As for Djoko/Murray, I mentioned at the start of the tournament that that was a 50-50 match and it was. It's not that Djoko was playing particularly poorly (even though both he and Murray were playing badly), but that it's an awkward matchup. Murray has defeated Djoko plenty of times on hard courts. His return is just as good, BH just as good, first serve is bigger although he didn't display it, volleys better, and his defense is just as good. If Murray comes to play, that matchup is always going to be awkward and tight.
On another note, the tour might want to take a look at the ugly nature of the Djoko/Murray match to see the future of the tour. Neither player could hit through the other on this court and because of the other's defense. There was no where to go. Every player is going to play like this in the future to maximize their chances because this style of play with today's courts yields results and reduces the variance in results, i.e., no ups and downs really, make the other player win with his offense and if his offense isn't good enough, then you win.
