Scottie Scheffler can only be removed from the top spot in the FedEx Cup standings by one golfer.
It would take a perfect week from Xander Schauffele at the BMW Championship for him to even have a chance of taking over the top position from Scheffler.
The BMW Championship winner earns 2,000 FedEx Cup points. Schauffele is the only golfer within 2,500 points of Scheffler.
While the math at the top is simple, the calculations around 30th place, the cut off for the Tour Championship, will happen up until the 72nd hole at Castle Pines Golf Club.
