The regional championship circuit and its prestigious playoff, the President’s Cup, had a new sponsor. It was Carte Blanche, the international credit card for sportsmen, sportswomen, and all people committed to staying fit.
For the third year, the top regional players competed within their respective regions for the chance to vie for the President’s Cup. A regional player, by APTA definition, was any player not ranked nationally after the previous season.
