Ultimately a straightforward win for...............THE TECHNICIAN.
However rewind, if you will, to game 4 in the 2nd set. Andy is a break-up leading 2-1 in the set. He's then 40-0 on his own serve. Thereafter he just goes AWOL mentally, f@nnying about, and before you know it he's break point down. He's been doing this all year, most notably when he is a break up in the deciding set and going on to lose the match. He got out of jail in that game but against a better player he will be punished.
Go and take as running jump.
Did you watch Djokovic match, not playing at the same standard as Andy. Takes time to adjust to the conditions.
