Pitch Grips: 2-Seam Fastballs
Two-seam fastballs are often classified by their movement to the pitcher’s arm side and some possible downward sink. They can pair with a straight four-seam fastball to either get a hitter to swing overtop of the two-seam or for them to get on top and hit a ground ball.
The grip for a two-seam fastball involve aligning the index and middle fingers of the throwing hand with the closer two-seams of the ball. This grip varies more than a four-seam grip, depending on hand size, comfort of the grip, arm angle, and desired movement.
Two-seam fastballs are generally thrown similarly to a four-seam fastball, but sometimes pitchers throw them with earlier pronation. (Pronation is when the thumb turns down towards the ground.) This wrist movement can result in more armside run, depending on the pitcher.
Here is some spin-rate information on some of the more popular two-seam fastballs:
Pitch Grips: Fastballs
The four-seam fastball is traditionally the first pitch that every baseball player learns. By putting your index and middle fingers across the four seams of the horseshoe, you get the fastest and straightest pitch a pitcher can throw. Four-seam ...
Pitch Grips: Cut Fastballs
Cut-fastballs move opposite of two-seam fastballs, to the glove side of the pitcher. The amount of movement can vary with some cutters moving more horizontally and others both horizontally and downwards. The cut-fastball grip is similar to a ...
Pitch Grips: Changeups
Changeups are intended to be slower than fastballs, often having downwards or down and arm-side run. Changeups also spin slower than fastballs, meaning they have a lower spin rate. The changeup grip can vary a lot, from circle-change grips to ...
Pitch Grips: Splitters
Splitters are similar in nature to changeups. Based off of a wide grip with two fingers, splitters spin significantly less than fastballs, resulting in downward movement and occasional side movement. Because of the wide grip, pitchers are going to ...
Pitch Grips: Curveballs
Curveballs are meant to slower pitches that have significantly more vertical drop than other pitches. Most curveballs move in a 12-6 or 1-7 fashion. A good curveball can be paired well with fastballs to take advantage of tunneling. The curveball grip ...
