Runs Created is a statistic invented by Bill James that estimates how many runs a player contributed to his team on offense (that is, how many runs he created with his bat). The basic formula is:
Hits plus Walks
times Total Bases
divided by At Bats plus Walks
Or times on base, multiplied by power, divided by opportunities. Other writers have created more accurate versions of Runs Created since James, but this thirty year old formula is 95% accurate for predicting a team’s runs scored. If you apply the formula to a player, you can estimate how many runs he created for his team just using his hits, walks, total bases, and at bats.
