I am a baseball coach who also officiates basketball. I witnessed the following play in a baseball playoff game and would like some expert analysis:

Tie game bases loaded 1 out in the 7th Inning (NFHS). BR attempts squeeze, gets bunt down and touches 1st base. R3 touches plate, but R2 and R3 fail to touch 2nd and 3rd respectively and join in a celebration on the IF. If there is no appeal by the defensive team, can R2 and R3 be declared out for abandonment, and if so, would the run score?
