone.
If you have a fastball that moves and one that you can spot, you have a better chance against any hitter. The two-seam fastball is a great pitch to use if you are ahead in the count. Since the ball will “run” or move, it is best not to use it when you are far behind in the count as it might run out of the zone. Place your index and middle fingertips directly over the corresponding ball seams. There’s always a lot of discussions about which one is better and produce the desired results. The true answer is that it depends on the pitcher and batter.
For example, for righties tailing means the ball moves to the right, lefties to the left. The pitch’s magnus force still isn’t that large, but it is large enough for the pitch to be affected and to move more. For it to move more, it loses some velocity compared to a four seam, but the movement is a big payoff. One of the big misconceptions in baseball is that playing the game keeps you in shape to pitch.
As you grip the ball, place more pressure with your index finger. The arm movement of the four-seam fastball is a simple, normal pitch. It does not require the snapping of the wrist or a twist of the arm. Hold the ball so that the seams form what looks like a backward C – or a sideways horseshoe. Using your index and middle fingers grip the top of the “C”. The looser you hold the ball the faster you can throw it.
Your thumb should be directly underneath the baseball, not touching any of the seams below. Once you can comfortably use it in a game, you will love the extra movement and flexibility a second fastball can offer. However, a good pitcher can make up for this loss of speed with the movement generated by the pitch.
It is classified into a fastball pitch category and is typically the toughest ball delivered by the pitcher. There are a few different ways to grip a 2 seam fastball. Knowing when to throw a 2 seam fastball compared to a 4 seam fastball is an important skill to harness. If you are behind in the count, it might not be wise to throw this type of pitch as it may “run away” from the strike zone. Knowing when to throw a proper pitch when the game is on the line is something a pitcher must master. Knowing when to throw a 4 seam fastball versus a 2 seam fastball can be the difference between a strikeout, ball, or a base hit (or more!).
Let’s dig into those two pitchers a little more deeply. Take note of the speed, movement, and break of the ball. Don’t worry about where the baseball is shown in the the strike zone. You can throw a fastball in the middle of the strike-zone like the one illustrated, or you can throw one high and away from the batter. There are many differences between four-seam and two-seam fastballs that make a real difference in how they will work.
