First, all the credit in the world for the plate umpire selling the heck out of the call. Anyone doubt what he had? Second, it appeared to me the catcher was positioning himself for a throw from the first baseman, rather than trying to field the bunt. Thus, I have obstruction on the catcher. If I thought the catcher as well as F3 were trying to field the ball, under (NFHS) 8-4-2-g-1 ) I would protect F3 and still have obstruction on F2. And, I guess we can add that decades-old umpire prayer, "If I'm not right, please God make me look right."
