Yeah, no doubt that he'll try to play in Halle if he wants to take on Wimbledon. We'll see about Munich though.
Ok, he might be in the team, in case he he's ready to play, but nevertheless I doubt that Kuehnen will want to risk losing just to give Kiefer some match praxis. So Kiefer might serve as a training partner, but nothing more. Unless he kicks ass on previous clay events, of course.
