Closing nerves at the Portland Classic mattered most when Jeeno Thitikul walked off the ninth green with her first real scar of Sunday.
She had spent the front nine tearing through Columbia Edgewater. Starting two shots behind 54-hole co-leaders Arpichaya Yubol and Sophia Schubert, Thitikul birdied the opening hole, then ripped off five straight from Nos. 3 through 7. Six birdies in seven holes turned pursuit into control.
Then she bogeyed nine.
For the first time all afternoon, momentum stopped moving in her direction. She could have tightened up and protected what she had built. Instead, Thitikul walked to the par-five 10th, missed the fairway left and attacked anyway. Her second shot found the green. The eagle putt dropped.
In her post-round press conference, Thitikul admitted she would have happily taken birdie after the mistake at nine. Eagle changed the feel of the round completely.
That response framed the championship. Portland never became a contest over who could hit the longest drive. It became a test of who could keep attacking after Sunday started pushing back.
Sunday became a sprint
Thitikul understood the assignment before reaching the first tee.
“The only things that is in my mind is I have to make birdies,” she said afterward. Columbia Edgewater had given the field too many scoring opportunities for anyone near the lead to settle into defensive golf.
Yubol and Schubert began Sunday at 16 under. Thitikul sat two behind after rounds of 68, 67 and 67. By the time she finished the seventh, the deficit had vanished beneath a rush of red numbers.
Nothing about the opening stretch suggested a player waiting for somebody else to blink. Thitikul forced the issue from the start. She attacked pins, converted chances and pushed the winning number higher before the leaders had time to settle.
The bogey at nine could have changed that posture. No. 10 instead became the swing hole of the tournament.
LPGA data lists the par five at 512 yards, with water guarding the front-right portion of the green. The tour’s Aon Risk Reward Challenge analysis showed how much the tee shot changes the decision. Roughly 53 percent of players reaching the fairway go for the green in two, compared with 29 percent from the rough.
Thitikul had found the left rough. She still went.
That choice mattered as much as the eagle itself. A player protecting a Sunday lead often starts seeing danger before opportunity. Thitikul saw the mistake at nine, accepted it and immediately made an aggressive decision on the next hole.
Wannasaen turned the back nine into a chase
The pressure did not come from the group beside Thitikul alone.
Chanettee Wannasaen, the 2023 Portland champion, was tearing through Columbia Edgewater elsewhere. She made nine birdies without a bogey and signed for a nine-under 63, eventually reaching 21 under.
The remarkable part was that Wannasaen did not believe she had struck the ball perfectly.
“I know that I can make putt, and when I miss the putt I can chip in,” she said after the round. Her description captured the unsettling rhythm of a player who suddenly feels as if every mistake has an answer.
That was the round unfolding behind Thitikul.
Yubol also refused to disappear. She birdied four of her first seven holes, then closed with birdies at 17 and 18 for a 67. Both players finished at 21 under, one stroke short. Official LPGA results confirmed Thitikul at 22-under 266 after her closing 64.
Thitikul initially knew little about Wannasaen’s charge. She avoids watching leaderboards when she contends, narrowing her attention to the shot in front of her. On the 15th green, her caddie finally told her she was tied.
Her response was simple: “Really?”
That small exchange gives the afternoon a more revealing texture than any generic claim about mental toughness. While Wannasaen was filling her scorecard with birdies, Thitikul had deliberately reduced the tournament to a series of individual decisions.
The final three holes demanded three different answers
By the time Thitikul reached 16, Sunday had stopped resembling the front-nine birdie rush. Now every shot carried consequence.
She needed a clutch par save at 16 and converted it. The putter that had fueled her early charge suddenly had to prevent damage rather than create separation. One hole later, the equation changed again.
At 17, Thitikul had another birdie chance and curled the putt home to regain the outright lead. She reached the 18th knowing a clean finish would force Wannasaen and Yubol to find another birdie behind her.
No miracle was required. Thitikul two-putted from off the green, then knocked in a short final putt to complete an eight-under 64. The LPGA recorded her four rounds at 68, 67, 67 and 64, good for 22 under and a one-shot victory.
Those three holes required different versions of composure. Sixteen demanded recovery. Seventeen rewarded aggression. Eighteen called for restraint.
That sequence explains why closing nerves mattered more than raw power. A golfer can overpower a par five, but no amount of clubhead speed makes those emotional shifts disappear.
