Baseball stitching same pitching method

[baseball] Why is a four seam ball faster than a two seam ball
The holding angle of the four seam ball (4SF) is the same as that of the two seam ball (2sf). Because the finger area of the 4SF that contacts the seam is large, the same pitching method will provide more friction than the 2sf pitching method, resulting in a greater degree of rotation. For the straight ball, the faster the rotation speed is, the faster the theoretical ball speed will be achieved (compared with the fork ball)
What kind of baseball throw is this
The interdigital fastball (fast interdigital fastball, interdigital fastball, and interdigital fastball) is a variation of the interdigital ball. In short, the way of holding the ball is between the straight ball and the interdigital ball. Because the finger can slightly buckle the ball, the ball has more revolutions and the natural ball speed will be faster, but it is usually not buckled on the seam line to reduce the rotation force of the ballHow to sew the baseball seam evenly
