It makes not one bit of difference that Andy beat TB last time they played the weather had a large part to play in that result.
I'm not convinced the weather was the deciding factor, but clearly it was very different conditions, and Berdych was very disgruntled and acting hard done by about it. He's going to come in to this match determined to prove a point from the get go.
It's hard not to notice that Federer has his dream group, and that Andy's could have been kinder, but there's not anything that can be done, so I'm reassuring myself with the fact that if he makes it through the heats, he's likely to get an easier semi-final.
I'm also happy that he's playing Monday, Wednesday, Friday as it will give him a day off if he does get to the semis.
