Late-inning Pressure Situation (LIPS)

Definition

Late-inning pressure situations are defined as any at-bat in the seventh inning or later where the batter's team trails by three runs or fewer, is tied or is ahead by only one run. If the bases are loaded and the batting team trails by four runs, this also counts as a late-inning pressure situation.

Origin

LIPS was developed by the Elias Sports Bureau in 1985 in an attempt to answer the question, "Do clutch hitters exist?"
