It's not just me saying this, I've heard many "Experts" say that when Fed mixes it up, chip and charge, serve and volley, play baseline, he confuses these guys and tears them to pieces. Saw that with Djokavich in Cincinnati, and today second set he DESTROYED Murray at the net! It's my opinion that the baseliners are great baseliners, but can't handle true all court playing, I mean it wasn't even close. When Fed hangs back, it seems to be a matter of "Who makes the most mistakes", but when he takes it to them they get confused, they never know if it's going deep or short, and when Fed is at the net his reflexes and experience take over. He's 31, ancient in Tennis years, but when he's aggressive he just shakes up these baseliners, confuses them and takes them out of their game.
