Lance in disguise. That is what I think of when I see the two aforementioned. Look at the physique of Muzza at the end of last year to now. The guy has bulked up in a big way. And Lance 2.0 as most of us know has some major question marks. Today's match was a case in point. At the end of 5 sets Murray looked fresh as a daisy and that playing another 5 would have been no issue for him. Granted he was pushing fed around on a string but he had to do some running as well. The guy has added some serious power to his game not to mention serve. My only query is so soon all of a sudden? How have him and Lance developed the ability to not get tired? EPO's perhaps. p.s. On a side note was mightily impressed with the fight the Swiss master showed. At age 31 to run around like a demon for 4 sets was painful to watch for me let alone imagine doing at his age. My respect for him went up after this match. My only regret is his serve percentage. If he had served 70 or 80% he could have won. Why his is serve letting him down continuously? p.p.s Was it just me or did federer tank the 5th. I mean it seemed that he gave it his all in the fourth and preceding sets. Yet either tanked the fifth or for the first time I saw that he maybe got tired. Whatever it was it was not the normal fed in the fifth. He seemed a vacuous shell of himself in the 5th.
