Lexi Thompson has continued her remarkable run of form of late by taking the 54 hole lead at the Meijer LPGA Classic in Grand Rapids in MI, the 22 year old's lead a narrow one, however, just one ahead of the first and second round leader Brooke Henderson, Koreans Jenny Shin and Sung Hyun Park and South Africa's Lee-Anne Pace.
Overnight leader Brooke Henderson, who carded a third-round 67, joins Pace and Korean duo Sung Hyun Park and Jenny Shin in a tie for second place on a three- round tally of 197.
Henderson birdied Nos. 12 and 13 and closed with five pars.
Ko's two-round total of 136 leaves her six strokes shy of Henderson, who fired a four-under 67 which included three bogeys to maintain her two-stroke lead.
"It's great to see my name up there", she said.
2015 champion Lexi Thompson made 4 birdies on the back 9 and shot 64, she leads by 1 shot at -15.
"I played really solid, I made really good putts", said Ciganda.
Oh went on a birdie blitz throughout the middle part of her round, making six birdied between holes four and 12, before a bogey at the par-three 14th brought her charge to an end. "I'm just excited. It was a good week for me here past year so I have great memories".
"On a day like today when you don't know if you're going to have further rain delays or how the course is playing, I think it was really important to hit the fairways and I think that I was doing pretty well out there", Ko said.
"I was surprised when I looked at the leaderboard and had a two-shot lead on the 18th green but I'm super happy", Henderson said.
New Zealand's Lydio Ko finished the tournament in a tie for tenth after a final round one-under 68 while Australia's Sarah Jane Smith finished in a tie for 37th.
Kim had her second 70 to make the cut on the number.
