BAGUIO – A thick blanket of fog rolled in and out of Pinewoods Golf and Country Club on opening day, repeatedly halting play and adding an eerie unpredictability to an already demanding layout.

Through the shifting visibility and mounting pressure, 17-year-old Tiffany Lee stayed composed just long enough – and struck just boldly enough – to seize control of the ICTSI Pinewoods Challenge.

Lee closed with a three-under 69, highlighted by a blistering late stretch that flipped the script on a volatile round, giving her a two-stroke cushion over Chanelle Avaricio after 18 holes of the 54-hole, P1 million championship.

“It’s a very tough course, honestly. You need a lot of accuracy and a good short game,” said Lee, summing up a day where precision mattered as much as patience – especially with fog delays breaking rhythm and testing focus throughout the field.

For Lee, the round was anything but linear. She opened with a roller-coaster front nine, mixing four birdies with two bogeys and a double bogey, made even more difficult by intermittent stoppages as fog swept across the course. Just when momentum seemed uncertain, she reignited her round with a decisive four-birdie burst starting on No. 14.

That late surge transformed what had been a crowded leaderboard into a clearer statement of intent.

“I was focusing on hitting more confidently, especially on narrow fairways and small openings into the greens,” she said. “I tried to commit fully to my shots so I could execute properly.”

Even so, a closing bogey prevented her from stretching the lead further – but not from walking off with the outright advantage.

“The greens are hard and fast, very difficult to control,” added Lee. “I just had to work through it the best I could.”

Behind her, Avaricio showed flashes of command but could not sustain it. She opened with an eagle-aided 32 and briefly threatened to run away with the round, only to stumble on the back nine with three bogeys against a birdie for a 71.

“My tee shots were pretty good, but I struggled around the greens and my putting was a little off,” said Avaricio, who admitted the course setup and slick surfaces punished small errors. “I need to do better on my putting.”

She also credited insights from Monday’s pro-am round for helping her navigate the tricky conditions, though the late-round wobble proved costly.

“I was able to read some notes from the pro-am – it helped a lot,” she added.

Just behind the lead pair, momentum shifted repeatedly across a tightly packed leaderboard.

Mafy Singson stayed in contention for much of the round but faded late with bogeys on Nos. 16 and 18, finishing with a 72, while Monica Mandario endured one of the day’s sharpest reversals – racing to a four-under start, including an eagle on No. 14, before a back-nine collapse featuring multiple bogeys and a double bogey dropped her to a 73.

Sharing fourth place was Harmie Constantino, the Caliraya Springs standout, who stayed within striking distance despite the shifting conditions.

Further back, Daniella Uy, Gretchen Villacencio, and Seoyun Kim matched 74s, while Princess Superal slipped to a 75. Yvon Bisera posted a 76 alongside Chihiro Ikeda in a congested chase pack.
