Now a max of five can overtake from six. Wost case of 41 (down 3). If Robredo sees off Querrey, that'll be four from five, and no threats left in the top half.
Querrey is out as well so that's only five left - all in Andy's half of the draw. Only four of them can overtake. Worst case is WR40 (down 2) Not bad for a grandslam week when you're on the sidelines!
Chela plays Andy tomorrow morning. and overtakes if he wins
Grosjean plays Nalbandian tonight. He'll then need to beat Mayer or Haas.
Ginepri plays Blake. He'll then need to beat Hewitt or Gonzo.
Mayer plays Haas. He'll then need to beat Nalby or Grosjean and the winner from Berdych & Davydenko's segment.
Santoro plays Davydenko. He'll then need to beat Berdych or tursunov and the winner of Haas and Nalbandian's segment.
There's just Mayer left who can overtake Tim - if he wins his match with Haas tomorrow, and goes on to the semi final past Nalbandian, and Davydenko/Tursunov/Berdych.
Worst case for Tim is a gain of 1 place to WR37. He'll probably stay where he is at WR36!! - up 2 places
