Hull struggles after taking early leadpublished at 13:39 British Summer Time 25 August
Hull -2, Jutanugarn -1 (2)
It was looking so good for Charley Hull.
England's Hull shot a superb five-under-par 67 to lead the Open after the opening round at St Andrews.
However, a level-par 72 before a 75 on Saturday means she is five shots back on the leader.
The 28-year-old, who was runner-up in both The Women's Open and US Women's Open last year, will need an impressive final round to secure her first major title.
She has opened her final round with a solid par at the first, and another at the second after her 10-foot birdie putt teetered on the edge of the hole but refused to drop.
Hull is playing with Ariya Jutanugarn, winner of this title in 2016.
