yes he was probably more tired mentally that he would want to say and accept to recognize.
Sad for him cause its over for him now even if he has one match to play.
He couldnt play his game today, he was too frustrated to make a great match and beat del potro in straight.
Well congrats to him after his big big season with a slam finale, 2 tournaments wins, 1 master serie at home,in france and then a top10 spot giving a qualification in the master cup.
Time to take some deserving rest,go spend holidays in a sunny country.
hope to see him even better(his backhand needs work) in 2009 and especially be injury free!
