Defending champion Graeme McDowell has endured a nightmare opening round at the Ballantine's Championship in South Korea. The Portrush golfer carded a 76 to finish four over par and 11 shots off the lead, which is jointly held by Australian Mark Brown and Spain's Gonzalo Fernandez-Castano. Damien McGrane is best of the Irish competitors on three under par, with Peter Lawrie on two under and Paul McGinley on one over.
