I was at the day matches yesterday and aside from getting a hellacious sunburn, I got to see Murray and Fed up close. A couple of things that stood out to me were:
-Murray walks like his back isn't 100%. As someone who has a bad back I can recognize that familiar, grandfatherly, uncomfortable walk. It didn't seem like the back affected his play much but I suspect Murray isn't fully recovered, at least not mentally.
-Murray is a nightmare matchup for Deliciano. I'm not saying anything new here, but Lopez had no chance against Murray. He couldn't get any cheap points on his serve because of Andy's return, his forehand was neutralized by Andy's defense, and his backhand looked absolutely terrible and can't hold up in a rally. Murray doesn't have to play an overly aggressive game to beat Lopez and so never really seemed uncomfortable.
-Murray is a tremendous curmudgeon. Again, nothing new here but Andy is such a sourpuss on court. I was close enough to hear every utterance and most of what he's saying sounds like what would come out of a kid's mouth. At one point he said to himself, "Use your tactics!" to which someone in the crowd said "Yes, do your taxes!" Andy didn't seem to find that very amusing.
-People have been saying this for years, but Andy's backhand is a world class shot while his forehand isn't great. He hits his backhand so naturally; it's a naturally flat and offensive shot while he seems to hit his forehand with a lot of spin the vast majority of the time. The forehand isn't really a penetrating shot and he used it mostly to move Deliciano around, while the backhand looks effortless and powerful.
-Federer's forehand is a gift from the gods. Okay I know I'm just repeating something that's been said by everyone, but Federer's forehand is insane. I've seen Federer play live before but this was the first time I sat courtside and the best way I can describe is forehand is by saying it's like a whip. He generates ridiculous power and flat shots even when he's taking the ball early. His backhand looked a lot less natural unless he was hitting the slice which was a pretty shot. I actually don't know why he doesn't use the backhand slice more against everyone not named Nadal.
Edit: I almost forgot to mention how impressed I was by Andy's size. He's a solid 6' 2" and built like a tank. Also, Deliciano has some massive calves and looked incredibly fit. When he took off his shirt during a changeover someone (hilariously a man) yelled "guapo!"
