He probably will need to achieve at least one QF at one of the remaining masters (Shanghai or Paris). Which obviously is possible but depends on the draw.
I figure he needs at least 500 pts to get there. So unless he wins Beijing
, if he loses to Nole tonite, then he needs more than a QF in masters. Ya, it's a stretch to get to 32, but one can dream
Oh, but do you mean top 40? then 1 QF should do.
