Soomin Lee has gone three shots clear with one round to play at the inaugural Maybank Championship Malaysia thanks to a third round of 64 in Kuala Lumpur.
The South Korean's seven-under-par score on day three at Royal Sengalor Golf Club saw him reach 15-under and climb to the top of the leaderboard as halfway pacesetter Nathan Holman could only manage two-over 73 to drop four back.
Holman's fellow Australian Marcus Fraser is alone in second place on 12-under thanks to a third-round 66.
World number 13 Danny Willett (-6) fell off the pace with a 73, while Finland's Mikko Ilonen matched Lee's 64 to rise up to joint-seventh on nine-under.
