Gil, Stakhovsky, Kavcic, Hanescu and Kamke isn't bad, maybe Istomin too.
I don't want Harrison, Blake, Malisse, Ljubicic and other qualifier.
Why not Harrison? Harrison is younger, less experienced, and in my opinion less talented. Though, I do think Harrison has better tennis intelligence and a better mental game. As an American I would have LOVED to see that. And IMO, I think it would have been a great match and Dimitrov would end up the victor. I'm curious. Why do you think it was best to avoid him?
Alas, it's not to be.
BTW, there are a lot of interesting possible 2nd/3rd round match ups and beyond. Such as:
Dimitrov (Baby Fed) vs Federer.
Berankis (who many consider Dimi's rival) vs Nadal (Federer's rival).
Harrison (America's future) vs Roddick (America's current star)
Devvarman vs Raonic (The first was a two time college singles national champ for University of Virginia and the Second promised to go to that same university of Virginia but chose to go Professional at the last second instead)
It'll also be interesting to see how Del Potro does.
