SECTION 24. a. Earned runs are runs for which the pitcher is statistically
accountable. An earned run shall be charged against the pitcher when a
runner scores as a result of: a base on balls, a fielder’s choice, a hit, a
putout, a batter hit by a pitch, an illegal pitch, a sacrifice bunt (including
a slap and running slap), a sacrifice fly, a stolen base and a wild pitch
(including a third-strike wild pitch). Earned runs are charged only in the
event that the defense did not have the opportunity to make the third
putout. Earned runs are determined by reconstructing the inning as if
there were no errors or passed balls. The pitcher should be given the
benefit of the doubt in determining the advancement of runners had the
defensive team been errorless. Any pitcher who is replaced is charged
with earned runs for which she is totally responsible.
