Running out the clock
（重定向自Run out the clock）
In sports, running out the clock (also known as stonewalling, killing the clock, chewing the clock, stalling, or eating clock) refers to the practice of a winning team allowing the clock to expire through a series of pre-selected plays, either to preserve a lead or hasten the end of a one-sided contest. Generally, it is the opposite strategy of running up the score. Most leagues take steps to prevent teams from doing this, the most common measure being a time limit for completing a play, such as a play clock or shot clock.
