I believe in him too after that performance! He was on fire. I don't remember the last time he backed up his serve that well in a GS match - perhaps that set against Blake at Wimbledon when he didn't lose one point on serve.

I really favored Kiefer in this match, especially remembering their 2006 encounter, so this is a great great surprise.
I'd love to see him upset Nalby, Ferrer, Djokovic...
The haircut was all he needec, maybe? He certainly looks more like his 2003 self, aesthetically.
