Felipe Aguilar opened up a one-shot lead on day two of the Volvo China Open before play was suspended due to the threat of lightning at Topwin Golf and Country Club.
The Chilean was one of the morning starters and managed to get to 11 under after an excellent round of 65, but the thunderclouds came over at 3.50pm with the earliest of the afternoon starters still having three holes to play.
The second round was due to resume at 6.45am on Saturday morning, with play in round three not set to get under way until 10am.
Aguilar's unblemished 65 had moved him ahead of Alex Noren and Bernd Wiesberger, with Lucas Bjerregaard, Tyrrell Hatton and Tae-hoon Kim all in the clubhouse at nine under.
First round leader Hennie Otto was also at nine under with four holes to play upon the resumption, alongside Marcel Siem who was five under for the day with five to play.
Aguilar made it to the weekend in Shenzhen last week after missing six straight cuts and he admitted his body has been feeling the strain after taking part in an ironman triathlon over the winter.
"I was pretty unstable at the start of the year," he said. "I missed several cuts by one or two shots and I wasn't putting very well, missing shots that I usually don't. I guess now I believe my doctors when they said I would struggle to recover my fitness from doing an ironman competition.
"They said I would struggle for about two months afterwards and I actually did because it's such fine margins in this sport. I haven't done much exercise in recuperating my body, but I have been doing a lot of work lately so hopefully this will do it."
Aguilar turned in 34 after gains on the fourth and eighth but came to life after the turn as he picked up further shots on the tenth, 11th, 14th, 16th and 18th.
"I played quite solid today, I don't think I missed one green," he added.
I played quite consistently throughout my first two rounds so I'm quite happy. It's been a tough start to the year so hopefully this will be a turnaround for me - Felipe Aguilar
"I struggled with a couple of bad shots but I ended up being in the right spots on the right greens."
Swede Noren had an unblemished second consecutive 67, recording birdies on the 13th, 15th, first, third and sixth, while Austria's Wiesberger turned in level par 36 after starting on the tenth and back-to-back birdies on the fifth and sixth added to a gain on the first in his 69.
South Korean Kim recorded the second hole-in-one of the week when he holed from 177 yards with a seven iron on the 13th, adding to seven birdies and a bogey in a 64.
Dane Bjerregaard was bogey-free as he signed for a 67, with England's Hatton registering two bogeys and seven birdies on his way to the same score.
German Maximillian Kieffer recorded a 66 to sit at eight under, with home favourite Li Haotong at the same mark after a 67.
Gary Boyd, Nicolas Colsaerts, Jorge Campillo, Alexander Levy and Thorbjørn Olesen were then all a further shot back in the clubhouse, alongside Grégory Bourdy, Richard Bland, Peter Hanson, Grégory Havret and Fabrizo Zanotti who were all around the turn when the horn sounded.
