JEJU ISLAND, South Korea, April 25 (UPI) -- Robert-Jan Derksen bogeyed the final four holes Saturday but leads the Ballantine's Championship at Jeju Island, South Korea, by two strokes over Pablo Martin.
The start of the round was delayed by more than three hours because of a dense fog.
The 35-year-old Dutchman had a similar lead through 36 holes, but Saturday, he shot 3-over 75 in nearly impossible windy conditions at Pinx Golf Club.
His three-round total is 6-under 210.
"I think (the course) was too tough," Derksen said. "It was unfair (and) I think it was unplayable."
Martin, a native of Malaga, Spain, shot 2-over 74, but his overall 4-under 212 total has him alone in second place.
Korea's Kyung-Nam Kang (75) and Wook-Soon Kang (77) are tied for third place, with Thailand's Thongchai Jaidee (77) at 2-under 214 -- two shots behind Martin and four back of Derksen.
France's Francois Delamontagne shot 1-under 71 and was the only golfer to break par on Saturday.
