Jason Bay made his 2011 debut last Thursday, and he burned all the energy involved with an inside-the-park home run but little of the statistical glory.

Still, that four-base error gets him some credit in the Mets Run Factor (explain below the chart). In Bay's four games, he was taken over the MRF lead.

What is the Mets Run Factor? 

The Mets 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 MRF/G.

Equation 2

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