Portland (AFP) - South Korea's Kim In-Kyung fired a five-under 67 to stretch her lead to three shots after the second round of the LPGA Tour's Portland Classic.
Kim, whose only top 25 finish this year came at the Swinging Skirts Classic, ended 36 holes at 12-under-par 132 on Friday. The last of Kim's three career wins on the USLPGA Tour came in the 2010 season.
"The greens were rolling much better in the morning, so that was kind of nice, and I hit the ball well, similar to yesterday. I'm really pleased with how I played on the par-fives," said the 26-year-old Kim.
"I'm really pleased how I played the last two days, and I'm looking forward to the weekend."
Carlota Ciganda and Hur Mi-Jung both fired seven-under 65s in the second round at the Columbia Edgewater Country Club. They moved into a share of second place at nine-under 135. They were joined there by Laura Diaz, who shot 68 in round two.
Last week's winner Ryu So-Yeon carded a 66 to move into fifth place at six under. She was joined there by Mina Harigae (69), China's Lin Xi Yu (68) and Paula Reto (69).
Amelia Lewis is alone in ninth place at seven-under 137 after posting a 71 on Friday.
Kim started her round with birdies on the 10th and 12th. After stumbling to a bogey on the 13th, she came right back with birdies on the 14th and 15th to move to 10-under.
Kim birdied the first before faltering to another bogey on the par-three second. She rebounded with a birdie on the third.
Kim parred three straight from the fourth. She made birdie on the par-five seventh to move to 12-under. Kim parred her final two holes to end there.
Suzann Pettersen rallied with five birdies in her final seven holes to get to six-under-par with a second-round five-under 67.
Defending champion Pettersen and US Solheim Cup captain Juli Inkster (70) are among nine players tied for 10th place.
