Seoul: South Korean amateur Ham Jeong-woo took a two-shot lead into the final round of the fog-disrupted Kolon Korea Open on Sunday.
Ham, who finished seventh in the tournament last year, completed his third-round with a birdie on the 18th for a one-over 72.
Former Open winner Y.E. Yang was tied in second place with Kim Seung-Hyuk and Chang Yi-Keun at the Woo Jeong Hills Country Club in Cheonan.
Early morning fog, which has disrupted the entire tournament, delayed the restart of the third round on Sunday morning, forcing a Monday finish on some players.
Ham played the most assured golf amongst the leaders when the third round eventually re-started with two birdies and a lone bogey in his remaining 10 holes for a 72 and a total of three-under 210.
Yang, a two-time Korea Open winner who is looking for a confidence-boosting victory after a poor season, was ahead by a shot when play was stopped on Saturday evening but failed to carry his form into Sunday.
He had a double-bogey at the 13th before picking up a shot at the 15th. The 2009 PGA Championship winner fell two behind Ham when he bogeyed the final hole.
