four-seam fastball
A four-seam fastball, also called a rising fastball, is a pitch in baseball. It is a member of the fastball family. This pitch is gripped across the seams as opposed to the two-seam fastball which is gripped along the seams.[1]
Throwing mechanics
The four-seam fastball is gripped by placing your index finger and middle finger about three-quarters of an inch apart across the seams of the ball. The ball should be supported by the hard part of the thumb in line with the middle finger. The ring finger should be curled around the outside of the ball. The pitcher's finger tips should hold the ball, rather than the palm. When it is released, the ball will spin backwards. More arm speed, finger pressure, and wrist snapping will result in more pitch "rise".[1]
