Sylvania, OH (My Sportsbook) - Korea's Eunjung Yi fired a 10-under 61 and took the third-round lead Saturday at the Jamie Farr Owens Corning Classic.

Yi holed out from the fairway for an eagle at No. 10 and collected eight birdies without dropping a shot, carding her best score on the LPGA Tour by five shots.

The 21-year-old Yi moved to 18-under 195 and will carry a four-shot lead over fellow Korean Song-Hee Kim (64) and major champion Morgan Pressel (67) into Sunday's final round.

Mikaela Parmlid shot a 62 to lead seven players who were two strokes further back at 12-under 201.

Amazingly, Yi's 61 was not a course record on the par-71 Highland Meadows layout. Paula Creamer, who withdrew on Thursday, fired a 60 in the first round last year on the way to winning the tournament.

Annika Sorenstam has the only 59 in LPGA Tour history, a mark Yi could have matched if she holed her final approach shot Saturday into the 18th green for eagle.

Instead, Yi knocked it to four feet. But she missed the birdie putt -- it curled around the left side of the cup -- and a chance to tie Creamer's mark of 60.

It was only her ninth par of the round -- the rest of her scorecard was filled with red numbers.

Yi was four-under par for the round when she reached the 10th hole, where she holed a 110-yard shot with her pitching-wedge for eagle. She notched birdie putts of eight and six feet at the 12th and 13th holes, respectively. Then, closing in on the course record, she drained a 12-footer for birdie at the 16th and a 13-footer for birdie at the 17th.

Focused on her round and not the scoreboard, Yi said she wasn't aware of how low she was going. She didn't even know she had the lead until a member of the media asked her about it afterward.

"I'm the leader?" asked Yi, whose 195 tied the tournament's 54-hole scoring record. "I didn't see the scoreboard. I'm very excited. I hope to play well tomorrow."

Before Saturday, Yi had never scored better than a 66, which she posted in the second round of the 54-hole NW Arkansas Championship last July.

"I think on this course I can make very good shots, so hopefully (I make) more birdies tomorrow," said Yi. "I just have to keep focused."

Pressel, tied with Kim at 14-under 199, collected four birdies in a five-hole stretch Saturday and posted her second bogey-free round of the week. She has dropped only one shot at Highland Meadows, in Friday's second round.

The 2007 Kraft Nabisco champion began last week's final round at the Wegmans LPGA in second place, also four strokes back, but struggled to a 78 in the rain and dropped from second place into a tie for 15th.

"It's the same thing that happened last week -- I just have to come from behind," Pressel said Saturday. "This course is going to have some very low numbers."

The 21-year-old American last hoisted a trophy at the Kapalua LPGA Classic in October, her second win.

Kim, 20, is going for her first tour win. She made five birdies in her first 10 holes Saturday and eagled the par-five 17th, sinking a lob-wedge shot from 35 yards.

"It was a very clean round," Kim said through a translator. "I had a great feeling about all of my shots today, and I had good feeling with my putter."
