Brooks Koepka left the 2026 PGA Championship putting like a man fighting the grass instead of reading it. That matters because St Andrews waits in 2027 with the kind of greens that turn small pace errors into scoreboard damage. You can overpower many major championship layouts with a 330-yard drive and a cold stare. At the Old Course, that only gets the ball into the conversation.
The real exam starts after the approach lands. A 60-foot putt has to die near the cup, not drift into six feet of stress. Every long stroke has to stay soft, not jabby. Koepka built his five major titles on power, nerve, and ruthless ball-striking. But the enormous greens at St Andrews demand a completely different skill: lag putting through wind and severe slopes.
His recent form makes the concern impossible to treat as theoretical. At Aronimink, Koepka gained 3.5 strokes on approach in the opening round, but his putter wrecked the card. The same round included 32 putts, two strokes lost on the greens, and a ranking of 142nd in putting. Koepka did not dress it up. “Putter is absolutely horrendous,” he said. “Ball striking is absolutely phenomenal.” Asked about the fix, he reached for a tiny phrase with major-championship consequences: “A little bit of speed, a little bit of confidence.”
At most venues, that flaw can bruise a round. At St Andrews, it can decide the week.
St Andrews leaves a bad putter exposed
Koepka has always looked most dangerous when golf turns physical. Picture him at Bethpage Black in 2019, broad shoulders set, hacking through thick rough with that irritated glare. Think back to Shinnecock in 2018, when the U.S. Open became a wind-battered endurance test and he still walked through it. Those wins cemented his identity: power first, pressure second, emotion last.
St Andrews demands a quieter skill.
On a target-style course, an elite iron player can hide a bad putter for stretches. He can stick a 54-degree wedge to three feet. Then he can drive it into the exact right pocket. Short birdie chances keep the card alive. The Old Course offers far less cover because its hardest questions often come after a player has already found the green.
Koepka has seen both versions. He finished T10 at St Andrews in 2015, improving every round with scores of 71, 70, 69, and 68. Seven years later, at the 150th Open in 2022, he missed the cut after rounds of 73 and 75. Those numbers do not reduce the week to putting alone, but they show how the Old Course can remove a contender through accumulation. One tentative lag. A wrong shelf. Another missed four-footer. Then the weekend disappears.
The par-4 ninth perfectly illustrates this geometric trap. On a 352-yard hole, a Koepka missile can finish near the green and leave a simple 15-yard bump-and-run. Catch the wrong slope, however, and that simple pitch mutates into a 45-foot nightmare. Even with the ball resting safely on the green, a player can be badly out of position.
That is why Koepka’s St Andrews problem cannot be solved with speed alone. The drive may remove yardage. His putter still has to remove stress.
The greens turn good shots into long walks
The most immediate problem Koepka faces is not the wind or the fescue. It is the massive square footage of the greens.
The seven double greens at St Andrews average more than 22,000 square feet. Even when you split those into an 18-hole equivalent, the average remains a staggering 13,500 square feet. A typical American green sits around 5,000, which explains why a shot that looks successful in flight can feel unfinished once it stops.
Koepka can find the putting surface and still stare down a 30-yard lag. The correct line might start 20 feet left of the cup just to borrow a slope. From the fairway, a wedge can look tidy. Up close, the reality shifts. That first putt has to survive humps, scars, and wind-polished edges just to get near the hole.
These surfaces turn lag putting into course management. A 40-yard putt does not ask for the same stroke as a 20-footer. It demands rhythm, not aggression. The player has to add force without adding violence.
This nuance is Koepka’s Achilles’ heel. He looks invincible when pounding a driver, but a balky putter immediately unravels his posture. His confident stride shortens. Soon, the jaw tightens. Another birdie putt starts carrying the residue of the last miss.
Jordan Spieth’s 2015 Open remains the cleanest warning. During the final round at St Andrews, he stood one shot off the lead when he found the par-3 eighth green. Spieth lost all feel for his distance. His birdie putt ran too far, rolled off the green, and left him needing three more strokes. That four-putt double bogey captured the place perfectly. Spieth had not missed the green. He had simply misjudged the pace. The damage was not the swing. It was the speed.
Slow greens can still create fast damage
Modern major setups condition players to fear lightning-fast greens, like Augusta National’s glassy shelves or Oakmont’s severe putting surfaces. St Andrews plays a different trick. During the 2022 Open, the browned-out surfaces looked terrifyingly firm and fast to the eye. Yet they barely rolled at 10.1 on the Stimpmeter.
Scottie Scheffler pointed out the odd contrast at the time. Similar-looking greens in the United States might run at 13 or 14 on the Stimpmeter. St Andrews barely touched a 10.
That mismatch matters. Links turf can look baked and still require a bigger stroke. The tight fescue grabs the ball initially, but the severe slopes can release it aggressively toward the hole. A player sees heat and firmness. His hands feel drag. Then the ground changes the calculation.
Koepka’s recent wording lands hard here. “A little bit of speed” sounds like a minor technical fix in a press room. At St Andrews, it becomes the whole tournament. Speed affects the first putt, the comeback putt, the mood on the next tee, and the willingness to attack future pins.
A cold putter also changes strategy. Koepka cannot fire at every flag if the safe side leaves a 70-foot lag. Chasing a heroic angle becomes reckless if the miss brings a three-putt into play. Power creates options. Poor pace closes them.
