English golfer Lee Westwood had his four-shot lead trimmed to one on Saturday after a bogey at the final hole on day three of the Malaysian Open.

Westwood had a third-round 71 for a total of 14-under-par 202 to be only one stroke ahead of compatriot Andy Sullivan, who had a 66 in pursuit of his first tour title.

They appear set to fight it out for the crown on Sunday, as there is a three-shot gap between Sullivan and third-placed Frenchman Julien Quesne, who had a three-under round of 69.

Westwood two-putted the final green at Kuala Lumpur Country Club for bogey after having to play his approach shot from the slope of a fairway bunker.

Wade Ormsby is the best-placed Australian on 210 after a third-round 69 – eight shots behind Westwood.

Fellow Australian Scott Hend is two strokes behind Ormsby after firing an even-par 72 in the third round.

Westwood, who turns 41 next week, won the Malaysian Open in 1997 and is looking for a repeat to end a near two-year winless drought. For a third day in a row, he birdied the opening hole before dropping a shot with a three-putt bogey at the second.

He added birdies at the fifth – also for a third day in succession – and at the par-3 12th before two-putting the last hole for bogey.

“It was tricky out there and I didn’t play as well as I did the first two days and there was some tough flags out there,” Westwood said. “I got a couple of bad breaks out there today but I am leading with a day to play, so I am quite happy with that.”

Italy’s Matteo Manassero celebrated his 21st birthday with his best round of the tournament, a 67 to sit in a tie for 14th at six-under.

Defending champion Kiradech Aphibarnrat was forced to pull out ahead of the third round because of inflammation of his tonsils.

There was no sign of the hornets that attacked Pablo Larrazabal on the 14th hole during Friday’s second round, forcing the Spaniard to jump into a water hazard. Larrazabal shot a 70 to sit tied for 23rd at four-under.
