The Mexican golfer had a five-birdie stretch mid-round, then added two late birdies to finish with a 13-under total of 203 and a five-shot lead going into Sunday's final round at The Lakes.
Japan amateur Keita Nakajima was in second place after 70, while Bradley was tied for third with Australian veteran Marcus Fraser. They were six strokes behind after 71s.
Kuchar, who trailed by a stroke after the second round, shot 73 Saturday and was tied for fifth, seven behind Ancer.
