How Rahm can overtake DJ for OWGR No. 1 this week

By Golf Channel DigitalJanuary 23, 2018, 2:50 pm

Editor's note: Information and text provided by Golf Channel's Official World Golf Ranking expert, Alan Robison.

Despite having fewer worldwide wins, fewer top-5 finishes, fewer top-25 finishes and more missed cuts over the past two years, Jon Rahm is poised to overtake Dustin Johnson for No. 1 in the Official World Golf Ranking with a win in this week’s Farmers Insurance Open. 

The Rise of Rahm is meteoric, but how is this possible? After all, Rahm has five worldwide wins vs. eight for Johnson in the same span? 

We’ll start with the raw numbers over the 104-week cycle of the Official World Golf Ranking. These numbers include a win for Rahm in this week’s Farmers (the only way he could get to No. 1; DJ is not playing):


  Dustin Johnson Jon Rahm
Events   46 40
Wins  8 (1 major, 3 WGCs) 5 (3 PGA Tour, 2 Euro)
Top 5 finishes   20 16
Top 10 finishes  26 19
Top 25 finishes  37 26
MC or 0 OWGR Pts earned  4 7

Johnson leads Rahm in every possible category, so you may be wondering, again, how is Rahm replacing DJ possible? 

To understand this, you would need to understand the Official World Golf Ranking, which is all about the power of math, a recency bias and the divisor.

The ranking system can feel a bit overwhelming, so here are a couple of topline bullet points:

  • The ranking is a 104-week period (two years) that evaluates a player’s performance.
  • Events are given a certain weight and bigger events have a higher point total.
  • Majors are worth 100 points to the winner. The Players champ is given 80 points. From there, you will see events weighted in the 70s for most WGCs, down to 24 for PGA Tour events opposite WGCs and majors.
  • The number assigned to an event has to do with the quality of field – the more top 10/20/50/100 players that are in a field, the higher the weighting.

Next, you can look at how recent the event was to determine its true value to a player. Dustin Johnson’s 2016 U.S. Open victory was given 100 points, but now he’s only receiving 23.9 percent of its original weight. Conversely, Rahm’s win at the CareerBuilder Challenge was only worth 40 points, but because it happened on Sunday, he’s receiving the full allotment of points.

Why is DJ getting 23.9 percent of his U.S. Open total? Doesn’t that seem arbitrary? Actually, the OWGR has an intricate formula to determine the value of events. Any event a player has started in the previous 13 weeks is given full value. For the remaining 91 weeks, events drop off at a rate of 1.09 percent until they eventually fall off. Here’s an example:

  • Event 25 weeks ago: 86.96 percent of value
  • Event 50 weeks ago: 59.78 percent of value
  • Event 75 weeks ago: 32.61 percent of value
  • Event 100 weeks ago: 5.43 percent of value

With a win at Farmers, Rahm would have three victories and a runner-up finish inside the last 13 weeks.  That would total to 175.60, given full-point value. After this week, DJ would only have three events in the last 13 weeks and those finishes are T9-win-T14, for a total of 67.32.

Rahm is taking advantage of the full value for three of his five professional wins.

There is still one more important piece of the formula and that’s the divisor.

The OWGR has determined that each player must have a minimum number of events and a maximum number of events, in order to protect players.

For instance, when Rahm won the Farmers a year ago he received 54 points. It was his 13th event and if 13 had been his divisor he would have had an OWGR total of 4.15, immediately placing him inside the top 20. Instead, to be more fair, it’s divided by the minimum number of 40 events played, giving him 1.35, which was around 110th (Rahm, though, had received enough points in his other 12 events that his win moved him to 46th in the OWGR at the time).

The maximum number is as important as the minimum. Many players compete in up to 60 events over the course of two years. Instead of hurting them by counting every event, the OWGR only counts the 52 most recent events in the 104-week cycle.

Why is the divisor so important? Because math. If a player wins a major (100 points) and has the minimum divisor, that major is worth 2.5 points (100/40). A player winning that same major who has the max divisor (52 events) only gains 1.92 points.

In the case of Rahm and Johnson, it’s Rahm who is taking advantage of his divisor in attaining maximum value for his play. Here’s a table of what it would look like after this week (again calculating for a Rahm win) to help explain:


  Dustin Johnson Jon Rahm
Total points earned:  960.82 557.26
OWGR valued points 493.08 433.39
OWGR divisor/events 46 40
Projected OWGR after Farmers 10.72 10.83

What’s amazing about these numbers is that Rahm is still maintaining 77.78 percent of his original value on the points that he’s earned. As we said earlier, three wins are 100 percent. His Irish Open win is 81.82 percent, while even his 2017 Farmers victory is still earning 56.5 percent of its original value.

On the other side, DJ is only maintaining 51.3 percent of his total points earned.

And there you have it. The math favors Rahm, who is still on the outset of his career. Eventually, it will hurt him. But, for now – and right now – Rahm has an opportunity to take all of these numbers and turn them into the world’s No. 1 ranking.

