It's fantastic when you're done (and) you're watching everyone else in the locker room sweat it out, but it's very tough when rain interrupts play. A lot of time it can change the momentum. Players get stiff, you're always unsure of when it will stop. And I think certain players are personally unprepared for it at certain venues. At Wimbledon, you're always looking up, like, ?OK, one more game.' I don't think anyone would have expected a long rain delay here in the desert.
