More about Inherited Runners Scored Leaders
Those who lead the league in pitching inherited runners scored can result from one or more of the following: 1) the pitcher was ineffective when entering the game with runners on base, and/or 2) the pitcher frequently entered games with runners on base. In the first instance, if a pitcher is largely ineffective he won’t have many more appearances with runners already on base. In the second instance, even if a pitcher is often successful in not allowing inherited runners to score, given so many opportunities for “failure” even the best pitcher will allow an inherited runner to score from time to time.
