A phony baseball metric which is an acronym for Femoral Leverage Under Max Pressure.
Many genius baseball minds within the league use FLUMP, as a way to discern which pitchers which eventually become injured or innefective throughout the course of a season, or a career.
Mike Rizzo, Billy Beane and Rick Peterson are a few FLUMP's largest proponents.
