Maybe he's already preparing himself for another run at the Wimbledon title.
I dislike Roddick, but again, if he shows up during the grasscourt season serving like this and volleying competently and thus manages to take out either Murray or Nadal, I'll be all for it.
I honestly wouldn't mind if he snuck one in here at the Aussie to be honest. This is the Grand Slam where you get the surprise finalists. Not saying Roddick would be the biggest surprise but he has never been able to get over that SF hump here, and outside of Wimbledon this is his best GS IMO. I just don't see the dominance from the top players anymore we have seen in years past. This is sort of transition phase for tennis if you will. Young crop getting better. Federer on the back 9 of his career. Nadal you never know how his knees will hold up, and it's HC. Novak having his inconsistencies. I think Andy has one, maybe two years to add one more GS trophy to his resume, why not Down Under?
