After high winds halted Thursday's first round, Pettersen
returned to the Mission Hills Country club course early on
Friday to finish off a four-under-par 68.
She followed in the afternoon with a 69 to reach seven-under
before the second round was stopped due to darkness.
"I played really good. I played quite a bit of golf," Pettersen
told the LPGA website.
"Just Steady Eddie, just plugging along, hitting good shots,
giving myself chances."
Fifty-six players will have to return to the course on Saturday
to complete their second round.
A group of six players trail Pettersen by a stroke including
Park In-bee and the 2014 U.S. Women's Open champion Michelle
Wie, who was only through eight holes of her round. South Korean
Park was at eight-under before bogeying her final two holes to
fall to six-under.
French veteran Karine Icher was the first-round leader after
shooting a 67 and was also at six-under through 11 holes in her
World number one and defending champion Lydio Ko of New Zealand
was at four-under following her second round 70.
Pettersen continued her strong form on the Mission Hills Country
Club course where she has seven top 10 finishes.
"How can you not love this place? It's heaven for golf and great
surroundings," Pettersen said.
"Just really got to be on your A-game to feel like you can
attack this course. I'm driving the ball well so I'm giving
myself good irons into the greens."
