I see I'm not the only one who's getting really excited for the grass (short) season, hopefully my expectations aren't too high and I won't be disappointed.
The key for Andy in my opinion will be to play a bit more aggressive and to show a more attacking game than he has showed so far this year, despite the fact that it has been a pretty successful year so far. I think he should use his improved agility as an advantage he maybe didn't really have, say, last year rather than, maybe, relying on it too much like he did in certain matches this season.
The serve of course will be crucial, all those kick serves on clay made me miss Andy's 135,140+ MPH huge serves but it was never a problem on grass
If he does that, the chances for an early exit like last year won't be too high. obviously the draw will also play a part.
Good luck Andy!
