Just looking a little more closely at the pharmaceutical issue. The Internet is full of implications that the Djoker's withdrawal from Monte Carlo at the last minute was down to a massive scaling up of doping tests. Lots of people are also pointing to his increased energy and stamina in long matches.
I'm not saying he's up to anything, but it is a very strange - and sudden - turnaround in someone who once specialised in looking knackered all the time. The official line is that he's now gluten-free, by the way.
Players don't just get tested at tournaments but at random times as well, and I think they need to account for quite a lot of their time well in advance, so that the authorities know when they are available for unscheduled testing. Tennis has had its fair share in the last few years, but the chances of getting away with it are pretty slim. Nole's turnaround is down to many things, but drugs is definitely not one of them. The only thing surprising about his run is his ability to consistently beat Nadal, something which even the mighty fed could not manage in his prime. I still fancy Nadal for RG, as Nole did seem to be struggling physically towards the end of Rome, especially against Andy, and even earlier in the match v Nadal. I seriously doubt he will manage to win RG, but it has been a mind-blowing year for him so far.
