Actually, you can have an appeal for runner missing the plate. The catcher can state to the umpire "she missed the plate" and step on the plate. Whereas the catcher stepped on the plate, she didn't declare an appeal, so that didn't count.
hard to tell from the video, but it LOOKS like the established basepath at the time of the tag attempt is approx. center of the plate.......it also appears she is past the plate and well beyond the back of the batter's box, which i believe should extend 3.5' beyond the center of the plate
the case could easily be made, if our angles on the video appear correct, that she is more than 3' beyond the basepath as established at the point of the initial tag attempt
whether anyone is making that call in real time, I don't know........but were I to come out and plead my case on that play, I guess that would be the case I'd be trying to make......although would I have that depth of knowledge watching in real time from the dugout?
