Gosh, Glen, I wonder who wrote that?
Whoever he was, it was brilliant!
IMJ, the catcher was completely screened by the pitcher, and the runner was impeded by the pitcher attempting to apply a tag (legal to impede). The catcher was just standing there and didn't seem to cause the runner to do anything.
I think the coach was hoping for the call because she was in the "base path" without the ball. Of course, the runner would have had to run through the pitcher to get to her.
If anything, the catcher impeded the pitcher trying to get back to make the tag.
