Another very impressive display from Djokovic. Mayer didn't play badly but he was the witness of some fantastic returning that has won Nole so many matches and slams over the past few years. I think he's looking unstoppable and although Federer got through more comfortably than I thought against Youzhny, I really can't see him troubling Djoko.
As for the Murray vs Ferrer match. It's been an enjoyable battle between two great athletes and returners of the game. Credit to Murray for fighting back from 5-2 down in the first set, but Ferrer held his nerve in the tie break to win the set. I hope we see a four/five set match but I fear another three set demolition for Murray here.
