RP estimates the number of runs a hitter produces for a team. A higher number means that more runs are produced by the player.
It is calculated by adding together runs and runs batted in, then removing home runs.
Critics of runs produced note that the runs factor of the metric makes it so that a players RP can be greatly influenced by the batting order of a team. Being on base before a strong hitter increases the chance of scoring a run, as well as increasing the player’s RP in a way that a player with a weak hitter following them might not benefit.
An alternate calculation of Runs Produced simply averages runs and runs batted in.
There are 2 variations of the Runs Produced formula:
RP = Runs + Runs Batted In – Home Runs
RP = (Runs + Runs Batted In) ÷ 2
A batter has 77 runs, 52 runs batted in, and 13 home runs.
RP = 77 + 52 – 13
RP = 116
Using the original runs produced formula, this player has 116 runs produced.
RP (alternate formula) = (77 + 52) ÷ 2
RP (alternate formula) = 129 ÷ 2
RP (alternate formula) = 65
Using the alternate runs produced formula, this player has 65 runs produced.
