Defensive indifference

A play in which a runner advances to the next base without a throw from the catcher or without any fielder attempting to cover the bag to accept a throw from the catcher. The runner then does not get credit for a stolen base because his action was not challenged in any way. This usually occurs in a game in which the score is heavily favored towards one team and a runner advancing a base will not make a large difference in the expected outcome of the game... specifically, the ninth inning with two outs, where the objective is simply to focus on the batter and induce him to make the final out.
