MLB to Exapnd Instant Replay in 2014 - UPDATE

[tmagan]

Here is another situation:

Runner at third, bottom of the ninth two out tied game, ground ball to third, runner holds, on the throw to first the runner at third breaks for home, the play at first is ruled out, extra innings. However home team manager challenges and the call is overturned, but the runner at third, who was halfway to home when the batter is ruled out, does he score? The first baseman could say if the first base umpire had ruled the batter safe, he would have then throw home to retire the runner trying to score.
