I know this wouldn't work, but I was thinking the other day that they could put the "inherited runners scored" stat under the "R" column.
I figured out this idea with my friend a couple of weeks ago, for situations which they should charge inherited runs for:
If a guy gets a single, pitching change, next guy gives up a double it goes on the reliever. Guy gets a double, pitching change, next guy gets a run scoring single it goes on the SP. single then HR goes on the RP.... basically whoever gives up the bigger hit gets the runs... if its like two doubles then they each get half a run.
