Thailand's Moriya Jutanugarn shot a 2-under 70 on Saturday to maintain a six-stroke lead after the fourth round of the LPGA Tour qualifying tournament.

The 18-year-old Jutanugarn had a 15-under total at LPGA International. The final top 20 in the five-round event will earn full tour status.

Japan's Ayako Uehara was second, also after a 70.

Two-time tour winner Christina Kim, tied for third after the second round, followed her third-round 75 with a 73 to drop into a tie for 24th at 1 under.
