Today a pair of ISA umps working a particular field mentioned to my daughter that she was illegally "Replacing" her foot (one ump in the first game. Both umps in second game).
I watched her and it does look like she's picking up the pivot foot about 1/4" and then putting it back down right before she pauses with her hands together and her stride leaves the pitching plate (normally this is the point she slides her foot to repositing herself for curve balls, etc., if she slides it, there is no appearance that it comes up).
With all the crow-hops and stepping outside the 24" lane I've seen recently, I'm wondering why these two are hung up on my DD. Both said that it won't be a problem unless the other team complains.
Beyond the fact that they're not just calling the IP when it happens, and assuming her motion is as I described, what do you think? Color your opinion by ruleset, please! Thanks!
