Federer v Djokovic

Unbelievable match between Federer and Djokovic.  I can't believe that Federer when serving for the match at 40-15 lost.  I hope that anyone who took my advice to back Federer got out when he was up 2 sets to love as I did.  I actually got out of my Federer position and layed him further because I figured if anyone was going to come back it would be Djokovic.  I didn't think he would roll over and lose in three.  I got out of that after the 4th set.
