I believe, correct me if i'm wrong because I don't have my rule book with me, it is a delayed dead ball. If the the runner is safe on the play made by F2, the ball would be declared dead and the runner called out for the interference. If the runner is out on the play made by F2, the runner is out and according to FED rules, the interference is ignored(I HATE that word.) I use FED rules because that's what is used in OK.
