Mina Harigae sits atop the leaderboard after the opening round of the US Women's Open despite a historic performance from Swedish amateur Ingrid Lindblad.

The 22-year-old Lindblad fired the lowest score by an amateur in the event's history to set the early clubhouse lead at Pine Needles, before being eclipsed by the American's superb 64.

Playing alongside her idol Annika Sorenstam, Lindblad carded seven birdies and one bogey in an opening six-under-par 65, surpassing the previous best of 66 which has been achieved three times, most recently by Gina Kim in 2019.

Ingrid Lindblad was in blistering form at the US Women's Open

"I hit a few shots close to the pin and then my putting was great today," Lindblad said. "Made a few par saves and made a few putts for birdies. It just worked from fairway to green.

"I felt like the course would be a little bit more narrow. I missed a few tee shots today that I thought would be a little bit more off, but then I get to the ball and I'm like, oh, it's fine.

"The green areas were tough. You had to hit the right section of the green to not run off the slopes and everything. It's a great US Open course."

Leona Maguire is half a dozen shots back from the leader, tied for 22nd on one-under par after a round that included three bogeys and four birdies.

Stephanie Meadow finished with a one-over 72. Having started disastrously with two bogeys in her opening three holes she played the remainder in one under.
