When R3 hurdles F2 during a tag attempt and the ball goes into dead-ball territory, what happens if R3 proceeds to touch the plate?

In this scenario, the primary consideration is the status of R3 as he hurdles F2 during a tag attempt. When R3 successfully hurdles over F2, this act itself is not deemed illegal as long as it is done without excessive or dangerous contact. Since the ball goes into dead-ball territory, the play is momentarily stopped, meaning no further action can affect the outcome of the run once R3 touches home plate.

If R3 touches home plate after the ball has gone dead, his run counts because he is considered to have legally completed the action of scoring. The key element is that the contact made during the hurdle does not inherently negate his ability to score, and since the ball is not live, any subsequent actions (like touching home plate) are valid and recognized.

This reasoning affirms that as long as R3 completes the act of touching home plate following the established rules, his run is valid, and he scores. Therefore, the correct answer is that R3's run counts if he touches home plate.
