Let's say that on the Pirate's catcher's throw to first the first baseman either tagged the runner while he was standing on the bag or stepped on first after catching the ball. That would clearly constitute an attempted appeal, but improperly done since the runner could not be called out either way. The appeal had to be made at second to register the out. But you are only allowed one attempt, so the second one should have been disallowed. However, if the throw went directly from catcher to first to second, with no attempt by the first baseman to render an appeal at first, then the appeal at second should be allowed to stand. I remember a play with Andy Pettitte pitching for the Astros. The batter hit a grounder and the throw got by first with the runner going on to second. However, the runner clearly missed first. Pettitte took his stretch and threw to first without stepping back off the rubber. He was called for a balk and the runner was sent to third. Pettitte got the ball back, stepped off the rubber and made another throw to first. The umps waved off that appeal because you are only allowed one appeal. I am surprised they didn't call him for yet another balk for throwing to an unoccupied base, even though he was off the rubber the second time.
