Some good comments. Do you think it is a confidence issue with him? His unwillingness to go for his shots on a more consistent basis I mean. Regardless, he certainly has a more developed and sophisticated game than he is given credit for. With regard to this tournament, I just hope the Argentine and the Scot can win through to the quarters so we can finally see them play again.
Confidence certainly plays a part; it's one of the downsides of getting constantly injured, it affects a player's confidence/doesn't allow him to build momentum. As of right now, he's dealing with on-going left wrist pain, which is why he's abusing the BH slice - might turn out to be a blessing in disguise, his BH slice has become really good. Ultimately, it all comes down to his health; unless he manages to stay fit for prolonged periods, it will be very hard to gather the confidence and momentum to really push for another big title. His game is definitely more sophisticated than a lot of people give him credit for: I'm pretty sure the people who think he just bashes every ball for a winner don't really watch him play. In the past year, due to physical impedements, he has even reached QF/SF in big events by slicing most BHs and even using drop shots to good effect. But of course that in order to challenge the top players in the game, all incredible movers, he needs much more than that - he needs to pull the trigger much more often, needs to be on top of his game fitness and confidence wise basically.
As for this tournament, I think we'll finally have Murray vs JMDP. Chardy ruined that the last two times and he lost to Phau today - that's a definitely a sign that it's destiny
I expect JMDP to beat Phau and Almagro/Haas definitely (Haas is a great matchup, Almagro always chokes vs top players). Murray should take care of Lu easily and although Nishikori could challenge him, I'd expect Murray to win.
