I was trying to stop video and get a still picture.
The catcher stepped over the line and the runner still had a full arms length of room
(maybe more).
Here's the moment right before the catch is made.. The baserunner has already deviated from her path (seen by the awkard lean) and the catcher is straddling the line.
I think the catcher knew that this was the only place for her to stand to catch the ball/make the tag. Regardless, look how far off line that throw was! That's a good 10' up the line...
