tennis is a unique sport where muscle bulk does not always equate to more strength and therefore power. I'm really happy Andy has decided to return to a more leaner look. His prowess around the court and striking of the ball - especially his back hand - were second to none, now i believe they will be more so because of this change (see video of his 2008 US OPEN semi - final victory against Rafa as proof of what he can do at this weight, and how effortless his backhand was as a result).
I watched that video a few months back. Andy's movement round the court was superb and he's also gained a lot of valuable experience since then.
YAYYYYY Sylvie! Thanks. Now we can let the "experts" make a prediction about Andy's route to the final.
From a quick look, it seems pretty good as far as the SF where he could meet Nadal (I think)
