Scottie Scheffler and PGA Tour's best players face a new course in mile-high Castle Pines

Scottie Scheffler could easily have chosen to sit out the BMW Championship to boost his chances of capping off his sensational season with the FedEx Cup. Barring a victory by Xander Schauffele at Castle Pines, Scheffler is assured of being the No. 1 seed who starts the Tour Championship with a two-shot advantage. The course is new to all but two players in the 50-man field — Adam Scott and Jason Day — having last hosted the world's best players in 2006.
