American Rickie Fowler is finally is sight of a first pro career win after establishing a new course record to lead by four shots heading to the final round of the Kolon Korea Open.

Fowler, 20 emerged from a fog delay to record a sizzling eight-under par 63 to move to 13-under par in glorious conditions on the Woo Jeong Hills course.

The American, who will be decked out in all orange for the last round, had been among five players tied for the lead after two rounds.

But he now leads Yang by two after the defending champion and 2009 PGA Championship winner carded a third round 67. 

Big disappointment was the effort of reigning U.S. Open champion, Rory McIlroy who crashed from a tie for the lead after 36 holes and back into a share of fourth place after signing for a 73 and a four-under par tally.

Fowler is on a first visit to Korean and the World No. 36 could not be happier as he looks set to win for a first time as a pro.
 
“I had a good round and I can’t complain with a 63,” said 22-year-old Fowler.
 
“Going into the round I wanted to drive the ball well and make some putts, and I was able to do that and that puts me in a good position. My goals were to drive well and putt well, but my overall game was also good.”
 
The 2010 U.S. PGA Tour Rookie of the Year hit the ground running after reaching the turn in a flawless five-under-par before adding three further gains on the way home, while Fowler ensured his perfect round with a chip-in save at the par three 16th.
 
“I think I can win,” he added.

“I feel good about my game and I’m in a great position, which is right where I wanted to be coming into the week.”
 
But after overcoming a 10 shot deficit last year to claim a second Kolon Korea Open title, world number 43 Yang is certainly not out of contention after posting six birdies to the delight of an enthusiastic home support two hours south of Seoul.
 
“After the fog delay the weather was good and it was a good round,” said the 39-year-old 2009 PGA Championship winner.
 
“Rickie and I had a good battle at the top of the leaderboard and I am satisfied with the round.
 
“I made bogeys on the par fours after I hit bad tee shots, but if I can drive well in the final round, I have a chance to get a low score.”
 
McIlroy started well with a two birdies but the 22-year-old then dropped six shots in eight holes around the turn, including an eventful 11th hole bogey, before finishing with back-to-back birdies to improve to three-under-par overall.
 
“I had a good finish, but it was not my best day,” said McIlroy.

“I played quite nicely over the first few holes, but the pin positions were very tricky. I was two under through eight holes and I felt pretty good, but I missed a little putt on nine which threw me a little.
 
“I played 10 and 11 pretty well, but I hit a tee shot on 12 which I have not hit that wide all week. And after I hit my first ball out of bounds, I then hit my second in the rough and as I was taking a practice swing I hit another ball which I didn’t see and at first the rules official said that I had played a wrong ball.
 
“I had no intention of hitting it, but I got it up and down with the other ball and thought I had made seven, but the rules official then said it was OK and I actually made five. That got into my head a little and I lost it a bit on the back nine and I got on a bit of a bad run, but I then played the final two holes a lot better after two good drives.”
