Though there is still one event left in the 2015-16 PGA Tour season, nobody can overtake Dustin Johnson for the No. 1 spot in our power rankings. Oh, I supposed Jason Day could shoot four 59s at the Tour Championship and D.J. could shoot four 80s and I’d have some real thinking to do, but nobody can realistically overtake Johnson.

But first, let’s look at the parameters.

  1. Scope is last two months of tournaments
  2. We value different things but will take into account wins, top 10s and cuts made
  3. If you haven’t played, you don’t get ranked (i.e. Tiger Woods)
  4. Recency matters
  5. PGA Tour will be main focus but bigger European events will be factored in

1. Dustin Johnson (Last week — 2): Johnson locked up a number of titles last week with his win at the BMW Championship. Player of the Year, No. 1 FedEx Cup spot going into the Tour Championship and No. 1 in my power rankings. He has very simply been the best golfer over the last two months and nothing Day does at the Tour Championship can change that. Think about this: From the U.S. Open to now, Johnson has finishes of 1, 1, 9, 2, CUT, 18, 8 and 1. That’s a joke. He’s your final No. 1 in our power rankings. Official World Golf Ranking: 2

2. Jason Day (1): Tough week for Day. He had to pull out of the BMW Championship with a bad back and fell from the No. 1 spot in our power rankings. Day has had a terrific 2016, but you wonder if he won’t look back on it with regret that he didn’t squeeze more wins out of it given that he had one of the great putting seasons of the last 20 years. OWGR: 1

3. Patrick Reed (3): If Reed wins the Tour Championship, he’s going to fly the United States Ryder Cup team to Hazeltine on his back. OWGR: 8

4. Rory McIlroy (4): McIlroy’s cold putter returned at the BMW Championship last week, and he finished T42. The narrative with him is not a difficult one to figure out. OWGR: 3

5. Jordan Spieth (5): Spieth’s strokes gained stats are enthralling. He’s actually putted better than last year, but he’s hit worse approach shots. A top 10 for him at the BMW Championship, and now he could legitimately take home his second straight FedEx Cup. OWGR: 4

6. Paul Casey (17): That’s back-to-back runner-up finishes for Casey in two straight playoff events, and he has played his way into the top five at the Tour Championship, which means he controls his own destiny for the $10 million first prize. It’s unfortunate for him that he can’t be on the European Ryder Cup team this time around. OWGR: 16

7. Adam Scott (14): Speaking of golfers I’m glad do not qualify for the European Ryder Cup team, Scott has back-to-back-to-back fourth-place finishes in the first three playoff events this season after a T4 at the BMW Championship. OWGR: 6

8. Henrik Stenson (6): Stenson skipped the BMW Championship, and I think it’s time to start worrying about whether he will be 100 percent for the Ryder Cup with that bum knee. OWGR: 5

9. Russell Knox (7): Knox has played solidly since his win at the Travelers Championship, and his reward is a top 10 standing going to East Lake. How crazy would it be if the FedEx Cup champion (who also qualifies for the Ryder Cup) was not included in the Ryder Cup? OWGR: 19

10. Jimmy Walker (8): Walker finished T13 at the BMW Championship. He hasn’t been terrible the last few weeks. There have just been better golfers ahead of him. OWGR: 15

11. Brooks Koepka (10): Koepka is one of three U.S. Ryder Cup golfers (Zach Johnson and Rickie Fowler) who did not qualify for the Tour Championship. OWGR: 22

12. Matt Kuchar (15): Last week was a big one for Kuchar, and it came just when he needed it most. A top four followed by a selection to the Ryder Cup team as a captain’s pick. Then he broke some Tiger Woods news (kind of). Big stuff from somebody who apparently doesn’t know how to work the internet. OWGR: 17

13. Phil Mickelson (12): A ho-hum week for Lefty at the BMW. He’ll contend at the Tour Championship, but you have to think he’s already focused on the Ryder Cup. OWGR: 14

14. Ryan Moore (11): Moore played poorly at the BMW Championship where he only shot better than 73 one time. Not what you wanted when you’re trying to claw your way onto the Ryder Cup team. OWGR: 42

15. Justin Rose (13): Rose finished T24 at the BMW but needed to be higher to make it to the Tour Championship because of an injury that kept him out earlier this season. OWGR: 10

16. Emiliano Grillo (16): Grillo is No. 9 going into the Tour Championship. Could be the sneakiest FedEx Cup winner of all time. OWGR: 27

17. Si Woo Kim (18): Kim just keeps quietly grinding. Another top 20 at the BMW Championship and he’s No. 18 going to East Lake. That’s ahead of Bubba Watson, Jason Dufner, Rickie Fowler and Daniel Berger. OWGR: 58

18. Louis Oosthuizen (NR):Solid stretch for Oosthuizen, who did not have the greatest summer ever. He has now finished top 25 in each of his last five tournaments including all three playoff events and the PGA Championship. OWGR: 20
