ATLANTA (Reuters) - Jordan Spieth's twin win in the Tour Championship and FedExCup playoffs aptly ended a magnificent PGA Tour season for himself and the sport of golf which has enthusiastically embraced a new 'Big Three.'

Spieth, 22, put his stamp on the 2014-15 season with five titles, including wins at the Masters and U.S. Open, a record $12 million in official PGA Tour earnings plus the $10 million FedExCup bonus, and the low adjusted scoring average.
