Joint overnight leader Terry Pilkadaris had one of those rounds he would prefer to forget at the Maekyung Open in Seoul on Friday. The Australian carded a three-over round of 75 to drop to equal 12th at the One Asia event, trailing Korea&aposs Hyung-sung Kim by five shots. Hyung-sung fired a five-under-par 67 to grab a one shot lead after the second round. The Japan Tour regular had six birdies and a bogey to stand at 10 under. Kim Gi-whan also shot 67 to finish alone in second place, while Kim Dae-sub is a stroke further behind after posting a round of 66. The course once again lived up to its reputation as a graveyard for foreigners, with Pilkadaris the best of the non-Koreans. Cho Min-gyu (73), who shared the first round lead, also remains in the hunt at seven under. Australian Jake Higginbottom (71) who turned pro in November just two days after winning the BMW New Zealand Open, will also start the weekend at four under, alongside countryman Matt Griffin (73) and New Zealander Mark Brown (70).
