Every time you play against one of the top guys in the world, it's always a good opportunity to see exactly where your game's at. I have been working with Ivan now for a couple of months. We worked on a lot of things, certain tactics and stuff that would work against Rafa, Novak, and Roger. It would have been, for me, nice to see whether or not those things were working.I have done a lot of practicing, a lot of hitting balls this week, but not a lot of match play. It's been quite a strange week. Hopefully the final, whoever it is, is going to be fit and well and we can have a good match.I guess the one benefit here is that there is a day in between, so I'll have tomorrow to practice with righties. The last of couple days I have been hitting with lefties. I practiced for [30 to] 40 minutes with Paes and Stepanek just to get used to playing righties again.
