SOUNDBITE: (English) Novak Djokovic, defeated Marin Cilic 6-0, 6-1, 6-2:

"Well, obviously it felt great to be able to perform as well as I did today at this stage of a tournament, again, knowing that Marin carried that injury for last couple of matches. I didn't allow that fact to distract me too much. I just wanted to concentrate on what I needed to do on the court and come out with the right intensity, make him move, get as many, you know, returns back in play. All in all, it was from my side a very solid match, and I take that as a confidence booster for the final."

SOUNDBITE: (English) Roger Federer, beat Stan Wawrinka 6-4, 6-3, 6-1:

"I mean, I always thought I had a decent serve with variation, to be quite honest. I definitely had better and worse days before, but now it seems like I'm able to, you know, just serve maybe better consistently maybe. I'm not sure if that's the case, but definitely also talking about faster conditions in Cincinnati and also now here. I'm using conditions to my advantage, it seems like. I hope I can serve equally good, you know, come Sunday."
