Scottie Scheffler eyes history at East Lake, but PGA Tour pros like Spaun, Rory, Fleetwood and a dark horse could flip the FedEx Cup script.

The top 30 golfers in the FedEx Cup standings are still participating in the Tour Championship, but the PGA Tour's final postseason event has new rules. The No. 1 golfer, in this case Scottie Scheffler, no longer starts multiple strokes ahead of the field.

Scheffler's victory in the BMW Championship on Aug. 17, in which he rallied from four shots behind Robert MacIntyre to start the day, was his 13th top-10 finish in a row since tying for 20th at The Players Championship. Nine of them have been top-fives.
