@panzade,
Part of why I kinda like him, plus the athletic ability along with athletic intuitiveness. He's very emotionally volatile, but in a way, so are Federer and the others. His control of that is a problem. Federer was in a pit of despond and worked himself out.
I say all this like I watched it - no, I read it on the SI site. I mean to go and check the Guardian's play by play - their sports writers are a tad different that ours. I generally appreciate both types of writing. Last evening the difference was close to funny - I was reading SI website live blog (terse, straightforward) with the other window open to the Guardian's freelancer writing about the Seahawks and Packers plays.
Just before the match I was trying to find a game cast or blog for the Open online, but I can't watch some of them (my adobe flash problem, need new computer one of these days) - and the Guardian's blog hadn't shown up yet on their website. I can watch yahoo gamecasts, but they didn't have the open happening.
Anyway, it'll be fun for me to read the G'd'n on it today.

I haven't read that writer before -- we'll see.
