Ruffels made birdies on three of her opening four holes and added another on the 15th, only to give back a shot on the next for a 3-under 69.
Tavatanakit crushed drives - hitting a 337-yarder on the par-5 11th - and was equally as effective on and around the greens on moving day.
She birdied the first three holes on Saturday and when she made a 15-footer on 11 her advantage was five strokes.
