P1 is substituted by P2 with one on base (R1) who reached on hit. The following batter reaches on fielder’s choice with a grounder to second, while R1 reaches second on F4 error (catch). The following batter hits a double that plates both runs. One run is credited on both pitchers, but which thakes the earned run and which the unearned one? I assume P1 the earned and P2 the unearned.
