DAVAO CITY — Johanna Blair Uyking showed nerves of steel and a touch of magic on the greens Friday, pulling off two clutch birdies to fend off Nicole Gaisano Gan, 3 and 1, and punch her ticket to the semifinals of the Philippine Amateur Open Championship at Apo Golf and Country Club.

The duel was tight all afternoon, and with the match all square through 14 holes, Gan looked poised to finally seize control. Her approach shot landed just four feet from the pin — about as close to a sure birdie as it gets.

But Uyking had other plans. Standing 30 feet away, she rolled in a stunning birdie putt that left the small gallery gasping, tilting the momentum in her favor.

Visibly rattled, Gan couldn’t answer back, missing her short birdie putt to give up the hole.

On the par-4 16th, both players safely reached the green in regulation, but Uyking once again stole the spotlight — this time draining another long birdie putt to widen the gap.

By the 17th, the pressure had clearly shifted.

Gan’s approach found the bunker while Uyking was safely on in two. Before she could even line up her birdie try, Gan extended her hand in concession.

“I was surprised,” Uyking admitted with a smile. “I thought she still had a chance.”

It was a tough loss for Gan, who had actually gone 2-up early before unraveling with three straight three-putts that handed the momentum back to Uyking.

Uyking now sets up a semifinal showdown with Mona Sarines, who cruised past 11-year-old Athena Batican, 4&3.

On the other side of the bracket, top seed Lisa Sarines booked her spot in the final four after outlasting Merry Rose Wacan on the 25th, while Crista Minoza ousted Precious Zaragosa, also 4&3.

In a marathon match that extended to seven extra holes, Lisa Sarines picked up the win after Wacan sent her tee shot to the water on the seventh hole.

The men battled through two grueling 18-hole rounds on Friday, sealing the semifinal lineup in a tournament filled with tension and thrilling moments.

Advancing to the next stage were 12-year-old sensation Vito Sarines, top seed Perry Josef Bucay, relentless Bobe Salahog, and hometown favorite AJ Wacan.

Sarines’ victory came down to a nail-biting finish against Junior Golf Foundation of the Philippines president Oliver Gan.

With the pressure mounting, the young prodigy produced a spectacular escape from under the trees and sank a nerve-wracking 20-foot birdie putt on the final hole to clinch the win.

Gan, a 42-year-old businessman who rarely competes outside club events, expressed pride despite the narrow loss.

“It’s an honor to reach the quarterfinals of such a prestigious tournament,” he said. “I’m not sure if I can do this again next year.”

Earlier, Sarines dispatched Alexander Bisera, 4&3, while Gan advanced via walkover against Santi Laurel in the Round of 16.

Meanwhile, Bucay fought off tough challenges, posting 1-up victories over Billy Vidal in the Last 16 and Alexis Nailga in the quarterfinals.

Bobe Salahog edged senior standout Don Breganza in the Last 16 before ousting Zach Villaroman, also 1-up, in the quarters.

AJ Wacan stormed out of the gates, winning the first four holes en route to a commanding 4&3 victory over Cagayan de Oro’s Apollo Batican.

The stage is set for Saturday’s men’s semifinals: Sarines will face Salahog in a clash of skill and youthful ambition, while Bucay takes on Wacan in what promises to be a fierce battle for a spot in the finals.
