South Korea's Lee Soo-min put on a sizzling display with his irons to top the Maybank Championship Malaysia leaderboard on Saturday, opening a three-shot lead over closest rival Marcus Fraser after the third round.

Lee fired home nine birdies, including four in a row on the back nine, for a 7-under 64 to move to a total of 15-under 198 at Royal Selangor Golf Club.

Fraser had a 66 to be outright second, a stroke ahead of Australian compatriot and second-round leader Nathan Holman, who struggled with four birdies and a double bogey en route to a 73.
