Fortunately, DeVilliers has nothing to do with grandslams - that's the ITF's domain - and hopefully they aren't as susceptible to the almighty $$.
I don't think there's a chance in hell that the ITF or the Grand Slams themselves would do more than look down at this suggestion for the grubby, greedy piece of shit that it is.
The Grand Slams are in rude health - attendances at all continue to improve, coverage continues to improve, and all are laying out money to enhance their facilities to cater for the fans, for the players and for the elements.
They have awesome tradition behind them that makes them truly special events, and each has its own unique feel that makes it even better.
Tiriac wants it to be like F1 where all the cities fight to host the event year in, year out and those who don't offer enough don't get on the schedule - but fuck that.
