Why do basketballs have fake seams?

Answer 1

It allows the pitcher to impart spin on the ball. If balls were seamless it would be like trying to curve a raquetball. Although you can put a lot of spin on a raquetball, it doesn't really curve until it strikes the wall, then the spin changes the balls direction. The friction of the seams when released from the pitcher's hand helps curve, or in the case of a knuckle ball, jump through the air. The above is a consequence of a Baseball having seams. The main reason a baseball has seams is that there is no way to 'weld' two pieces of leather together. The rules in baseball state (among other things about the ball) that the covering must be made of leather.
