(UPDATE) JOHN Rey Oro brushed off an early threat from twin brother John Paul with a scorching backside start, turning a narrow lead into a commanding six-stroke victory with an even-par 70 in the premier category of the ICTSI JPGT Iloilo Visayas Series on Thursday in Iloilo.

Rhiena Mae Sinfuego matched John Rey's wire-to-wire triumph with an even more emphatic win in the girls' 16-18 division of the first of three tournaments in the region organized by Pilipinas Golf Tournaments Inc. She carded an 88, amassing a four-day total of 356 at the Iloilo Golf Club.

John Rey, 17, turned up the heat on the back nine of the challenging layout, transforming a two-stroke edge into a five-shot advantage with back-to-back birdies from No. 10. In contrast, John Paul faltered with a bogey on the 11th and John Rey's consistency shone through as he sustained his momentum, adding a chip-in birdie on the difficult par-3 13th, which John Paul bogeyed from five feet.

This solid performance set the stage for John Rey's unassailable claim to the boys' 16-18 trophy with a 72-hole total of 296.

"After I birdied numbers 10 and 11, I gained momentum and everything just flowed from there. I also thanked God for giving me this opportunity," said John Rey, celebrating his sixth victory and eagerly anticipating the upcoming legs of the JPGT Visayas swing in Bacolod, their home turf.

John Paul actually threatened within one with a birdie on the seventh but conceded the stroke on the next hole after missing green. He also failed to match John Rey's solid backside start although he closed out with two birdies in the last three holes to save a 74 and a 302, completing the Oros' domination of the centerpiece division of the four-category series. Eddie Gonzales Jr. placed third at 318 after an 84.

Sinfuego earlier showcased her dominance over Necky Tortosa, who struggled with a 107, finishing at 423. Blessy Solinap recorded a 114, concluding her campaign in the ICTSI-sponsored series with a 470.
