Inherited runner by starting pitcher

Way back when, on occasion I would get some small amount (say, $20) to serve as official scorer for AA games. This discussion, revealing my total ignorance of the nuances of scoring, suggests that I was wildly overpaid for such.

 

Yep. MLB Rule 10.16(g): "When pitchers are changed during an inning, the official scorer shall not charge the relief pitcher with any run (earned or unearned) scored by a runner who was on base at the time such relief pitcher entered the game, nor for runs scored by any runner who reaches base on a fielder's choice that puts out a runner left on base by any preceding pitcher."

 

This is like manky x JDV divided by Canadian math.
