I don't know who else saw the Australian open match with Cilic, but in the 3rd and 4th set, Roddick realized that his shoulder was not getting better, so he started smacking the ball, off both wings. I'm not sure why he doesn't do this more often. Perhaps he realizes how risky it is. I think he just needs to still find a little more balance between that and his counterpunching game. He is now able to grind it out a bit more until he finds his rhythm, he just needs to use that rhythm to attack when he gets it. I'm not sure what happened in the 5th set of that QF, or what happened against Nadal today.
