Maybe its me but I dont see Mark as a top 500 contender Im afraid; not in singles.
Correct, but it only takes one big week and he would be in with a shout
Given Mark was WR 523 at the end of last year I wouldn't totally discount him in the long term. But for now it would take rather more than one big week to be back in the mix given he has 20 points dropping off on 06/11, taking him down to a total of 26 points, around WR 800.
