Adam Scott remains on track to qualify for the rich Tour Championship 20 years after winning golf's season-ending showpiece.
In another extraordinary display of longevity, 46-year-old Scott retained 27th spot in the season-long points race after opening the second FedExCup Playoff event with a two-under-par 68.
Rory McIlroy, Americans Gary Woodland, JJ Spaun, Chris Gutterup and two-time US Open champion Wyndham Clark set the early pace with opening six-under 64s at the BMW Championship in Missouri.
