Little-known Thai Kiradech Aphibarnrat edged ahead of Spain's Alejandro Canizares as the Maybank Malaysian Open was once again postponed due to bad weather.
Aphibarnrat managed a perfectly timed eagle to take the lead on nine-under after 14 holes of the second round, before the murky weather finished off any hopes of completing play.
"I'm very happy with that eagle," said Kiradech. "It wasn't quite dark. I wanted to continue and chipped in. Finishing with an eagle was great.
"I wasn't playing well before. I changed my clubs before the Asian Tour International and didn't feel comfortable with it. I changed another set of clubs before coming to this tournament," he added.
"This time is much different because this tournament is bigger with a lot of top players, but I need to keep going."
Soren Hansen and Angelo Que had set the early pace before Canizares made his move, taking the clubhouse lead on eight-under.
Asian number one Thongchai Jaidee only managed to play 16 holes of his second round and ended up three shots off the pace, while Peter Lawrie was the best of the Irish and remains in contention on three-under-par, six shots off Kiradech.
