Our Living Language The central role that baseball has played in American culture is known to all, but is particularly evident in the abundance of baseball expressions applied to circumstances outside the sport. When people say that they have struck out in an endeavor, they are using one such expression. We routinely speak of ballpark figures or estimates, of some unexpected quirk of fate or tricky question on an exam being a curve ball, of minor-league or bush-league players in a field or business, who might one day enter the big leagues. If we can't go to lunch with a person who invites us, we take a rain check. We can go to bat or pinch-hit for a friend. We can be off base about something or so disconnected we are out in left field. When we cooperate we are playing ball, and when we get serious or even ruthless about something, we are playing hardball. Some unfortunate people are said to have been born with two strikes against them if bad things come their way right off the bat. The list could go on and on, but that would only be running up the score.