For Koepka, the brutal reality is this: 330-yard drives are useless if he keeps three-putting from 40 feet.
Wind breaks the feedback loop
Wind at St Andrews does not only move tee shots. It can alter a putt after impact. That turns distance control into a moving target.
Spieth explained the danger before the 2022 Open. Two putts can leave the blade with the same speed, yet a gust can separate them by 10 to 15 feet. On those greens, one poor lag does not always feel like one poor stroke. Instead, it lingers because the player cannot fully trust what the ball just told him.
This part should worry Koepka. One bad break will not break him. He has won too much to unravel over a single gust. Repeated uncertainty on the greens works differently. It attacks the feedback loop that great players need.
Was it misread? Did he hit it poorly? Could the wind have caught it? Did the slope add more than expected? Should the next putt get more pace or less?
Once doubt creeps into his reads, Koepka loses the intimidating edge that defines his game. His best golf carries the impression that he knows exactly what he wants. He walks quickly. Commits hard. Discomfort rarely changes his tempo.
Poor lag putting forces negotiation. At St Andrews, Koepka will have to stay himself while accepting less control. Any power player struggles with that reality.
The layout will sharpen those calculations when The Open returns in 2027. The R&A is stretching the championship course to 7,445 yards, adding length to the 5th, 6th, 7th, 10th, 11th, and 16th holes. Extra yardage should not unsettle Koepka. The PGA Tour’s 2026 Driving Distance table lists him at 313.0 yards, tied for 29th.
Bunker changes matter more. The R&A is reviving a historic playing route on the 16th to the left of the Principal’s Nose and Deacon Sime bunkers. To defend it, they are layering that side of the fairway with fresh sand traps. Other bunker work touches Nos. 2, 6, 9, and 10.
Those changes influence more than tee shots. They reshape approaches into greens. Safer lines can leave longer putts across slower surfaces whipped by wind. Players with elite pace can live there. A golfer searching for feel can feel trapped before he reaches the green.
If the 16th traps him, the 17th is waiting to finish the job.
The road hole shows the problem cleanly
The Road Hole remains the purest test of nerve and pace. New bunkers can sharpen strategy elsewhere, but the 17th already has all the danger it needs. A committed tee shot must carry over a blind line. The approach demands exact distance. Its green severely punishes any player who putts with too much ego.
Uncomfortable visuals do not bother a man who treats major championship pressure like a personal invitation. The Road Hole offers danger, noise, history, and a finish that can swing a championship. Koepka should welcome that stage.
But the player holding the putter still has to execute.
Strike a putt too firmly on 17, and the ball can drift toward trouble. Baby it, and it may stall before reaching the proper shelf. The famous bunker and road grab the cameras, but the green can do quieter damage. It can turn a sensible par attempt into an awkward bogey without producing any highlight-reel disaster.
If he survives the Road Hole, the 18th sets a completely different trap. The tee shot looks generous. Town buildings press close. The Swilcan Bridge sits behind the moment like a postcard. Then the green and the Valley of Sin demand clean pace while the entire scene tugs at a player’s attention.
This is where Koepka’s Aronimink struggles will haunt him. The PGA Championship numbers were not abstract. His irons were sharp. The flight looked controlled. Enough ball-striking was there to climb. The putter kept wasting the work.
Bring that same feeling to St Andrews, and every long first putt becomes a test of patience.
Koepka can still flip the math
None of this removes Koepka from contention. His 2015 top-10 finish at St Andrews argues against that. His major record argues even louder. Golfers with five majors do not need perfect conditions to matter.
Koepka also understands how to simplify chaos. A low, penetrating 2-iron off the tee can keep him short of the wrong bunkers. On the 13th, the Coffin bunkers sit in the fairway, so he can choose a conservative iron from the tee and remove them from the equation. Around the greens, he can play a low bump-and-run with a 9-iron instead of forcing a 60-degree wedge into a tight slope.
If his putting speed returns, his power becomes lethal again. Cleaner angles and shorter approaches will matter even more on those massive greens. The driver will give him choices. Flighted irons will give him chances. His major temperament will help him absorb one bad bounce without chasing the next flag.
The trouble begins when his putter wastes the massive advantages created by his driver.
A 330-yard drive loses shine if the first putt runs eight feet by. Even a heavy iron into the center of the green feels hollow if the lag dies six feet short. One missed comebacker can be shrugged off. Three of them can change the entire feel of a round.
At St Andrews, the course can simply leave him 65 feet away with the wind in his eyes. From there, he has to judge the opening roll perfectly. Miss that number, and the damage becomes mechanical. The next putt stretches. The target shrinks. Shots start appearing on the scorecard in places where his ball-striking deserved better.
Koepka can overpower almost any modern major venue when the rest of his game cooperates. At St Andrews, he cannot overpower the putting exam. He can swing hard, walk confidently, and find plenty of greens. After that, the math tightens.
If his pace returns, St Andrews gives him enough width and enough angles to mount another major charge. Without it, his mistakes will look ordinary. A safe approach to the fat side of the 17th can leave an impossible 80-foot two-putt. A missed chance at the 18th can turn into bogey without a single bad swing.
At St Andrews, power gets Koepka to the green. Pace decides whether he survives it.
