Australia's Wade Ormsby and the Thailand duo of Kiradech Aphibarnrat and Arnond Vongvanij share the lead at 7-under par after two rounds in the weather-affected Ballantine's Championship in South Korea.
Ormsby (67) and Arnond (69) completed their rounds on Friday before being joined atop the leaderboard by Kiradech, who completed a round of 66 on Saturday morning on the Blackstone course at Icheon in suburban Seoul.
Kiradech, winner of last month's Maybank Malaysian Open title, was three shots behind the leading duo when poor light halted play on Friday, but returned on Saturday to birdie three of his closing seven holes.
''I got experience and a lot of confidence to come here this week,'' said Kiradech. ''But the weather is quite different from Malaysia.
''I was quite lucky in the second round, the wind was quite quiet. I know I can make a score and my form is good from Malaysia. My driver and putter are both great so hopefully I can stick to the game plan.''
