Adam Scott is the first of golf's leading names to decide the Olympics is not for him.

The 2013 Masters winner has ruled himself out of contention for Australian selection, citing an extremely busy playing schedule around the time of August's games.

Scott's long indicated little interest in going to Rio for golf's return to the Games, preferring to focus his efforts around the sport's four major championships.

Mark Leishman is likely to the benefactor of Scott's withdrawal and is expected to join world number one Jason Day in Rio.
