Stolen base
If the defense does not try to put the baserunner out (for example, if the catcher does not even look his way), the play is called defensive indifference (also called fielder's indifference).  No stolen base is credited to the runner in this case.  Defensive indifference is usually only scored instead of a stolen base when the game is in a late inning and the team with the stealing baserunner is down by more than one run.  MLB Rule 10.07(g) defines defensive indifference.
