David Gleeson has shot a two-under par 69 to remain in contention after the third round of the Bangkok Airways Open in Koh Samui, Thailand. Gleeson finds himself at seven-under for the tournament, six shots off leader Lien Lu-Sen who shot a magnificent five-under par 66 to storm clear of the field by three strokes. Trailing him is Thai duo Chinnarat Phadungsil and Thaworn Wiratchant who are both at 10-under par. Rick Kulazc continued his fine form with a 68 to be in a tie for 11th place, while Mitchell Brown shot an even-par round to be a further stroke back in a tie for 15th. Richard Moir has recovered from his poor first round to be at three-under par, equal with Adam Blyth who shot a disappointing one-over par. Neven Basic had a day to forget, shooting a disastrous 10-over par to plummet down the leaderboard.