To do that, the scenario is quite simple: Win this week.

Johnson begins Open week as 12/1 betting favorite

By Will GrayJuly 16, 2018, 5:15 pm

Dustin Johnson heads into The Open as the top-ranked player in the world, and he's also an understandable betting favorite as he looks to win a second career major.

Johnson has not played since the U.S. Open, where he led by four shots at the halfway point and eventually finished third. He has three top-10 finishes in nine Open appearances, notably a T-2 finish at Royal St. George's in 2011.

Johnson opened as a 12/1 favorite when the Westgate Las Vegas Superbook first published odds for Carnoustie after the U.S. Open, and he remains at that number with the first round just three days away.

Here's a look at the latest odds on some of the other top contenders, according to the Westgate:

12/1: Dustin Johnson

16/1: Rory McIlroy, Rickie Fowler, Justin Rose

20/1: Jordan Spieth, Justin Thomas, Tommy Fleetwood, Brooks Koepka, Jon Rahm

25/1: Jason Day, Henrik Stenson, Tiger Woods

30/1: Sergio Garcia, Francesco Molinari, Paul Casey, Alex Noren, Patrick Reed

40/1: Hideki Matsuyama, Marc Leishman, Branden Grace, Tyrrell Hatton

50/1: Phil Mickelson, Ian Poulter, Matthew Fitzpatrick

60/1: Russell Knox, Louis Oosthuizen, Matt Kuchar, Bryson DeChambeau, Zach Johnson, Tony Finau, Bubba Watson

80/1: Lee Westwood, Adam Scott, Patrick Cantlay, Rafael Cabrera-Bello, Thomas Pieters, Xander Schauffele

100/1: Shane Lowry, Webb Simpson, Brandt Snedeker, Ryan Fox, Thorbjorn Olesen

Woods needs top-10 at Open to qualify for WGC

By Will GrayJuly 16, 2018, 4:34 pm

If Tiger Woods is going to qualify for the final WGC-Bridgestone Invitational at Firestone Country Club, he'll need to do something he hasn't done in five years this week at The Open.

Woods has won eight times at Firestone, including his most recent PGA Tour victory in 2013, and has openly stated that he would like to qualify for the no-cut event in Akron before it shifts to Memphis next year. But in order to do so, Woods will need to move into the top 50 in the Official World Golf Ranking after this week's event at Carnoustie.

Woods is currently ranked No. 71 in the world, down two spots from last week, and based on projections it means that he'll need to finish no worse than a tie for eighth to have a chance of cracking the top 50. Woods' last top-10 finish at a major came at the 2013 Open at Muirfield, where he tied for sixth.


Updated Official World Golf Ranking


There are actually two OWGR cutoffs for the Bridgestone, July 23 and July 30. That means that Woods could theoretically still add a start at next week's RBC Canadian Open to chase a spot in the top 50, but he has said on multiple occasions that this week will be his last start of the month. The WGC-Bridgestone Invitational will be played Aug. 2-5.

There wasn't much movement in the world rankings last week, with the top 10 staying the same heading into the season's third major. Dustin Johnson remains world No. 1, followed by Justin Thomas, Justin Rose, Brooks Koepka and Jon Rahm. Defending Open champ Jordan Spieth is ranked sixth, with Rickie Fowler, Rory McIlroy, Jason Day and Tommy Fleetwood rounding out the top 10.

Despite taking the week off, Sweden's Alex Noren moved up three spots from No. 14 to No. 11, passing Patrick Reed, Bubba Watson and Paul Casey.

John Deere Classic champ Michael Kim went from No. 473 to No. 215 in the latest rankings, while South African Brandon Stone jumped from 371st to 110th with his win at the Scottish Open.

Spieth takes familiar break ahead of Open defense

By Rex HoggardJuly 16, 2018, 3:50 pm

CARNOUSTIE, Scotland – As his title chances seemed to be slipping away during the final round of last year’s Open Championship, Jordan Spieth’s caddie took a moment to remind him who he was.

Following a bogey at No. 13, Michael Greller referenced a recent vacation he’d taken to Mexico where he’d spent time with Michael Phelps and Michael Jordan and why he deserved to be among that group of singular athletes.

Spieth, who won last year’s Open, decided to continue the tradition, spending time in Cabo again before this week’s championship.

“I kind of went through the same schedule,” Spieth said on Monday at Carnoustie. “It was nice to have a little vacation.”

Spieth hasn’t played since the Travelers Championship; instead he attended the Special Olympics USA Games earlier this month in Seattle with his sister. It was Spieth’s first time back to the Pacific Northwest since he won the 2015 U.S. Open.

“I went out to Chambers Bay with [Greller],” Spieth said. “We kind of walked down the 18th hole. It was cool reliving those memories.”

But most of all Spieth said he needed a break after a particularly tough season.

“I had the itch to get back to it after a couple weeks of not really working,” he said. “It was nice to kind of have that itch to get back.”
