Thailand&aposs Chawalit Plaphol has continued his impressive form to take a one stroke lead going into the final round of the Vietnam Masters at the Hanoi Phoenix Golf Resort. The Australian contingent struggled on day three, with David Gleeson doing the best at four-under par in a tie for 13th. Jason King is the only other Australian still under par for the tournament, although Adam Le Vesconte shot a solid two-under to be even with the card. Mitchell Brown carded a four-over 76, while Neven Basic had a day he&aposd rather forget, taking 10 strokes to finish the par five fourth on his way to a disappointing 12-over par round of 84. Simon Griffiths is keeping up the pressure on Plaphol, as he lies just one stroke behind the leader. But the Thai player hasn&apost shot a bogey 49 holes, so catching him will be a difficult task. A group of four players are in a tie for third position four shots off the pace, but it seems unlikely that they will challenge the leaders, as the course is proving to be very hard with only five golfers – in a field of 66 – carding a score under 70 in the third round.
