Cape Town - SA's top ranked golfer Louis Oosthuizen will be the country's sole competitor in the PGA Tour's finale - the Tour Championship.
Only the Top 30 players in the FedEx Cup standings advanced to East Lake this week.
Oosthuizen secured the 27th spot following his T11 finish at last weekend's BMW Championship.
This is the third time Oosthuizen has qualified for the Tour Championship, following his 2012 debut (T23) and his withdrawal in 2015.
However, the 36-year-old finds himself with a mountain to climb should he wish to contend for the title this week.
Thanks to the new Tour Championship format, Oosthuizen will start the tournament on even par, whereas FedEx Cup leader Justin Thomas begins his opening round on 10-under par.
Oosthuizen will tee off in Round 1 alongside American Charles Howell II.
The Tour Championship winner will lift the FedEx Cup trophy and pocket a cool $15m prize.
South Africa's Dylan Frittelli, who played in the BMW Championship, failed to make the East Lake cut after finishing 63rd in the FedEx Cup standings.
