Expand the Strike Zone (1950)

“‘Let’s suppose for the sake of argument,’ says Ted [Williams], that I start to swing at pitches which are an inch or two wide of the plate. What does that do? It widens and expands the strike zone for the pitcher, giving him help.’” Arthur Daley, New York Times, March 29, 1950, p40
