モンテカルロもＡＴＰを訴える

ATP=Association of Tennis Professionals

つまり、「選手組合」です。

ATPのAはアメリカのA、というのは冗談ですので。

clipped from biz.yahoo.com Both players and tournament organizers have complained that the current ATP management is not representing the best interests of tennis and has not given the players or tournaments a real say in the future of the ATP.
