Roddick's service motion doesnt suit serve and volley at all and neither does his placing of serves, if the opponent gets back his serve it comes back with a very fast speed aswell.
What Roddick needs to do is get back that monster forehand, his backhand has improved alot but his forehand has become a big joke in the process.
Of course he would hit a different serve then. That is part of the secret when guys like him use it. It has to be a surprise when you only intend to use it to throw off the opponent. Take pace off the serve, make it kick up and send it wide out and rush in or so. Needs to improve his arsenal.
Can take the latest full Roddick match I saw when he played Soderling in the final in Brisbane. He was dismantled. He did not have a BP all match. Hit less aces. Hit less first serves. Was not even in the same league from the baseline. He had nothing to offer there but maybe he would have had if he didn't just grind and grind. Now he was just sad and he is only 28 or so. I'm always surprised when I see his age. After all he still got some time to change!
