Cricket / Baseball Confused
At a baseball game they may go through 4 dozen or more baseballs. The reason is that any scuff or abrasion on the surface can make it easier for the pitcher to curve the ball when thrown toward the batsman. The umpire will inspect the ball being used frequently to insure it is free from scuffs. If the ball isn't free of scuffs or damage, a new ball will be entered into play.
In my very limited understanding of cricket, the bowler has to bounce the ball when thrown toward the batsman.
OK, I don't understand how any adulteration of the ball could provide any advantage to the bowler.
