From Rafa's site:
Dear fans and media reps,
It has been a long and difficult year where I managed to obtain great results, both on a professional and on a personal level. I have mentioned on various occasions that the tennis calendar has been extremely hard with practically all weeks playing and where it forces players to compete week in week out, making it impossible for a top level player to be 100% on each event.
On a personal level I had as one of my goals to become #1 during this year and competing at so many events might have harmed, specially at the end of the season, my physical condition, taking away the freshness needed to play at the top level of the game on these last events. I don´t know if this has been a mistake or not but the fact is that with the goal achieved I also have to take one of the most difficult and painful decisions.
I have decided not to compete on the Masters Cup in Shanghai. As I say this is one of the most difficult decisions in my career due to the importance of the event and above all, due to the fact of not making possible my will to be with the fans in China and the tournament organizers that always treated me in such special way.
I am deeply sadden and disappointed for my fans around the world that expected to see me in Shanghai fighting in every match. I do expect to be there again in October 09 for the ATP Masters 1000 event in Shanghai.
I know that many people where speculating with this news and even though I have yet not done any test, I can say I take the right decision. I want to recover and be ready for the important Davis Cup final with my country that will be played in Mar del Plata, Argentina. That is also another reason for not coming to Shanghai.
Many thanks to all for your support and understanding.
I am sadden, too.
Not too surprising really, and in the end, a good call by Rafa. Do you think Fed will withdraw now too?
I will say this. Shanghai just lot a good amount of luster.
