Page "Bill James" Paragraph 15

* Runs Created.

A statistic intended to quantify a player's contribution to runs scored, as well as a team's expected number of runs scored.

Runs created is calculated from other offensive statistics.

James's first version of it was: Runs Created = ( Total Bases * ( Hits + Walks ))/( Plate Appearances ).

Applied to an entire team or league, the statistic correlates closely to that team's or league's actual runs scored.

Since James first created the statistic, sabermetricians have refined it to make it more accurate, and it is now used in many different variations.
