Before I state the play this is from a high school baseball game I was working last week and yes it did happen. It’s baseball and rules are different but I’m curious to see how others would rule on this play.
Bottom of the last inning, bases loaded with one out. Home team is down by two.
Batter hits a deep fly to left center. Left and center fielder converge at the wall, ball goes over the wall. Walk off home run!! (It’s not hit and sit, home runs are run out)
Runner at third scores.
Runner at second runs over to the batter-runner who’s running tomfirst and starts celebrating. He’s out for vacating the base bath. Two outs.
The batter-runner for some strange reason passes the runner who was on first and was between first and second. The batter runner is out. Three outs.
Ball game. Visiting team wins 6-5.
Or is it ballgame??????
Even if you only umpire softball or don’t umpire feel free to tell us how you would rule on this play.

Its a bad outcome, but you are correct.
The run doesn't score until he rounds the bases and touches home plate.

Id have ballgame also, it sucks for the home team but rules are rules. Hard to believe that they didnt know the rule if they are playing in high school.

I bet a few of the parents of the home team wrongfully so let the umpires have it.

Some did AJC, but it wasnt a big deal.
Even given what happened there was still something that could have occurred that would have changed the outcome.
Anyone want to take a guess?

Wild guess....R2 could still touch 3rd and home. He was not avoiding a tag. R1 could touch second, third, and home. the only out would be batter-runner passing r1.

Not such a wild guess Panther! But R2 is out for vacating the base path. You could also make a case he ran bases in reverse order. Both you cannot do in baseball.
And you are correct about R1!! Amongst the chaotic confusion I had my left arm out—delayed dead ball on a home run, while watching him. Since he was not out on the play and because it was a home run he is entitled to continue on to touch 2nd, third and home. His run most certainly would have counted, thus it would’ve been a tie game. But he stopped and must have figured since there were three outs the game was over and stood there for a minute. Then he ran off the field. My left arm went down, then the game was over.
