A magnificent 10-under third round of 62 from Callum Shinkwin cut Soomin Lee's lead to only two shots in the Shenzhen International on Saturday.
Lee took a three-shot advantage into the weekend after the first two days were disrupted by the weather at the Genzon Golf Club, with 35 players starting their second rounds on Saturday.
The South Korean moved to 14 under for the week but could only complete 11 holes in his third round, having finished his second on Friday, before play was suspended for bad light.
Lee will have 25 holes to get round on Sunday when he aims to win a first European Tour title and Shinkwin is biting at his heels after a brilliant third round - which was the best of the week.
Shinkwin played his entire second round in the morning and the Englishman did not appear to be among the challengers when he carded a second successive 71.
But the 22-year-old surged into contention with eight birdies and an eagle to move into second place, with the option of putting his feet up when the likes of Lee are finishing their third rounds on Sunday.
Lee held a commanding five-shot advantage after three holes of his third round, but Shinkwin's charge gave the leader plenty to think about.
Brandon Stone and Lee Slattery hold a share of third place, four shots off the lead with six holes still to be completed in their third rounds.
Paul Dunne, Alexander Levy and Joost Luiten will all start five shots adrift of Lee when they return to finish their third rounds on Sunday.
