Two-time LPGA Tour winner Thitikul, 19, picked up five birdies in her last nine holes at Oak Valley Country Club in South Korea to leave herself in command with 18 holes to play.

Leona Maguire is one-under after shooting 71, her best round of the tournament so far. The Cavan woman had opened with two level-par 72s in a steady if unspectacular showing.

Meanwhile Stephanie Meadow endured a frustrating day at the office, a four-over 76 leaving her five-over-par.
