He has to bloody win Memphis to get only get #11, it sounds like such a small movement on the surface but really it's just 1 away from top10 !!
He has to win Memphis and Haas and Berdych both have to flame out in the first two rounds. For whatever reason, the top 10 seems to be delinated right around the 2,000 point mark. So, when Andy joins the 2,000 point club, he will probably be right around the top 10. He still has a way to go to get there. I would guess that it will happen in April or May.
May would be a very conservative estimate. April is more likely. March is possible, if he tears it up in Memphis, Indian Wells, and Miami, i.e. exceeds his seeding in all three tournaments.
