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. It’s in the mile-high air south of Denver and is the longest course in PGA Tour history at 8,130 yards.

For players and caddies, it’s like walking Kapalua with views of mountains instead of humpback whales breaching in the Pacific Ocean.

“The ball is going farther, but we’ve got to walk all that way,” Patrick Cantlay said.

And then next week it’s back to steamy Atlanta and East Lake, a course where players won’t be hitting pitching wedge from 200 yards to a downhill par 3 (as Justin Thomas did Wednesday).

If I was to truly say I want to play my best golf at East Lake, this may have been a week where I would have taken off, just because there’s so much emphasis on East Lake,” Scheffler said. “I kind of figured out this year I don’t love playing the week before a major championship. So with East Lake having so much importance in the season-long race, if I was to truly look at my goal at the beginning of the year to win East Lake, this would have a week where I would consider maybe take off, especially with the points lead that I have.”

But he was at Castle Pines, playing nine holes of a pro-am, working on the range in the early afternoon, trying to get dialed in with his swing and make adjustments to the altitude.
