Wade Ormsby, Arnond Vongvanij lead in South Korea

Wade Ormsby and Arnond Vongvanij have opened up a one-shot lead at the top of the Ballatine's Championship leaderboard.

Ormsby hit six birdies on the way to a round of 67, while Vongvanij produced a solid score of 69 to remain in touch with the Australian.

The duo are closely followed by Alexander Noren, James Morrison and Jbe Kruger, while British duo Tommy Fleetwood and Stephen Gallagher are a shot further adrift on five-under-par.

Louis Oosthuizen heads a group of 16 players who are on four-under-par, with last year's winner Bernd Wiesberger down in 31st place on two-under-par.

The second round has yet to be completed after storms disrupted proceedings in South Korea.
