Ashley Chesters carded a 5-under 67 to take the lead at 9-under in the second round of the European Open, which was suspended due to failing light on Friday.
The 27-year-old, who also had a bogey-free round on the opening day, was tied with fellow Englishman Jordan Smith at 8-under when play was halted due to a heavy downpour.
Smith missed his last 11-foot par putt on the ninth hole when play resumed almost four hours later, while Chesters shot his fifth birdie to take sole leadership.
Siddikur Rahman carded a 66 and was one stroke behind Chesters, along with defending champion Alexander Levy, Stuart Manley, and Richard McEvoy, who all have to complete their second rounds on Saturday morning.
Jens Fahrbring was level with Smith at 7-under.
