Abstract: Foreign substances on the surface of a baseball can alter its delivery and enhance pitching performance. Here, sticky substances are found to increase finger-ball friction which can positively affect spin rate, whereas rosin powder can ensure consistent friction across pitchers, with results differing between baseballs used in the United States and Japan.
