Americans Ryan Moore and Gary Woodland will return to Kuala Lumpur Golf and Country Club on Monday morning to contest a play-off for the weather-delayed CIMB Classic.
Two suspensions due to the threat of lightning – the first lasting just over three hours – meant floodlights were blazing on the 18th hole in this US PGA Tour event when Woodland missed from nine feet for birdie to win in regulation.
Moore scrambled a par five after a superb pitch to three feet to ensure the pair finished tied on 14-under-par, one shot ahead of Thailand's Kiradech Aphibarnrat – who won the European Tour's Malaysian Open on the same course in March – and Chris Stroud.
Tournament officials then announced it was too dark to begin the play-off, with play scheduled to resume at 7:30am local time on Monday.
"It was tough, there were too many shadows but we will get a good night's sleep and come back tomorrow," Woodland said after a closing 69.
Asked about his birdie putt on the last, he added: "I hit a good putt, hit it where I wanted it, just broke more than I thought.
"I played good today and we are excited about tomorrow. I am driving the ball well which helps when the course is playing wet and long like this.
"I got myself in a bit of trouble down 18 and fortunately was able to scramble and make a par and still be in this thing" - Ryan Moore
Moore had looked set to bogey the last after finding rough off the tee and with his second shot, but salvaged par to card a round of 70.
"I got myself in a bit of trouble down 18 and fortunately was able to scramble and make a par and still be in this thing," he said.
Moore admitted he felt "less than fantastic" over his crucial putt, but added: "Any time you face a putt you have to make it makes it that much harder, but you just try and step up and hit it like you normally do."
Stroud came close to chipping in on the last for a birdie to join the play-off, while Aphibarnrat was left to rue a bogey on the 10th and his inability to find a birdie on the last eight holes.
