Alex Rodriguez's batting average over the past 10 games is .179 as the third baseman (7-for-39) continues to struggles since tweaking his oblique muscle.

Yet he's still the leader among regular starters in the Yankee Run Factor. A-Rod produces for 1.214 runs per game, and 0.288 runs per appearance. Those numbers are down from last week's season totals of 1.381 / .322, respectively.

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.
