Sophia Schubert had done everything right for three rounds at Columbia Edgewater Country Club. She had taken the lead into Sunday, played the kind of steady, unspectacular golf that so often survives a final round, and given herself a real chance at a maiden LPGA title on home soil in Oregon. Then Jeeno Thitikul reeled off five birdies in a row before most of the leaderboard had finished their coffee, and the tournament that had looked like it might come down to the last few holes was effectively over by the turn.
Thitikul’s closing 64 was eight under par, built on those five straight birdies early in the round and precisely nothing careless later in it. She finished at 22 under par for the week, one shot clear of an all-Thailand pair in Chanettee Wannasaen, who matched her with a 63 of her own, and Arpichaya Yubol, who signed for a 67. Schubert, needing something similarly bold to hold on, instead posted a 71 and slipped to solo fourth, a reminder of how quickly a 54-hole lead can evaporate against a player playing without any apparent nerves at all.
A third win that never looked in doubt for long
What made the round remarkable was not just the birdie count but how early Thitikul made her move. Portland Classic finishes have a habit of tightening on the back nine, but by the time the leading groups reached the turn, Thitikul had already built the kind of cushion that changes how a golf tournament is watched. Wannasaen’s 63 kept the pressure technically alive, and Yubol’s steady 67 meant the podium stayed distinctly Thai all afternoon, but nobody found the response that Thitikul’s start demanded.
This was Thitikul’s third LPGA Tour title of 2026, following wins at the Honda LPGA Thailand in February and the Mizuho Americas Open in May, and it places her alongside Nelly Korda as the only three-time winners on tour this season. It is also her tenth career LPGA title, achieved at 23, which makes her the eighth player in tour history to reach double figures before turning 24. Numbers like that tend to get thrown around loosely in golf, but this one sits her in genuinely rare company, and it arrives at a point in her career where the conversation about her has shifted from promising to simply excellent.
The margins that decided it
The scorecard tells its own story about where the tournament turned. Schubert had led through 54 holes and needed a big number to hold off a chasing pack that included three players inside two shots of her. Instead the pressure came from the top rather than from behind, and by the time she made the turn in the final round the tournament had already been decided somewhere back at the start of Thitikul’s card. There is a particular cruelty to losing a 54-hole lead not to a collapse of your own but to somebody else simply playing better, and Schubert’s closing 71 was a perfectly respectable round of golf that happened to be nowhere near good enough.
For Thitikul, the win is worth $300,000 from the $2 million purse and moves her closer to $20 million in career earnings, but the figures that matter more are the ones that measure consistency rather than any single week. Three wins in a season on the LPGA is a mark of a player at the peak of her powers, and doing it in three different ways, a wire-to-wire win in Thailand, a grinder in New York, and now a front-loaded blitz in Oregon, says as much about her range as any of the individual results.
What it means heading into the CP Women’s Open
The LPGA schedule allows a fortnight before the next major test at the CP Women’s Open, which gives the chasing pack time to regroup and gives Thitikul a stretch to enjoy a result that was as complete as any she has produced this year. Wannasaen and Yubol will take real encouragement from Portland too, not just the prize money but the evidence that they can go shot for shot with the best player in the world over a back nine and not be the ones who blink. Schubert, for her part, put herself in position to win an LPGA event for the first time, and those weeks tend to matter more in the long run than the box score from any single Sunday suggests.
Portland has a way of producing finishes that feel decided long before the last putt drops, and this was another one. The story of the week was not a back-nine duel but a front-nine detonation, five holes in a row that turned a tournament into a coronation before lunch.
