Thailand's Moriya Jutanugarn shot a 6-under 66 on Thursday to take a three-stroke lead after the second round of the LPGA Tour qualifying tournament.

The 18-year-old Jutanugarn had a 10-under total at LPGA International in the five-round event.

"Eight birdies," Jutanugarn said. "I don't know how come. I'm serious."

Lacey Agnew was second after a 67.

Two-time tour winner Christina Kim was third at 5 under after a 67. She is playing the qualifying tournament for the first time in her career.

"When I was younger, after I got my card on what is now the Symetra Tour, I had vowed that I would never have to go to Q- school," Kim said. "And I would now say that no one should ever be that arrogant.

"But now that I'm here, it has a very unique atmosphere. It's a once in a lifetime opportunity that everyone should do at least once. Not at least, just once. Because it's different."

The final top 20 will earn full tour status.
