In general terms, we should probably divide the results into tiers, because it's an awful lot easier to put up a big OPS over 50 PA than over 500 PA. Not allowing for PA would give a big advantage to American League teams, which we may only see once ever three years, and certainly to those outside the NL West, whom get to face us half a dozen times per season. So, we have three groups of killers: the heat of the moment (50-100 PA), occasional psychopaths (101-250 PA) and mass murderers (more than 250 PA). Here are the top 5, for each category, among active players.
