I see that with the US Open seedings to be based on 18th August Andy can end up seeded anywhere between 7( very unlikely) and 11 there. For top eight he would need Gregor to have a very bad event in Cincinnati and for himself to win it (I think). As you see with JWT, getting into that top eight is what is needed for the 500 and 1000 events to avoid the top ten players early on.
Changes to this already. Tsonga losing keeps Andy ranked at 9 next week unless Gulbis does something really special and Andy loses very quickly too. Not a lot of chance of either? Then if Grigor goes out quickly THIS WEEK then Andy has a small chance of overtaking him and getting to be ranked 8. Grigor plays Jerzy J in R2 so I expect him to win.
I feel sorry for JWT but losing after a massive win is the norm for the "nearly men". No insult intended but if one of the very top players wins a tournament then you always expect them to follow up with another? That is the difference.
