- Placing the fingers on the narrow portion of the baseball is the proper two-seam grip.
- For older pitchers, whether the fingers are outside, on, or inside the seams is all based on comfort.
- The two-seam fastball can be thrown with as much velocity as a four-seam fastball (or near to), but with more movement.
- The movement aspect helps the pitcher with control, and makes it more difficult for the hitter to track for contact.
- For youth pitchers with smaller grips, three fingers may be used for the two-seam fastball: the ring and pointer finger grip outside the narrow seams of the baseball; the middle finger rests between the seams.
