Jeeno Thitikul had 137 yards left on the 17th hole and almost no room for indecision.
Chanettee Wannasaen had already fired a closing 63. Arpichaya Yubol was still within reach. The breeze had begun moving through Columbia Edgewater, and Thitikul’s advantage had been reduced to the width of one good swing.
She pulled a wedge. The flag sat on the middle tier of the green, so Thitikul started the ball just right of the target, caught the slope and watched it feed toward the hole.
Then she buried the birdie putt.
One hole later, the Portland Classic belonged to her. Thitikul closed with an eight-under 64 to finish at 22-under 266, one shot ahead of Wannasaen and Yubol. Yet the final score only tells part of the story.
Her Sunday showed what this course demands when the wind starts moving. Columbia Edgewater gives elite players plenty of chances to attack, but it also punishes hesitation. The winner has to know when to fire at a flag, when to accept twenty feet and, most importantly, when to trust the shot she has already chosen.
Thitikul did all three.
Sunday started with Thitikul chasing
Thitikul began the final round two shots behind Sophia Schubert and Arpichaya Yubol, then erased the deficit almost immediately.
A birdie at the first settled her. Then came five straight from Nos. 3 through 7.
Six birdies in seven holes.
Suddenly, the tournament had changed shape. Instead of watching the leaders, everyone else had to watch Thitikul. She reached the turn in 31, five under for the side despite a bogey at nine.
For a few minutes, that mistake looked capable of breaking the rhythm. Instead, it set up the defining response.
At the 512-yard par-five 10th, Thitikul found the left rough off the tee. She still had enough of a lie to consider reaching the green, and that decision mattered.
She went for it.
Her second shot found the putting surface, and she converted the eagle. Bogey at nine. Eagle at 10. Two holes, three shots gained back against par.
Thitikul later pointed to that eagle as one of the moments that restored her momentum. More than anything, it showed why the best players at Columbia Edgewater cannot retreat every time a hole becomes uncomfortable.
The course keeps asking for birdies. You either keep answering or somebody passes you.
Columbia Edgewater creates a strange kind of pressure
This is not a golf course that scares players with overwhelming length. Instead, Columbia Edgewater wears them down with choices.
Tree-lined corridors frame the tee shots. Fairways matter because a drive into the rough can take spin and predictability away from the next approach. The greens create their own problems with tiers, slopes and pins that can punish the wrong side.
Then the wind joins the conversation.
A player can stand on the fairway feeling almost nothing while the treetops move above her. Another gust can arrive halfway through the ball’s flight. The flag may suggest one direction while the air higher above the green tells a slightly different story.
For the leaders, those small uncertainties become expensive. At Columbia Edgewater, twenty feet is often fine. Twenty feet on the wrong side of a ridge is not.
A shot that drifts five yards offline may find rough instead of fairway. A wedge that climbs too high can lose its line. A player who changes her mind during the backswing has already made the hardest part of the shot even harder.
That is why wind control at the Portland Classic goes beyond hitting low shots. It is about commitment.
Thitikul never let one mistake become two
The best part of Thitikul’s final round was not the birdie streak. It was the recovery.
She made bogey at nine and immediately answered with eagle at 10. Another bogey came at 12, but again, the round never unraveled.
That pattern matters because Columbia Edgewater produces scoring pressure almost everywhere. Recent champions have set brutal standards: Chanettee Wannasaen won at 26-under in 2023. Moriya Jutanugarn reached 22-under in 2024. Akie Iwai finished at 24-under in 2025. Thitikul needed 22-under in 2026.
Nobody near the lead can spend three holes trying to recover emotionally from one bad swing. A bogey does not just cost a shot. It costs ground while somebody else is making birdie.
Thitikul understood the pace of the tournament. She kept attacking without forcing the issue, and that balance became even more important late Sunday.
The pressure changed on the back nine
Early in the round, Thitikul could chase. Late in the round, she had something to protect.
Those are different forms of golf, and Wannasaen made sure the transition felt uncomfortable.