Columbia Edgewater keeps raising the target
Recent winning scores show why Portland creates this kind of Sunday.
Wannasaen reached 26 under in 2023. Moriya Jutanugarn won at 22 under in 2024, and Aki Iwai followed at 24 under in 2025. Thitikul needed 22 under this year.
Those numbers form a pattern rather than a trivia list. Columbia Edgewater repeatedly asks contenders to keep scoring deep into the weekend. Par rarely functions as shelter.
The LPGA set the 2026 course at 6,541 yards, short enough by modern professional standards to produce reachable par fives and plenty of shorter approaches. Thitikul herself pointed to that reality earlier in the week, noting that players could attack several par fives and hit wedges into many greens.
Distance still helps. A longer drive can turn a difficult approach into a scoring club. Extra speed gives players more options into par fives.
Yet Portland exposes the limitation of measuring advantage through power alone.
Someone still has to convert.
A wedge from the fairway means little when a player guides it away from the flag because she sees the leaderboard in her head. A reachable par five loses its value when fear turns aggression into indecision. The closing stretch tests whether players can keep making normal swings when the circumstances no longer feel normal.
Thitikul managed that tension better than anyone.
Her routine kept the round from speeding up
Asked afterward what helps her close tournaments, Thitikul returned to one idea: routine.
She explained that players can drift toward the outcome when a trophy gets close. Thoughts jump ahead. The mind starts building scenarios around what might happen rather than what needs to happen next.
Thitikul fights that tendency by returning to the same routine she uses on ordinary shots. “Trying to stay present,” she called it.
Sunday offered several chances to abandon that process. The bogey at nine could have followed her to 10. Wannasaen’s 63 could have triggered panic once the caddie delivered the leaderboard update. Trouble at 16 could have pushed her toward caution at 17.
None of those moments changed the basic rhythm. She picked the next target and played.
Even her putting carried another layer of uncertainty. Thitikul acknowledged after winning that she had questioned her stroke during the middle of the season. Her caddie had been checking it repeatedly during practice rounds. Yet when the tournament tightened, she trusted that same stroke enough to save par at 16 and make the decisive birdie at 17.
That detail makes the finish more interesting. Confidence did not arrive because every part of her game felt perfect. She competed through the doubt.
Ten wins reveal a skill distance cannot measure
Portland delivered another marker for Thitikul.
The victory became her 10th LPGA Tour title and third win of the 2026 season. At 23, she joined a remarkably small group of players to reach double-digit LPGA victories before turning 24.
That résumé reflects extraordinary ball-striking and scoring ability, but repeated winning demands more than physical superiority.
Sometimes a player chases from behind. Other weeks she protects a lead. Occasionally, as Portland demonstrated, she has to do both within a few hours.
Thitikul began Sunday chasing. Her opening birdie barrage put her in control. The bogeys at nine and 12 complicated the round, while Wannasaen’s 63 turned the back nine into a moving target. By the closing stretch, Thitikul had gone from hunter to leader under attack.
She never needed to play flawless golf. She needed to respond faster than the mistakes accumulated.
That distinction separates a dominant statistical week from a championship Sunday.
The next Portland Classic will ask the same question
Golf will keep getting faster.
LPGA players continue to add speed, refine launch conditions and find new ways to attack par fives. Columbia Edgewater gives those tools plenty of room to matter. Another generation of players will arrive capable of hitting shorter clubs into greens that once demanded something longer.
The final examination will remain stubbornly human.
Someone will stand over a putt late Sunday knowing another player has already posted a low number. A leader will miss a fairway and have seconds to decide whether the next shot still warrants aggression. Another contender will hear a cheer through the trees and know, without seeing the leaderboard, that somebody nearby just changed the tournament.
Thitikul faced each version of that pressure in 2026. She started two shots behind. Six birdies in seven holes pushed her ahead. A bogey at nine interrupted the charge, but an eagle at 10 answered immediately. Wannasaen then fired 63, Yubol stayed close, and Thitikul reached the final three holes without room to waste a shot.
She saved par at 16, birdied 17 and finished the job at 18. Power created the opportunities. Nerve determined what she did with them.
That is where Portland strips golf down to its hardest test. Distance can put a player in position, but the closing holes demand something no launch monitor can measure.
Can you absorb the bad hole without carrying it forward?
Can you hear the charge behind you without chasing it?
And when one committed swing can decide four days of golf, can you make it feel like every other swing you have made all week?
