Approach accuracy comes alive at the Portland Classic when one flushed iron can erase a mistake before the crowd has finished reacting. Jeeno Thitikul offered the perfect example on Sunday at Columbia Edgewater Country Club.
She had just bogeyed the ninth, and her charge could have stalled there. Instead, Thitikul walked to the 512-yard par-5 10th needing an answer. Her drive finished in the left rough, hardly the textbook setup for an aggressive second shot. She attacked anyway. A beautifully struck approach found the green, and the eagle putt dropped.
The momentum snapped back in an instant. That sequence captured what this tournament demands. Columbia Edgewater gives players birdies, but contenders still have to manufacture them.
Finding the green is only the beginning. The real advantage comes from controlling carry, trajectory and landing position well enough to create putts that should be made. When the winning number regularly dives beyond 20-under, approach accuracy stops being a luxury. It becomes survival.
Columbia Edgewater turns birdies into a requirement
A quick glance at recent Portland Classic champions shows just how aggressive the scoring has become. Across the last four editions, from 2023 through 2026, the winning score has averaged 23.5-under par. Chanettee Wannasaen reached 26-under in 2023, while the next three champions finished at 22-under, 24-under and 22-under.
Those numbers change the psychology of a round. A safe shot to the middle of a green may look perfectly acceptable during a major championship. At Columbia Edgewater, that same shot can feel like a missed opportunity when another player has wedged inside eight feet.
The course does not overwhelm players with sheer length. Instead, it asks them to keep attacking manageable targets while avoiding the wrong misses. Its greens average roughly 5,500 square feet, and the course features 54 bunkers. Poa annua has traditionally covered the putting surfaces, adding another layer to distance and spin control.
That combination rewards a specific type of aggression. Players do not need to fire blindly at every flag. They need enough control to identify which pins deserve an attack and which require a safer landing spot.
Approach accuracy matters because it lets a contender stay aggressive without turning every birdie attempt into a gamble.
Thitikul showed what the winning formula looks like
Thitikul began the final round two shots behind 54-hole leader Sophia Schubert. She did not spend Sunday waiting for the tournament to come toward her.
Birdies started immediately. Thitikul made one at the first, then ripped off five consecutive birdies from Nos. 3 through 7. Even with her bogey at nine, she reached the turn in 31.
The field suddenly had a different problem. The world-class player chasing from behind was now forcing everyone else to chase her.
The shot that changed Sunday
Then came No. 10.
The LPGA lists the hole at 512 yards, making it a clear scoring opportunity for players who can position the ball well enough to attack in two. Thitikul knew that. After the round, she explained that reaching the fairway would normally give her a chance to find the green with her second shot. Instead, she missed left into the rough.
That is where the sequence becomes more revealing. Her tee shot did not create the perfect angle. Her approach rescued an imperfect one.
Thitikul produced the shot she needed from the rough, reached the green and made eagle. She later described the moment as a major momentum change after the bogey at nine.
Elite approach accuracy does not mean hitting every iron from the center of the fairway. Sometimes it means controlling a difficult lie well enough to keep attacking when the ideal plan has already disappeared.
That distinction mattered on Sunday.
At Portland, greens in regulation only tell half the story
Golf statistics can make two approach shots look identical. Player A hits the green and finishes 38 feet away. Player B hits the same green and leaves eight feet.
Both record a green in regulation. Only one has created a serious birdie opportunity.
That gap explains why approach accuracy requires a deeper look than raw GIR percentages. Proximity matters. So does the angle of the next putt. Landing a ball beneath the hole can matter more than simply finding the correct patch of grass.
KPMG Performance Insights provided a striking example before the 2025 Portland Classic. Haeran Ryu entered that week leading the LPGA Tour in strokes gained approach at +1.39 per round while also leading in greens in regulation at 76.9 percent.
