2 outs defense leaves field...call?

[MD Longhorn]

OK, been thinking about what I said earlier about ignoring the touch of third because the runner was not actually running the bases. And I agree it's problematical.

However, take this a half-step further.

Instead of third - for some reason R1 heads toward home, perhaps to pick up a discarded bat or something. She inadvertently touches home plate, then proceeds into the dugout, with the defensive team leaving the field as well.

If you consider touching 3rd in the OP as a baserunning touch, where runner needs to return to 2nd before 1st... then in this sitch, her touch of home was a SCORE. The defense leaving the field would mean they cannot appeal the 2 missed bases.
