Masters champion Danny Willett jumped to the front of the pack, earning a three-stroke lead after the third round at the Maybank Championship on Saturday.
Englishman Willett is now the man to beat in Kuala Lumpur following his five-under-par 67 on the penultimate day.
The winner at Augusta last year, Willett was lurking at the start of play, having teed off with just a one-shot deficit to overnight leader Bernd Wiesberger.
And as Wiesberger struggled to maintain his charge, Willett pulled clear during a near-flawless round that featured six birdies and only one bogey at the European Tour tournament.

Willett cemented his position atop the leaderboard at 16 under through 54 holes following back-to-back birdies to end the day.
American David Lipsky is Willett's nearest challenger heading into Sunday's final round.
Lipsky posted a third-round 68 to be three shots adrift, while Alexander Levy (67) is a stroke further back.
Wiesberger ended the day one over the card, having lit up the Saujana Golf and Country Club on Friday.
The Austrian was on cloud nine following his sensational second round, highlighted by nine successive birdies and 11 in total as he moved into a one-stroke lead.
But Wiesberger crashed back down to earth on the weekend, dropping four shots and only picking up three birdies.
Gregory Havret (66), Panuphol Pittayarat (66), Mike Lorenzo-Vera (70) and K.T. Kim (69) are also 11 under overall.