Her opening round made the numbers tangible. From 150 to 175 yards, Ryu’s season-long average proximity measured 27 feet, one inch, the best mark among qualified LPGA players at the time. At Columbia Edgewater that Thursday, her four approaches from that range averaged just 12 feet, three inches, with every shot finishing inside 16 feet.
That is what high-level iron play looks like in practical terms. Not simply green after green, but chance after chance.
Precision matters because putting has limits
A player can steal a few birdies with the putter. Winning an event near 24-under requires something more sustainable.
Nobody wants to spend four rounds asking a putter to rescue 30-foot opportunities. Instead, elite approach accuracy reduces the amount of extraordinary putting required. A seven-footer still needs to be made, but repeatedly creating seven-footers puts far less pressure on the stroke than living outside 25 feet.
Portland’s recent scoring history makes that distinction especially important. Thitikul shot rounds of 68, 67, 67 and 64 to finish at 22-under in 2026. Arpichaya Yubol and Chanettee Wannasaen finished only one stroke behind her. Wannasaen even fired a final-round 63.
There was almost nowhere to hide. A routine par could cost ground. Two pars could feel expensive. Three loose approaches might force a player to spend the next hour trying to recover birdies she should already have made.
That environment turns proximity into pressure. Put an iron to six feet and the opponent sees it. Miss 35 feet away and she sees that too.
The tee shot and approach cannot be separated
Thitikul’s second shot at No. 10 also reveals something more complicated about approach accuracy. Iron play begins before the iron leaves the bag.
A drive in the correct section of the fairway gives a player a cleaner lie, predictable spin and a better view of the green. Miss into rough, and the calculation changes. Grass can reduce control between the clubface and ball. A back pin suddenly looks less inviting.
Thitikul beat that problem at 10. She should not have needed to.
Over four rounds, repeating that kind of recovery becomes a dangerous strategy. Great players can produce spectacular shots from imperfect positions, but the percentage play remains simple: create better angles and make the approach easier.
That is why driving accuracy and iron play remain so tightly connected at Columbia Edgewater. Players do not need every fairway. They need enough of them.
From there, approach accuracy determines whether a useful tee shot becomes six feet for birdie or 35 feet for a hopeful two-putt.
Sunday pressure changes the target
Technical precision becomes harder when the leaderboard starts moving. Thitikul knew exactly what kind of Sunday she faced. Her own description after the win stripped the strategy down to its simplest form: she needed birdies.
That sounds obvious until a player actually has to execute it. A tucked flag suddenly looks smaller. The rough looks thicker. A seven-iron that felt automatic on Thursday begins carrying the weight of a season.
Meanwhile, another roar rises from somewhere across the property. Wannasaen’s 63 made that pressure real. Yubol’s 67 kept her within one. Thitikul could not protect a comfortable cushion because no comfortable cushion existed.
She had to continue creating opportunities.
That is where approach accuracy becomes psychological as well as technical. Confidence allows a player to commit fully to the target. Doubt produces defensive swings, safer lines and fewer realistic birdie chances.
At Columbia Edgewater, playing safe with too many irons can become its own form of danger.
The next champion will need to keep firing
The Portland Classic has developed a clear identity. Birdies come in clusters, leads disappear quickly, and a player can shoot 67 and still feel as though she left something behind.
That makes approach accuracy one of the clearest separators at Columbia Edgewater.
The driver still matters. So does putting. No champion reaches the low 20s under par without both. Yet the approach shot connects everything, turning position into opportunity and power into eagle chances on the par 5s.
Thitikul’s Sunday at No. 10 gave the tournament its cleanest illustration. She had just made bogey, and her drive missed the fairway. Momentum looked ready to slip away.
Then came one precise strike. The ball found the green, the eagle followed, and the championship changed shape.
That is why approach accuracy remains such a powerful predictor at the Portland Classic. On a course where 20-under may only get a player into contention, avoiding mistakes will never be enough.
The champion has to keep creating birdie chances. When Sunday tightens around the final few holes, the tournament may come down to one target and one iron swing that has to be exactly right.
