BR rules. Bonus points for anyone who proves that the FED answers would be different. Multiple answers may be correct.

1. R2 scores on a deep single to right. Immediately after he touches the plate though, he retouches it and heads back for third, making it there safely under the tag. The umpire knows that R2, whatever he thinks about himself, did touch third. The umpire should:

1. Wave R2 to the dugout.
   
2. Leave R2 on that base.
   
3. Immediately call out R2 for running the bases in reverse order.
   
4. On appeal, call out R2 for running the bases in reverse order.
   
5. Score the run.
   
6. Cancel the run.
