Re: can nalbandian still qualify if he wins everything he can from now til shanghai
Mathematically still possible.
Madrid and Paris are 100 points each. Basel is 50 points. Nalbandian is on 155 points before Madrid. So in theory, his maximum is a possible of 405 points. (Note: with his semi-final in Madrid, Nalbandian has added 45 points to 155, so now he is at 200 points.)
Ferrer is in 6th place with 425 points, so Nalbandian cannot overtake him.
However, Gonzalez is now on 368 points (Madrid QF) in 7th place. Haas, Robredo, Blake, Berdych, Moya, Ljubicic have between 329 and 315 points, and are lying in 8th to 14th place.
So if Nalbandian makes three finals, he will have 155 +70 + 35 + 70 = 330. If Haas, Robredo, Blake, Berdych, Moya, Ljubicic all lose their first matches in Paris, Nalbandian will overtake everyone else and tie with Haas for 330 points.
Realistically, Nalbandian will have to win at one or two of the three titles and be a finalist in the other tournament(s), for him to have a better shot and not rely on everyone losing in their first match in Paris and in St Pete/Basel/Lyon next week.
Based on this, I think will be very very very very unlikely for Nalbandian to make the TMC, even though it is mathematically possible.
