Baseball statistic
Runs created (RC) is a baseball statistic invented by Bill James to estimate the number of runs a hitter contributes to their team.

This formula expands on the basic formula by accounting for a player's basestealing ability. where H is hits, BB is base on balls, CS is caught stealing, TB is total bases, SB is stolen bases, and AB is at bats.

This formula accounts for all basic, easily available offensive statistics. where H is hits, BB is base on balls, CS is caught stealing, HBP is hit by pitch, GIDP is grounded into double play, TB is total bases, IBB is intentional base on balls, SH is sacrifice hit, SF is sacrifice fly, SB is stolen base, and AB is at bats.

Weighted runs created plus (wRC+) takes runs created and adjusts it to account for ballpark factors and the era a player played in.

The same information provided by runs created can be expressed as a rate stat, rather than a raw number of runs contributed. This is usually expressed as runs created per some number of outs, e. g. (27 being the number of outs per team in a standard 9 inning baseball game).

Runs created is believed to be an accurate measure of an individual's offensive contribution because when used on whole teams, the formula normally closely approximates how many runs the team actually scores. Even the basic version of runs created usually predicts a team's run total within a 5% margin of error. Other, more advanced versions are even more accurate.

Win Shares is James' attempt to summarize, in one stat, a player's contributions on both offense and defense.
