Leather Ball

The most important part of the ball is the seam. It consists of six rows of stitching that join the leather pieces.
The raised seam acts as a “rudder” for bowlers, allowing them to make the ball deviate (seam movement) when it hits the ground.
In 4-piece balls, the internal stitching holds the quadrants together, while the external seam provides grip for spinners and seamers.
