That's a load of BS. You always make an appeal. If anyone has a problem with that, maybe they should teach the players how to play the game properly.
Absolutely agree. Not touching home plate is like dropping the ball before crossing for a touchdown - it don't count.
A couple years ago a J0 18U team coach went off the deep end when the PU received help from his partner and they got the call right. His argument was that once an umpire makes a call it can NEVER, EVER BE CHANGED whether the call was correct or not.
I hear this from the baseball umpires here a lot (i.e. massively against changing a call) but not from softball. Reasons I hear from the baseball umps is that they feel that 'if they change one, then they will question every call from that point on'. And here I was thinking the point was to get the call right.
Assuming this is the right call (and no way can you tell from the video), this is one of the less pleasant positions to be in as an umpire.
I've been there - you've seen it, you know it is not going to go over well if the appeal happens so you pretty much hoping it doesn't... and out comes the coach. Now you have no choice - you saw it.
First time something similar happened to me umpiring I accidentally flinched and one of the fielders saw me and figured it out. Never did that again.
