That's not considering the grass surface, Pakis can play on much higher level on grass. And how can they get an advantage from these courts if they didn't practise on it more than Kiwis and Qureshi just came from Miami?
It looks very fishy that Kiwis started complaining about the courts only 1 rubber down and half-way losing the second.
Grass should suit the New Zealand team too
Khan gains advantage from the court because it turns the match into more of a lottery, as more points are decided at random. On a normal court the odds would be strongly in Sitak's favor. This is simple logic.
You are inferring that the Kiwis a) didn't complain prior to the match or at any point in the first match or earlier on in the second match, and b) that they even complained at all. Neither inference is warranted on the basis of the link I posted, but perhaps you have some evidence you want to share with us.
