judgment call (1948)

“Some umpires apparently seem to have an idea that they are likely to be considered ‘good fellows’ and ‘honest umpires’ if they are frank enough to admit later (on a judgment call) that they ‘guess I booted that one.’ ‘Guessed’ is right. Umpires who second guess themselves are not only leaving themselves open for criticism but are putting the league office on the spot as well for hiring them.” Frank Lane, then president of the American Association, quoted in Sam Levy, “On the First Bounce,” Milwaukee Journal, February 15, 1948, Section III, p4
