Adios Grigor, way to limp out. Time for him to regroup and book that spot in London over the next few weeks.
Speaking of which, this fortnight has seen the race close up somewhat. Ferrer, who was 5th before New York, lost in R3. Raonic and Dimitrov were 6th and 7th and both went out in R4, while Berdych (8), Murray (9) and Nishikori (10) all remain in the tournament. A win later tonight and Berdy will leapfrog both of the "next generation" kids. Likewise for Andy if he can find a way past Djoker tomorrow. That scenario would leave a gap of just 205 points between Ferrer in 5th and Dimitrov, outside the qualifying spots, in 9th.
We'll see how it goes, though. Tsonga (11th) is the biggest loser having gone out in the fourth round and lost ground to Murray, Nishikori and probably Berdych, who were his three closest targets ahead of this, the highest scoring tournament left this year.
