I did not see Djokovic match, how was his elbow? I read he had medical time out, however result does not look that he suffered .. His service still slower like usual or he is playing his usual "the best" tennis?
he definitely did NOT play his best -- not the kind we see when his opponents are at the level of the best of Andy, Rafa, Delpo, wawrinka, etc..
but well enough to win - his level , to my view, somewhat weakened towards the end - but STILL was just reflecting how great Nole really is - he could do with just the right timing for the right , critical points and then win it.
he didn't REALLY struggle - imo - just that it was still a little ''under" than his best, .
let's hope he;s gonna be better and feel better from this point on.
