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.
The index and middle fingers are now placed in line with the seams with the thumb, again, being placed underneath. This pitch category isn’t known for spectacular results. The average two-seamer/sinker posted a whiff rate of only 6.0%, by far the lowest of any pitch type. And the pitch’s contact management performance isn’t spectacular, either – its’ 99 Adjusted Contact Score is almost exactly equal to league average. In 2019, only two two-seamers/sinkers received “A” grades or better, and they both received “A+” grades.
The con, or hard part, about using the two-seamer is that it can be hard to spot in the strike zone. Once you get comfortable with the general rules shown above it is very important difference between 2 seam and 4 seam fastball that you experiment with both fastballs in all Lokations. We emphasis working on throwing the 2 seamer in Lokations 1-6 and to the arm-side Freeze and Purpose Zones.
We have not tracked gripping the ball across the narrow seams thus far, though we are incorporating more detail in the grip tracker moving forward (including evaluating a one-seam grip). If you believe adding velocity could be critical to your success, check out my conditioning and throwing programs for baseball pitchers of all ages. It’s called the two-seamer because, due to the grip, the batter sees only one pair or horizontal seams spinning, instead of two. Here are some pictures of different two seam fastball grips… The four-seam fastball is the more basic of the two grips and is easier to throw. His pitch-specific Adjusted Contact Score was the very best within this category, and his whiff rate ranked 2nd only to Alcantara.
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. Other than adding a little pressure on the index finger, finger placement is the only real difference between the two. There are no real structural changes in wrist or hand action , so this pitch can be taught at the same time a four seamer is taught very early on. Remember, baseball pitching grips are very important so be sure to give them the practice they deserve. Out of all the baseball pitching grips, fastball grips are the easiest to master and be consistent with. This can be a very easy pitch to learn because it isn’t thrown much different than the four seam fastball.
