Runner Knocks Ball From Catcher

[EugeneCoug]

I wasn't intending to change any facts. I was adding a few facts and posing a new scenario. I understood that F2 SET UP THREE FEET UP THE BASELINE. Then the ball came. There are two possibilities that spring from that, neither of which are specifically mentioned in the original posting. One, the ball got there way before the runner, such that F2's ill-position could not have reasonably impeded the runner. Two, the ball didn't get there quite that soon. My scenario is the latter of the two.

So, assuming my scenario, a runner might do one of four things: (1) stop, (2) slow down, (3) try to go around F2, or (4) run right into F2. The last one (running into F2), as I understand it, would be the only one that would not result in a run being scored, due to the runner's failure to try to avoid contact. Otherwise, it should be obstruction.

What am I missing?
