I don'tknow quite what is wrong - surely his fingers can't be having this effect. I would far rather Andy played Nadal (which he enjoys anyway) than this very in-form Mardy Fish - but I don't know why I'm saying that. What do you think?
I wouldn't say the fingers are the crucial factor. Nadal is way off, in my opinion. Seems he isn't fully focused on the game right now. Maybe the Djokovic defeats have taken their part too?! Probably it isn't easy facing the fact that there is a man who has taken your crown and you can't do much about it. (Some similatities with Federer-Nadal?)
On the other side, Fish likes this tournament. He was in the finals last year and he plays some nice tennis in the last few months. Regardless, Andy is a "bright player" and I'm sure he will find a way to cope with Fish.
