Three more English players are within six shots of the lead heading into the final round.
Georgia Hall, the 2018 Women’s Open champion, was another player to fly up the leaderboard thanks to a fast start.
Like Hull, Hall dropped her first shot of the day at the 14th and followed that up with another bogey at the 15th as she carded a four-under 68.
“Obviously I’m very happy with my round, but I think I let some go at the end,” she said.
“I feel like it could be a bit better. I think if I can get started tomorrow like I did today, then we’ll see what happens and see where I am.”
Lottie Woad and Mimi Rhodes are both three under for the championship and just outside the top 10 following rounds of 71 and 70 respectively.
While many prospered in the Saturday sunshine, the challenge of world number one Nelly Korda faded with a two-over round of 74, which left the American level par for the tournament.
