A sensational second round 64 saw Leona Maguire shoot right up the leaderboard at the Aramco Saudi Ladies International in Riyadh.
The Cavan woman had a disappointing first round, carding just one birdie on her way to a 76 that included five bogeys, but on Friday she found serious form to play herself into a good position going into the weekend.
Her eight birdies were evenly split between the front and back nine - finishing with four birdies in her last six holes - and the 29-year-old didn't drop a single shot at Riyadh Golf Club.
By the end of her round she had gone from a share of 66th to joint-fifth on four-under-par, four shots off leader Paphangkorn Tavatanakit, who carded a two-under 70.
"I'm really pleased," said Maguire. "I was a bit frustrated yesterday, I felt like I played better than the score reflected, and conditions were very tough. It was good to hang in there.
"It was nice to get off to a good start today and take advantage of the calmer conditions.
"I felt like I hit it nicely yesterday but didn’t have control of the ball and I hit 15 greens but didn’t putt well. Today, I hit 18 greens and putted better, so that always makes life a little bit easier."
