CoogansBluff/All-
In this case, I feel that if the RF had been un-interrupted this would have been a fairly routine F9 and batter would have been out. Sad part of this is that 2nd caused the collision. From what I am reading here, seems the error would have been on RF.
Here's my perspective on these: Who calls who off in this scenario? When I have a team, I practice this with the F3, F4, and F9, and I teach them that F4 is to go all out for the ball until they hear F9 or F3 call her off. F9 has responsibility for making the call since she has a better angle to see both ball and F4/F3. If F9 didn't call her off, then I don't blame F4 one bit for still going for the ball. In my book, for my teams, I would score the E on F9, not F4. So this just depends on how your girls are coached on this scenario.
