How do stitches on baseballs affect their flight?
But a baseball in flight is neither smooth nor symmetric because of the stitches. So the center of pressure for a baseball moves slightly about the center of the ball with time, depending on the orientation of the stitches. The time-varying aerodynamic force causes the ball to move erratically.
Are there 216 stitches on a baseball?

Why do baseballs spin?
One of the niftiest tricks up the pitcher’s sleeve is the ability to make a ball curve, or break, in a variety of directions. When the ball spins at the proper speed around its vertical axis, the passing airstream exerts a deflecting force, caused by the rotation of the ball.
What happens to the baseball bat?
During the collision the bat flexes (bends slightly) and after the collision the bat oscillates back and forth indicating that some of the initial kinetic energy of the ball was transferred to vibrational energy in the bat.
