Scramble seam

Scramble seam is a type of ball capture (seam bowling), in which the fingers grasp the projectile between the seam. It allows the bowler to give the ball a backspin.

It would seem an insignificant difference (45 degrees) in the seam position, but the ball will behave differently when it rebounds from the field. In the case of scramble seam, it is not very predictable.
