What is the Yankee Run Factor? 

The Yankee Run Factor is a fairly simple statistical metric. It takes the "Runs produced" sabermetric created by Bill James and divides it in two different ways.

Equation 1

The first equation is R + RBI - HR / G = Runs produced per game, as indicated in the chart above as YRF/G.

Equation 2

The second equation is R + RBI - HR / PA = Runs produced per plate appearance, as indicated in the chart above as YRF/PA.
