Page 70 of the 2010 NFHS case book 9-9-1 Situation I:
R1 is on third and R2 is on first with two outs. When B5 receives ball four. An overthrow at third permits R1 to reach home. In advancing (a) R2 fails to touch second or (b) B5 goes to second base but fails to touch first base.

Ruling: If the defense properly appeals. the umpire will declare in (a) R2 out for missing second base. and in (b) B5 out for missing first base. In either case the run by R1 will not count since the third out of the inning was the result of a force play (8-6-7 Penalty, 9-191 Exception d, 2-1)
