ASA 8.7.J.4

I checked on your cite and was going to slightly disagree with you probably based on us reading the play a little differently. It seems to me that once the F6 gloved the ball 8.7.4.J no longer applies. She's not fielding it after she controls it.
But other than crashing into the fielder, I can't find the rule that actually makes it illegal to interfere with a player attempting to complete a force or tag a runner. So it seems you could have 8.7.Q here, but that seems wrong since the runner didn't really have time to avoid the crash. If a runner were to grab the arm of the fielder to prevent a tag, would we really lack a rule to call the runner out?
