umpire jeopardy ??
 

This occurred in a MLB game.
Runner on 1st, deep fly ball into a deceptive corner of the fence.
U1 calls dead ball, administers two base award.
R1 had advanced to home, BR/R2 stopped at 2nd.
Video review shows the ball never struck a dead ball object, so R1 proceeds home.

If, IF, this happened in a softball game, with video replaced with umpire conference, the ruling appears correct.

BUT, if the umpires judge that BR/R2 only stopped at 2nd because of the dead ball call; could R2 be awarded 3rd based on umpire jeopardy.
Yes, I know, we also have to judge that R2 would have reached 3rd.

He could. But unless there was a misplay in RF 98% of the time in MLB the B-R would stop at 2B so that 's where he should be placed.
