STOCKHOLM – K.J. Choi took a one-shot lead at the halway point of the Scandinavian Masters after shooting a 5-under 67 in the second round Friday.
Choi mixed six birdies and an eagle with three bogeys to reach a 9-under total of 135, one stroke ahead of Richard Johnson of Sweden, who carded a 66.
British Open champion Louis Oosthuizen was one of the overnight leaders but he slipped to third after a round of 70, leaving him two strokes behind Choi and level with Rafa Echenique of Argentina.
Teeing off early in windy conditions at Bro Hof Slott, Oosthuizen had a double bogey at the 150-yard, par-3 17th after landing in the water.
The South African collected three birdies and another bogey on his first nine holes, for a par 36, which was four shots off his performance on Thursday.
“I didn’t putt as well today, I missed a few,” Oosthuizen said. “I’ll have a nice rest this afternoon. It should be great tomorrow.”
Choi had an impressive start with an eagle on the 15th, as well as birdies at the 13th, 16th and 17th, for a 5-under 31 on his first nine.
“From the first hole I felt that my shot was there, my rhythm was good. I was hitting my driver, my irons very well,” Choi said. “My putting was going good, too, so I felt a lot of confidence going into the first few holes.”
Johnson had a bogey-free round in front of his home crowd put him 8 under after 36 holes.
Dustin Johnson of the United States, who was tied with Richard Green and Oosthuizen after the first round, lost ground on the leaders after a round of 73, putting him at 4 under.
Green was three shots off the lead after a 71, including consecutive bogeys at holes 4 and 5.
