I think he has a good chance. After all, four years after his Heartbreaking loss to Nadal, he has still not lost to anyone else in a slam. What an opportunity! He might need some help from the draw, though. It would be good if he can avoid Japanese players, as he tends to struggle with them. Probably because of the same Kamikaze attitude Nadal sports.
EDIT - why the merge, mods?
I agree, worst merge EVER! At least they kept the poll...
