Good day, game score was 8 - 10 bottom of the last inning, there were 2 runners on base (2nd & 3rd), game had 2 outs, the batter hits a home run and during his run around the bases his team mates, coach and the manager ran on to the playing field before the runner on 2nd mashed home plate and the batter-runner reached 2nd base. What is the call of the umpire seeing that it is a delayed dead ball situation until the one who hit the home run reaches home and mashes the home plate?
