I also think that no matter which order you enforce them, the manager essentially has 3 options - R1 to third, ball on the batter; BR to first, R1 stays at 2nd; or result of the play (I only mention this because the post doesn't mention what transpired ... did F2 throw the ball into left field? Did R1 make it to 3rd, and BR, this being ball 4, went to first (or heck... kept going to 2nd?))

Two questions: A) wouldn't you enforce these infractions in the order they occurred, and, B) wouldn't this type of CO, stepping on or in front of the plate to retrieve the ball, be an immediate dead ball because of the 8.1.D.3 EFFECT?
