Actually, he's still not in. He was listed as the first alternate because they had already figured Day won't be there and they did the same with Webb Simpson. Technically speaking, Crane is the 1st alternate, but really, he's 4th in line to get a spot in the field because the field is overbooked. 158 players are either exempt or qualified, and only 156 can tee off. So 2 qualifiers will have to play the waiting game, and they are ahead of the alternates as of right now.
