Heard this story before, maybe from the PU

Then and now, no INT, because the batter is only required to vacate the "congested" area and apparently did and did not hinder a play. In fact, it looks like she actually slowed the ball down, making it closer for the catcher.
The catcher not finding the ball seems irrelvant to the INT question.
If you really want a rule cite, I'll try to figure out which nodule of my brain I used.
