Strangely, I find the baseball rules kind of arbitrary. For example, they always say "you can't assume the double play"...this applies both to a poor relay throw where one out is recorded but the second is errant (an error cannot be applied) and to scoring decisions--if that presumed double play would have ended the inning, runs scored after that are still earned.

What's odd is that in the above case, all kinds of stuff was assumed, in terms of what happened after Gott reached on an error. Frankly, when there were two outs, assuming that the inning would have been over if Gott had been "gott"en out (no put intended...ok, pun intended), long after his run had scored, is very odd.

The first run was unearned because Gott reached on an error. The second run was earned because it would have scored even if the leadoff hitter had been retired (i.e., no error). The last two runs were unearned because they scored after there should have been 3 outs in the inning. This happens all the time.

See rule 10.16 for more on determining Earned Runs. Here is a portion of it:
10.16 Earned Runs And Runs Allowed
An earned run is a run for which a pitcher is held accountable. In determining earned runs, the official scorer shall reconstruct the inning without the errors (which exclude catcher's interference) and passed balls, giving the benefit of the doubt always to the pitcher in determining which bases would have been reached by runners had there been errorless play. For the purpose of determining earned runs, an intentional base on balls, regardless of the circumstances, shall be construed in exactly the same manner as any other base on balls.
