Your call

[Antonella]

R1 on 3rd base, R2 on 2nd. B1 get a hit to the outfield.
R1 crosses home plate and then (on her way back to the dugout) ACCIDENTALLY kick the ball.
It was an overthrow and the catcher was prevented to go for the ball in the backstop zone.
This doesn’t mean she was able to make an out on the subsequent runner or other (B1).
Then R2 crosses the plate, too. And B1 ends on 2nd.

This situation really happened last week and the umpire decided to kill the play and rule ‘Dead ball’ at the moment R1 kicked the ball.
R1 scores regularly, so no penalty on her.
Then the ump put B1 back on first base and declared R2 out because of the interference.

Opinions and suggestions welcome.
