I watched both of Petkovic's matches during Fed Cup. She seems quite comfortable on the surface. If anything, the slower conditions seem to give her more time to line up and smack an even more screaming winner than what she pulls off on hardcourts. Of course, that will help her have a very successful clay court season, culminating in an appearance in the French Open final, where she'll lose, and after which she won't be able to beat a rug ever again. Sound familiar?
