Throwing to F3 playing behind R1. (OBR)

[Lapopez]

I have some confusion about this play mostly from hearing interpretations by TV announcers. I have heard that, based on 8.05(d), this is a balk—-unless F3 is making an attempt to move towards the first base bag. I disagree with this because, in my opinion, a base is either “occupied” or “unoccupied” based on its occupancy by a runner, not a fielder. In my opinion, 8.02(c) is the applicable rule. I would rule NO BALK and apply the penalty noted for 8.02c. Am I correct?
