The biggest threat to Andy before the semi is from Berdych. I hope Stan can take him out in the 4th round. Stan has a 6-5 H2H on Berdych! Whereas Andy has an 8-5 H2H on Stan, 6-2 on hard.
The problem is that Stan hasn't exactly set the world alight since the clay. He might come over all inspired against Berdych, but I have a feeling Berdych will get through. Stan will now prove me wrong
I think, assuming they both get there, Andy will be all right against Berdych. It might be a four setter, but in a slam, especially one that isn't RG, I'd fancy Andy. Andy did beat him last year and it wasn't all due to the wind. Then again, should Berdych feel the urge to go out before the quarter finals, that would be fine.
I still think an opponent of Berdy's needs to stand on the baseline and yell 'DJOKOVIC!'. They should definitely give it a go
