Interestingly, Detroit found the only sure fire way to pitch against Williams. In one game they decided to let Williams call the pitches. Birdie Tebbetts catcher for Detroit recalled later that, “We were never able to get Ted Williams out. Finally we hit on the idea of letting him call the pitch. Figured he hit whatever we called, so why not let him in on the act?”
This plan so confused Williams that he went 0-5 in the game.
