Power–speed number

From Wikipedia, the free encyclopedia

Power–speed number or power/speed number (PSN) is a sabermetrics baseball statistic developed by baseball author and analyst Bill James which combines a player's home run and stolen base numbers into one number.[1]

The formula is:


(It is the harmonic mean of the two totals.)

Power–speed number is displayed as a number with one digit after the decimal point.

James introduced the power–speed number in his commentary on Bobby Bonds, writing "it is so crafted that a player who does well in both home runs and stolen bases will rate high, and his rating is determined by the balance of the two as well as by the total."[2]
