Still not sure exactly what we are talking about here??
If it was crow hopping or leaping the chances that this was the first time in six innings the pitcher did this is probably zero (or was this a sub pitcher and this was her first inning) and choosing to call the violation for the first time, while 100% correct and legal, with a runner at third in the sixth inning is B.S. and well all know it.
Now on the other hand when a pitcher say comes together separate starts moving then stops comes together again and separates and moves again my reaction as an ump was instinctive I don't know that I could even stop myself if I tried, I would stop play immediately the first time every time, then explain the rule if the pitcher or coach was unsure.
Pretty much what everyone with common sense would do.
Guess I have been umpiring wrong all these years. From now on I will make sure to consult with my partner on every call I make to be absolutely sure he saw the same thing I saw.
Novel idea really. This would probably be better than walking the winning run home from a WS game then calling time. Heck looks like even you learned something from this tread, makes it all worthwhile then I guess.
