Really! Where in the OP does it note as to what the "other" umpire may or may not have seen?
BTW, in the OP in a softball game, which umpire is going to see anything different from their position?
Here is the
play
Is it a tag, could be. Like U1's view, the replay call is based on a two dimensional view and only the runner is the only one who knows if the tag is made.
The talking heads talk about a base path violation, but I would disagree with that as at the time of the attempted tag, the runner did not venture more than 3' out of the path he established when trying to avoid an INT call which is perfectly legal.
U2 had no view of the attempted tag as the runner's body was between Miller and the tag.
You might also notice that the runner never hesitated in continuing to 2B. Many, if not most, tagged runners almost immediately begin to check-up.
I'm surprised a judgment call like this is permitted to be reviewed, but it appears the crew chief actually suggested going to the review.
Personally, I don't think the catcher would have made an attempt to make a tag regardless, he was going for a force and I doubt he made the adjustment from one set-up to another in the less than one second. The catcher came out and immediately set up with his back to the runner.
But if you want to get back to the possible jeopardy, the automatic reaction would be to call the runner out, return runners and award BR first base.
Here is my issue: If you can use the replay to change the call, the crew should be able to WATCH (not listen to somebody in NY) to determine award/return/position of the runners.
