I still don't get it, but I didn't see the full play yesterday. What was the call on the field and how did it differ from an appeal? There isn't much to get and its a stupid rule. Before Hammel steps on the mound Zobrist needed to tell the umpire they were appealing. He didn't so the play counted and Smith was called out "incidentally" kind of like being picked off. OK, I give up. My peon brain fails to understand the concept of being out incidentally.
