I disagree on 2 points:

1. I don't see how the run can be nullified within the rules.

2. If the IFR is called, everybody in the park knows the BR is out. His continuing to run toward 1B cannot ipso facto be interference. Now if he kept running to 2B and drew a throw, or turned 1B and danced around between 1B and 2B, that's something else. Nothing says that a runner who is put out must stop running or be called for interference.

So to make you address the real issue, make this hit a bunt instead of a swing.

Good point. Or make it a pop that F1 charges and dives for halfway up the 1B line. Or make it runners at 1B and 3B, or 2B and 3B. The IFR is a red herring here.
