Kim takes St Omer lead
The South Korean had shared top spot with Englishmen Adam Gee and Simon Wakefield on Thursday but his rivals both carded one-over rounds of 72 to drop into a tie for third.
Kim, starting at the 10th, had eight successive pars before he birdied the 18th and also the eighth and nine – dropping his solitary shot at the par-three second, took advantage to move to six under as conditions became tougher later in the day.
