Tom McKibbin and Ding Wenyi were tied at the top of the leaderboard when the second round of the Singapore Classic was suspended due to fading light on Friday.
First-round leader McKibbin had mixed five birdies with two bogeys on day two before play had to be halted for an hour due to flooded greens as he played the 18th.
When the action resumed at 18:20 local time, the Northern Irishman closed his round with a par to sign for a 69 and head into the weekend on 11 under.
He was soon joined at the summit by 18-year-old Chinese amateur Ding, who carded two eagles, two birdies and a bogey in his first 14 holes before the daylight ran out.
Ding will return to complete his second round at 08:15 local time on Saturday.
German Marcel Schneider and England’s Andy Sullivan were the co-leaders’ nearest challengers on 10 under.
Zander Lombard is the best-placed South African (T23) after rounds of 67 and 71 took him to six under.
Ockie Strydom is a further shot behind after a second-round 68.
