Hi Manu
Yes, I can see from your video that his legs are separate...but his
right foot doesn't seem to actually move forward much at all...until he leaves the ground to strike the ball (like you said)
Actually, in the videos
I was looking at, it seems he changed his foot position a bit over the years, as my videos seem to be of Roddick some time after he
first came on the tour when he
clearly used to keep both feet close together...(he was still wearing his
visor instead of his usual baseball style cap...

So I guess I stand corrected...
Unfortunately, I don't seem to be able to send you a screenshot of the video from the website (tennisone.com) that I subscribe to...It's a really cool website that only costs about $79 US for a whole year...It's got literally
hundreds of quality videos (Much more than Fuzzy Yellow Balls) in real time as well as super-slow motion
and from different angles...I think you would find it
quite useful...
