Sneak Attack By Roger in action:
He obviously does this to confuse the opponent, not for winners. Returns of this kind are hard to pull off and the shots won’t even be proper ones (then again, how do you return a fast 200+ km/h serve). After the return you’re left at the net doing high speed volley. Since you cannot build up proper shots by playing returns this way I see the whole SABR brouhaha as a fad, but only time will tell. Apparently, Djoko/Becker is not happy about Fedex using this return in the US Open final match. He’s lost, so everybody is happy, right?
