OBR, R3, 1 out. Batter pops up in foul territory beside 3B. F5 breaks to catch popup. R3 had stood on 3B, evidently so as not to get tagged out. F5 crashes into R3 (while standing on base), and can't make catch. Assuming that in umpire's judgement, catch could have been made with normal effort had the crash not occurred, what is the call?

Would the call vary at all in Little League baseball, Fed, or NSA or ASA softball?
