Firstly, congratulations to Nadal for winning the trophy here. All the top players were here, and yet again, he remains the last man standing. He simply brushed Berdych aside in the SF & comprehensively dismantled Federer in the final. A quite remarkable performance, as much for the result as for the fact that he didn't have to play his best game in order to achieve it.
Next, the runner up. Federer had a good week here, making it to his first final in a while. Given his opponent in the final, he was unlikely to win. But he played a poor match today. No resistance, failing to convert his chances when he had them. The loss never bothers me, but how a player plays is noteworthy. I thought it was a very disappointing effort from Federer. The final should have been a better contested match, and he simply failed to put up a contest. Janowicz or Paire might have been more exciting to watch.
And I agree with Babblelot - Federer is an excellent clay court player, is experienced & is a great champion. This performance was not excusable, and nothing to do with the surface. More a case of "too good" to Nadal and "poor effort" to Federer.
Nadal's return from an extended absence is a remarkable one. His focus & determination, commendable.
I'm looking forward to the FO. This week highlighted some excellent effort by a number of "hopefuls" Janowic/ Paire/ Gulbis all looked very good out there. I'm hoping that they and some others will make the FO interesting. But I expect Nadal to clinch his 8th title, unless Djokovic can return to play in good form. Other than that, I see no contenders.
