The center of the ball is either cork or rubber. This is wrapped in yarn to bring it up to the correct size and finally tightly enclosed with two pieces of white material (which may be either cow or horse hide) and stitched together. The quantity of yarn used to tie up the cork or rubber may extend to over a kilometer for a single ball. The ball is 9.0 to 9.25 inches in circumference and about 2.86 to 2.94 inches in diameter. Two seams can be seen running across the whole surface of the ball where the hides have been stitched together. These are typically red in color, and are raised from the surface of the ball. This raised stitching act like the wings of the airplane and causes the ball to swerve in the air as it is pitched on its way to the batter/catcher. Through the control of spin on the ball and the stitches, the pitcher manipulates the path and the direction of the spin in the ball. There are balls and balls of course, and some balls have created a history of sorts. The ball which Mark McGwire hit for his 70th homerun in the 1998 baseball season to set a game record was later auctioned off by a fan to a collector for some three odd million dollars creating another record.
