Former Masters champion Charl Schwartzel and Wu Ashun of China were the clubhouse leaders in the Malaysian Open after the second round was suspended because of darkness on Friday.
Schwartzel and Wu scored 4-under-par 68s to lie 9 under overall halfway through the European and Asian Tours event at Kuala Lumpur Golf and Country Club.
But 75 players, exactly half of the remaining field, were unable to complete or even start the round, including scoreboard leader Kiradech Aphibarnrat of Thailand, who was at 10 under through nine holes.

They in turn were one shot ahead of a group of five at 5 under, including Rafa Cabrera-Bello, who posted a best-of-the-day 67 after an opening par round.
