Catcher's interference is considered E2 -- no issue there. But how do you reconstruct an inning that includes CI? When CI occurs, a runner reaches first base via error -- so if he scores, the run in unearned. But in reconstructing the inning without the error, can you assume an out for the effected batter? If so, then things get easier to score. If not, then the remainder of the inning is important in determining ER.
Here is our scenario:
Walk. 1 on, 0 out.
FC, runner out going to 2B. 1 on, 1 out.
Catchers interference - E2. 2 on, 1 out.
Walk. 3 on, 1 out.
E4, 2 runs score. 2 on, 1 out. <- should have been 2nd out or 3rd out?
K. 2 on, 2 out.
Single, 2 runs score. Unearned. Downhill from there (as is often the case).
Can you help our official scorer?
Thanks.
