MANILA (AFP) - Thailand's Sutijet Kooratanapisan fired a three-under 69 to seize the lead at the Manila Masters golf tournament on Saturday, with teenage sensation Phachara Khongwatmai in hot pursuit.

After a consistent round in windy conditions highlighted by an eagle on the fourth hole, the 29-year-old vowed to be positive as he chased his maiden Asian Tour title at the Manila Southwoods Golf and Country Club on Sunday.

"My plan tomorrow is to attack the fairways and greens. I'll be aggressive. I don't want to think too much as that will give me added pressure," said Sutijet, who at 16 under sits two shots clear of compatriot Phachara.

Phachara also shot a 69 and, with the confidence of youth, gave himself a strong chance of what would be a stunning win.

"I'm only two shots back and I still can catch up," said Phachara, who has lit up the Asian Tour with three top-five finishes in his past four tournaments.

After an impressive 65 the day before that had him atop the leader board after two rounds, India's Jyoti Randhawa battled all day to card a two-over 74 and fall back to an equal share of third place.

Alongside him on 13 under are countryman S.S.P. Chawrasia, who mixed his card with three bogeys and four birdies for a 71, South Africa's Jbe Kruger and Australian Terry Pilkadaris.
