The wrist will not be as loose as on a four-seam fastball. Check out this two-seam fastball from Henderson Alvarez of the Miami Marlins. Here it is in slow motion as he strikes out Curtis Granderson of the Mets…
The other fastball grip is a two-seam fastball. For the two-seam fastball grip, place two fingers close together, in between the seams, with your thumb underneath. From this position, rotate the ball 360 degrees and count the seams. There should be two seams that are part of that rotation. The two-seam fastball has a little more movement to the arm side. That means the ball will fade to the right on its way toward the plate if you’re a right-handed pitcher.
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. If the pitcher is just learning the pitch, use the three finger grip for control. Also, the pitcher shouldn’t think a change up is only effective when it’s missed.
This is typically regarded to as the horseshoe seam because when viewed from above, it resembles the horseshoe U-shape. This type of pitch gets its name from the way that you hold the ball. The parallel seams across the baseball are held across 2 fingers under 2 seams lines. 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!). Use a firm grip with the middle finger pad and thumb, but as mentioned the pitcher must maintain a loose and flexible wrist.
For starters, you could use a four seam or two seam fastball grip, but hold the ball looser and deeper in the palm of the hand. A four-seam pitcher is one example of a fastball. There are many different types of fastballs that you can throw. A four-seam fastball is part of the fastball family but is not the only type of fastball. Pitchers have many choices to make when it comes to what type of pitch they want to throw.
A pitcher with big hands and long fingers has an advantage because he can keep the fingers on top of the ball and the ball won’t slip out as often. With a four-seam fastball, the baseball is balanced and consistent finger pressure creates a straighter flight path to the plate, creating better accuracy and control. A two-seam fastball is generally one of a pitcher’s best switch hitters of all time fastest pitches, although it doesn’t have quite the same velocity as a four-seam fastball. A two-seam fastball is one of the most frequently thrown pitches in baseball. The four-seam fastball is the more basic of the two grips. You will find that the four-seam fastball grip is the same grip most fielders use – because there is little movement to the ball.
Short arm the follow through quickly downward and outside the lead hip. Upon release of the ball, relax the hand, wrist and arm to allow the arm to pronate naturally. This will reduce some of the stress on the shoulder and elbow joints. Grip the ball slightly deeper in the hand than the fastball, but do not choke the ball. Leave a space between the first finger and the thumb. This often causes the hand, wrist or elbow to be out of proper position during the acceleration and release phases, which can lead to injury.
