Iowa would be incorrect. Only FPSR is TOP:
"2007 Interps: SITUATION 5: With (a) one out or (b) two outs, the visiting team has a runner on third in the top of the seventh. The game is tied 2-2. R1, on third, gets a great jump and easily scores on a suicide bunt. After R1 has scored, F2 picks up the ball and throws to first in an attempt to get B3 out. B3 is out of the running lane and is hit by F2's throw. Does the run by R1 count? RULING: B3 is out for interference. In (a), R1's run counts because he scored prior to the interference by B3. Had the interference by B3 occurred before R1 crossed the plate, R1 would be returned to third base, the base he occupied at the time of the interference. In (b), R1's run would not count as the third out occurred by B3 before he touched first base. (8-4-1g, 9-1-1a)"
