You have coverage??? Well, I would've been watching that if I had the proper channel to watch it on!!! Del Potro won four titles last year during the US Open series, so I'm not surprised he's doing well this year too. I think the man's surface is hardcourt period. But yes, I agree with you too. Del Potro has a great shot at this grandslam title; he will give any of the top players a run for their money.
The competition is held in my hometown,so tv from here broadcasts it, you are aware that by digging a bit you can find webcasts online.
You're one lucky cat. But, concerning webcasts, I have the ATP website saved in my favorites and they're not very useful. I'm all ears (or eyes, if you will ) for suggestions.
