Preceding Context: Some of the increased offensive output can be explained by the 1920 rule change outlawing tampering with the ball, which pitchers had often done to produce "spitballs", "shine balls" and other trick pitches which had 'unnatural' flight through the air. Umpires were also required to put new balls into play whenever the current ball became scuffed or discolored. This rule change was enforced all the more stringently following the death of
Succeeding Context: , who was struck in the temple by a pitched ball from Carl Mays in a game on August 16, 1920 (he died the next day). Discolored balls, harder for batters to see and therefore harder for batters to dodge, have been rigorously removed from play ever since. There are two side effects. One, of course, is that if the batter can see the ball more easily, the batter can hit the ball more easily. The second is that without scuffs and other damage, pitchers are limited in their ability to control spin and so to cause altered trajectories.
