The PGA Tour returns to Colorado this week for the first time in a decade for the BMW Championship, the penultimate event of the FedEx Cup season.

The top 50 golfers in the FedEx Cup points standings battle the altitude at Castle Pines Golf Club outside Denver. Castle Pines is the longest course in PGA Tour history at about 8,000 yards, but after elevation adjustments it will be more like 7,000 yards.

The PGA Tour last visited Castle Pines in 2006 for the final version of The International, a modified Stableford scoring tournament.

“It’s a longer walk, I can tell you that,” said Patrick Cantlay, two-time BMW Championship winner. “By the end of this week, some caddies are going to be tired, with the uphill and downhill walking and the 7,600 yards. The ball flies further, but we have to walk the whole way.”

The top 30 golfers in the FedEx Cup after Sunday’s final round will qualify for next week’s Tour Championship at East Lake Golf Club in Atlanta, where the winner will receive a whopping $25 million of $100 million in FedEx Cup prize money. The top 30 golfers will also receive two years’ exemption from the PGA Tour and access to the four major championships in 2025.

World No. 1 Scottie Scheffler can stay atop the points standings (and start the Tour Championship two strokes ahead of everyone else) if he finishes alone in fourth place or better at the BMW Championship. Xander Schauffele, who won his first two major titles at the PGA Championship and The Open, can overtake Scheffler if he wins and Scheffler finishes tied for fourth or worse on the PGA Tour.

“Fortunately, I had a good regular season, so I can’t rest, I can play conservatively and kind of hold on to my spot,” Schauffele said. “I could win this week and still not take Scottie, just considering how often he finishes in the top 10 and how many points we get.”

Here’s a closer look at some of the golfers in the top-30 bubble and those outside of it who still have work to do at Castle Pines Golf Club, including what ranking they need to finish in to have a chance:

30. Denny McCarthy

With 5,168 FedEx Cup points, McCarthy is just three points ahead of Tommy Fleetwood in the standings. He is on the rocks at the BMW Championship, just as he was last year when he started in the second leg of the FedEx Cup Playoffs. He finished 33rd in the points standings and missed his first appearance at the Tour Championship. He is playing with a torn labrum in his left hip that may require surgery in the offseason, but that didn’t stop him from finishing ninth in Memphis last week.

31. Tommy Fleetwood (Needs a two-way tie for 48th or better to play in the Tour Championship)

The Englishman won a silver medal at the Paris Olympics, but his season on tour was rather mediocre, finishing third at the Masters and 16th at the US Open. He has only three top-10 finishes in 17 starts, and none since his career-best finish in April at Augusta National Golf Club.

32. Chris Kirk (also 42.)

Kirk earned his fourth PGA Tour victory in the season opener at The Sentry in Hawaii. Since then, however, the former Georgia star has only finished in the top 10 once – a tied for 10th at the RBC Heritage in Hilton Head Island, South Carolina, on April 21. He ranks 154th in strokes gained: putting (-.434), which has been a major reason for his decline.

36. Matt Fitzpatrick (alone 25th)

The 2022 US Open winner has been battling an injury to his right thumb that forced him to withdraw from the Olympics after shooting 10-over-par 81 in the third round at Le Golf National outside Paris. He tied for fifth at the Memorial in early June but then finished 36th or worse four times in a row. He did better last week in Memphis, where he finished 18th.

37. Will Zalatoris (two-way tie for 24th place)

Last week’s tied 12th was a positive development for Zalatoris, who has spent most of the last two years recovering from back surgery. He had missed the cut or withdrawn in five of six tournaments before finishing 9-under par at TPC Southwind. Another positive sign: Zalatoris gained strokes off the tee (.445), on approach shots (.114), around the green (.123) and putting (.514) last week.

39. Cameron Young (alone 23rd)

It’s been a season of success for Young, who finished second at the Valspar Championship and ninth at the Masters in the spring. He’s also finished outside the top 50 seven times, including 61st at the FedEx St. Jude Championship. The 2022 PGA Tour Rookie of the Year is one of the best hitters off the tee, but he ranks 142nd in strokes gained: putting (-.288).

41. Adam Scott (twice tied for 20th place)

The 44-year-old Australian’s game has improved over the past month. He was the sole runner-up at the Scottish Open, finished 10th at the Open and 18th at the FedEx St. Jude Championship. He improved from 67th to 41st in FedEx points, putting him in position to return to East Lake Golf Club for the 13th time in his career. Scott made his first PGA Tour appearance in the USA in August 2000 at Castle Pines Golf Club and missed the cut at the International.

43. Max Homa (Solo 18.)

Homa won two consecutive seasons and got off to a promising start with a tied eighth-place finish at the Arnold Palmer Invitational and a third-place finish at the Masters last spring. But it’s been a struggle of late, with Homa missing the cut in his last five starts and finishing 43rd or worse four times. He struggled badly off the tee, hitting just 55.9% of the fairways.

48. Nick Dunlap (alone 11th)

After becoming the first amateur since Phil Mickelson to win a PGA Tour event on Jan. 21 at the American Express, the former Alabama star predictably struggled at times as a rookie pro, missing the cut at the Masters, PGA Championship and U.S. Open. But Dunlap bounced back to win the Barracuda Championship and finish tied for fifth last week, climbing 20 spots in the FedEx Cup point standings.

50. Keegan Bradley (two-way tie for ninth place)

Aside from runner-up finishes at the Sony Open in Hawaii in January and the Charles Schwab Challenge in late May, it has been a rather unspectacular season for Bradley, who will captain the US Ryder Cup team next year. The 2018 BMW Championship winner has finished in the top 25 just once in his last seven starts since finishing five strokes behind Davis Riley at the Charles Schwab Challenge.