The 2023 Portland champion surged through the final round with nine birdies and a 63. Her charge pushed the winning target higher and turned Thitikul’s closing stretch into a test of nerve. Yubol stayed close as well.
By the time Thitikul reached the final three holes, nobody could assume anything.
No. 16 demanded a par save, and she made it. Then came 17.
Wannasaen had already attacked the hole from 135 yards and created a birdie opportunity. The breeze was beginning to matter more. Thitikul stood two yards farther back with the championship tightening around her.
This was not a moment for a swing thought. It was a moment for conviction.
She chose the wedge, started it right of the flag and trusted the green to move the ball closer. The approach delivered, and so did the putt.
That birdie restored the one-shot cushion she would carry to the clubhouse.
Headwinds get attention but crosswinds cause the doubt
Headwinds are easy to notice because they take yards away. Crosswinds create different problems because they force players to decide what kind of shot they want to see.
Ride the breeze? Hold the ball against it? Aim farther from the flag? Trust the slope?
The smartest players do not treat every pin the same. They know when the wind gives them permission to attack, and they also know when it is lying to them.
That judgment separates good ball-striking from tournament golf. A player caught between a hard eight-iron and a soft seven does not have much time to negotiate with herself. Once she chooses, the swing has to match the decision.
Thitikul’s 17th-hole approach looked clean because the decision appeared clean. No second guess. No visible fight with the conditions. Just a committed wedge.
That is far more useful for understanding the Portland Classic than a lesson about keeping the ball beneath the wind. The tournament is not won by the player who hits the lowest trajectory. It is won by the player who keeps choosing the right shot under pressure.
Columbia Edgewater rewards position before power
The scoring numbers can make the course look defenseless. It is not.
Players still have to earn the angles that make aggressive golf possible. From the fairway, a wedge becomes an attacking club. From rough beneath the trees, the same yardage can become damage control.
That difference explains why several players during tournament week talked about the importance of driving the ball straight and keeping it in play.
Columbia Edgewater does not always punish a missed fairway with an immediate bogey. Sometimes the punishment is subtler: a player loses the chance to attack.
On a course where winning scores routinely push past 20 under, that can hurt just as much.
Thitikul’s eagle at 10 offered the other side of the equation. Even from the rough, she recognized that the lie still gave her a chance to be aggressive, and she took it.
That was not reckless. It was calculated.
The closing hole still had one more test
Even after the birdie at 17, Thitikul had work left. A one-shot lead makes the 18th tee feel narrower than it looked three hours earlier.
Her final hole was not perfect, and it did not need to be. She found herself with enough work around the green to make the finish uncomfortable, then handled the recovery and made par.
Tournament over.
Her final card read 68, 67, 67, 64. The progression tells its own story.
Thitikul spent three days keeping herself close enough to strike. Then she produced her best golf when the title demanded it.
That is what makes the final round such a useful blueprint for the field. Not because every winner will shoot 64, and not because every championship will turn on a wedge at 17.
Because the same tension will keep returning: attack or wait, ride the wind or fight it, fire at the flag or take the safe side, commit or doubt.
The next winner will face the same invisible test
Columbia Edgewater practically begs elite players to make birdies. Its recent champions have proved that.
But the scoring does not make the course simple.
The trees narrow the picture. The rough changes the next shot. The greens reward precise angles. Then the wind arrives and turns comfortable numbers into judgment calls.
That is where the next champion will separate herself.
The field will know the winning score probably sits deep under par. Players will understand that pars alone cannot keep pace, and every reachable par five will look inviting.
Still, aggression without control will not survive four rounds.
Thitikul showed the balance in 2026. She attacked early enough to erase a two-shot deficit, answered a bogey with an eagle and stayed patient when Wannasaen charged.
Then, with 137 yards left on the 17th, she trusted one of the biggest swings of her week.
That shot did not win the tournament by itself. It revealed why she won it.
When the pressure climbed and the breeze started moving, Thitikul never stopped trusting the next decision.
At Columbia Edgewater, that may be the hardest thing for the field to prove.
