Westwood followed his opening 6-under-par 66 with a 67, at one stage holding a three-shot lead at Kuala Lumpur Golf and Country Club.
Bernd Wiesberger is well positioned to cap a superb month of golf with victory in the Malaysian Open after shooting a 9-under 63 on Saturday, taking a two-shot lead going into the final round.
He moved to 17-under 199 overall at Kuala Lumpur Golf and Country Club, two strokes ahead of Spain's Alejandro Canizares, who finished his roller-coaster round eagle-birdie-bogey to card a 68.
India's Anirban Lahiri has his sights set on the U.S. Masters after winning the Malaysian Open on Sunday by firing a final round 4-under 68, finishing a stroke ahead of Austrian Bernd Wiesberger.
Anirban, who finished on 16-under 272, rolled in a 40-foot birdie putt from off the green on the 17th hole as he overcame a five-shot deficit at the start of play.
Ranked 73rd heading into this week's event at the Kuala Lumpur Golf and Country Club, Lahiri will now move into the world's top 40.
