Hull rose up the leaderboard after a course-record 62 in the second round, and a six-under 67 in the third - including nine birdies - meant she surged into second place, just three shots off Huang after the Canadian posted a course-best third-round 65.
Hull, who finished tied sixth at the AIG Women's Open earlier this month, notched four birdies and two bogies on the front nine, and just one bogey accompanied five birdies on the back nine. It meant the five-time LET winner kept the pressure firmly on going into Sunday's final round.
