I think its funny that whatever American gets spit out of that bottom quarter (because at least 4 of the 8 players in the quarter are americans) is not gonna fare well in the semis.
The bottom section includes seven players. Six of them are Americans:
Poor Denis Istomin is stuck in that section. I think it would be hilarious if he managed to escape from that section. He'd have to play three matches against the crowd.
Anyhoo, I do not see any of these six people making it to the finals. Unless the semifinal is Roddick vs. Benneteau, no American will make the final.
