The Math / Science

Bill Gilbert's Bases per Plate Appearance (BPA) metric of measuring offensive productivity.   The formula for Bill Gilbert's Bases per Plate Appearance is:

where:

• BPA = Bases per Plate Appearance
• TB = Total Bases
• BB = Bases on Balls
• HBP = Hit Batter
• SB = Stolen Bases
• CS = Caught Stealing
• GDP  = Grounded into Double Play
