Jiyai Shin posted a 3-under 68 on Friday to stay atop the leaderboard after the second round of the Kingsmill Championship.
Shin, the first-round leader, finished 36 holes at 12-under 130 and is one stroke ahead of Danielle Kang, who fired a 7-under 64 Friday at Kingsmill Resort.
Paula Creamer shot a 4-under 67 in round two and is tied for third place with Dewi Claire Schreefel, who carded her second straight, 5-under 66. The pair is knotted at 10-under 132.
The first round was completed Friday morning after darkness halted play on Thursday. There was a 2-hour weather delay on Tuesday as well, but the second round was completed on Friday.
Shin fired a 9-under 62 in round one and wasted little time in getting into red figures in the second round. She birdied the par-5 second, then collected her next birdie at the next par-5, the seventh.
Shin was 11-under par and got to 12-under immediately after the turn. She birdied the 10th and two holes later, birdied No. 12 to reach 13-under par.
It appeared that Shin would cruise into the clubhouse with a decent-sized lead and a par-5 to go, but that didn't happen. Shin failed to birdie the par-5 15th and bogeyed the 16th to fall back to minus-12.
Shin parred her last two and Kang closed the margin to a stroke.
"The greens were a little bit slower, so I missed a few chances with my putting," said Shin. "I still feel good so I just look forward to the weekend."
Shin was once the No. 1 player in the world, but has fallen on hard times in recent years with injuries and inconsistent play. She hasn't won since late in the 2010 season, but feels comfortable where she's at this week.
"I'm used to the competition, I'm used to the pressure and nerves, too, and also I really like that feeling," said Shin. "So I can't wait for the play for the weekend."
Lexi Thompson (66) and Azahara Munoz (68) share fifth at 9-under par.
Stacy Lewis, who is second on this year's money list, fired a 65 on Friday and is tied for seventh place with Maria Hjorth, who posted a 2-under 69. The pair is knotted at minus-8.
NOTES: The 36-hole cut fell at 1-under 141 and Juli Inkster, Brittany Lincicome, Michelle Wie and Cristie Kerr, who won this event the last time it was staged in 2009, all missed the cut...Leta Lindley also missed the weekend and has retired from the tour after 18 years.
