Stephanie Meadow is just one shot off the lead after an opening-round 65 at the LPGA's NW Arkansas Championship.
The Antrim native hit four birdies and an eagle on the last as she carded a flawless six under par total on the first day of the three-round event.
Meadow is one of six players who are a shot behind the joint leaders, two-time major winner Anna Nordqvist of Sweden and Americans Jackie Stoelting and Esther Lee.
Leona Maguire shot a level-par 71 that featured a pair of birdies and two bogeys.
Meadow is back out again at 2.28pm Irish time with Maguire beginning her second round at 6.37pm.
"Today was really good," said Nordqvist, who finished joint 32nd at the Women's British Open last week.
"I feel like I've done a lot of good things the last couple weeks. It just hasn’t really paid off. It’s been a little bit disappointing, a little bit frustrating.
"But I had a pretty good talk with my caddie and fiance the beginning of the week, and I feel like they kept me in it."
Meanwhile, at the Ladies European Tour's Czech Open, Denmark's Emily Pedersen set the pace after an opening 63 that contained an eagle, eight birdies and a solitary bogey.
Pedersen, who came into the event on the back of a tie for 11th in the Women’s Open and losing in a play-off at the ASI Scottish Ladies Open, said: "I am really pleased with my round.
"I reached all of the par fives in two, apart from the 18th, so that always helps, but I had a good stretch where I hit three shots in a row to within a metre (of the hole)."
