form Frenchman Victor Dubuisson fired a four-under 68 to take the first-round lead at the Ballantine's Championship as swirling winds made scoring tough in Seoul Thursday. The 22-year-old compiled eight birdies in a mixed round at the $2.2 million European and Asian Tour event to move two strokes clear of a group of five players including former Ryder Cup player Paul Casey. Dubuisson, who finished tied fourth at last week's China Open, took 26 putts Thursday as he chased his first professional title. Dubuisson's card was marred by a double-bogey six on the fourth and bogeys on the 10th and 16th but he did not let those blemishes upset him. “On the third hole the wind was from the left and so on the fourth tee I thought the wind was going to be left to right but the wind was turning all the time. It turned right to left and it went into the water,” the Frenchman said of his tee shot. “I was not really upset after that because I didn't hit a bad shot. I did my best to get my concentration back and I made two birdies with good putts on five and six.” World number 11 Adam Scott of Australia, the highest-ranked player in the field, was three behind Dubuisson on 71 after making four birdies in a chilly early start. Jung Ji-ho was leading the South Korean challenge on 70 alongside Casey, Scot Richie Ramsay, Englishman Mark Foster and Welshman Jamie Donaldson. Former US PGA champion Yang Yong-eun (74), struggled in the difficult conditions along with England's Ian Poulter (75) and Asian Tour order of merit leader Jbe Kruger (79) of South Africa.
