Jeju: South Korean Ok Tae-Hoon's bid to win for the first time in the professional game gathered momentum yesterday when he carded a third-round two-under-par 69 to take the lead in the US$1.5 million International Series Korea.
At 12 under for the Asian Tour event, he led countrymen Cho Woo-Young, one of the country's top amateurs, Seo Yo-Seop and Kim Bi-O by one shot.
Cho carded a stunning 61, Seo 67 and Kim 70 to set up an enthralling final day at the par-71 Lotte Skyhill Country Club on Jeju Island.
Thailand's Phachara Khongwatmai and Pavit Tangkamolprasert were a stroke further back, after rounds of 63 and 67 respectively.
Ok and Kim had started the third day sharing the lead, but it was the former who had the edge for much of the day reaching 14 with two to play and the prospect of a healthy lead.
However, he made bogey on 17 and 18 to give hope to the chasing pack.
"It was a disappointing finish, but I was satisfied with the round," said Ok.
"Tomorrow's conditions should be the same so I will take that into account over those two holes. The win is up to the golfing gods, but I will do my best."
Rising star Cho, aged 20, lit up the tournament with the best round of the week made up of four birdies on the front and six on the back, including five birdies in the last six holes.
It's also the lowest 18-hole score of the season on the Asian Tour, but as preferred lies are being played it could not count officially.
"I didn't play well the first two days so it's great to play well today," said Cho.
"My driver is always my best club and today I also managed to get the putter going as well. It's my best round in a tournament but not my best-ever round, I shot 12 under once in a tournament in Thailand."
He won the Korean Amateur Championship in 2020, was third in last year's Asian Pacific Amateur Championship and was ranked the country's top amateur ahead of the Asian Games, before it was postponed this year in China because of the Covid-19 pandemic.
Bi-O's attempt to win for the third time this year in Korea, one of those being in the GS Caltex Maekyung Open on the Asian Tour, remained on course despite not breaking 70 for the first time this week.
He said: "Nothing seemed to go my way today, but I tried to stay patient and capitalise on the chances I had. I did that pretty well but unfortunately on 17 I had a half-plugged lie and got up and down for bogey; I think I managed myself pretty good there."
Phachara once again putting himself in contention at the weekend -- he was joint second in last week's International Series Singapore and solo second at the International Series Thailand in March -- with a phenomenal eight birdie bogey-free round.
