Wonder how far he will drop after the US Open. He should have definitely played 2-3 challengers during this drought to build a bit of confidence. Sad to see things fall apart like this. Couple of these matches he blew.
DY has 785 points at the moment, making him the #57 player in the world. He loses 625 points during the remainder of 2012, the bulk of which came from Washington DC, the US Open, and Bangkok. If he doesn't add a single point, he will end 2012 with 160 points, equivalent to around #280 in the world
But maybe he will win some matches. Maybe not an ATP-level match, but he will soon be relegated to Challengers, where I assume he can be more successful. Assume he adds 100 points, winning a few rounds here and there, maybe getting to QF's or SF's. He will end 2012 with 260 points, equivalent to around #188 in the world
That's the range I put him at by the end of the year - from #188 to #280.
