She said: “Today I hit pretty good putts and iron shots. Everything was good, especially the front nine, which was very nice but after the back nine, I struggled, but somehow I coped. I am satisfied with the round.”

The No.2 ranked player on the Korean Ladies Professional Golf Association (KLPGA) can take the No.1 spot on the Korean Money List with her third win of the season at the co-sanctioned event.

She explained: “This season, I want to be top of the money list so I am playing to win.”

Meanwhile, the 2008 champion Hee-Kyung Seo shot 69 and lies in a tie for third place with Young-Ran Jo and Soo-Young Moon on three-under.

Eight players are a shot back in equal sixth place, including Paraguayan Julieta Granada who carded a second round 72 and Korean amateur Julie Yang, who had a 71.

Granada said: “I started off really well on the front nine and then we took a long time on the back nine so I lost my concentration a bit. I hit lots of greens but I was not very concentrated today and it was a little long.

“I hit 16 greens so I had 34 putts and I need to work on my putting. The leaders didn’t go so far ahead which is good for me. Tomorrow I am going to have to go low. If tomorrow is like today they are going to go low so I have to do the same.”

The Netherlands’ Dewi-Claire Schreefel was the next best placed European in joint 14th place on one-under.

The European No.1 Lee-Anne Pace of South Africa, with five wins this season, stands in a group of eight players on three-over-par. England’s Laura Davies, ranked second in Europe after four victories in 2010, added a 71 to her opening 78 to make the cut on the mark at five-over-par, attributing her poor opening round to the pace of play.

The third and final round begins at 7.45am on Sunday from two tees. The leading trio of Reid, Yang and Seo will tee off at 9.39am.
