Lee shares US Women's Open lead with Harigae after birdie blitz

Seven-time LPGA Tour winner Minjee Lee has claimed her spot atop the leaderboard alongside first-round leader Mina Harigae at the US Women's Open.

The Australian started strongly on the second day with a pair of birdies and claimed another four, along with a bogey on the back nine, to card a 66 that had her at nine-under par at Pine Needles.

"The golf course can really catch up to you quickly, so just trying to take whatever I have in front of me as I go and just try to take... whenever I have a birdie opportunity, I try to take advantage of that," Lee said.

Harigae failed to replicate her superb opening 64 and had to settle for a 69 after mixing five birdies with three bogeys in North Carolina to be at nine under.

The American, who attended the state's Duke University before leaving after one year to turn professional in 2009, admitted the course had played differently for her during the second round.

"Since it was the morning fairways were a little softer, greens were a little softer, so my drives weren't going as far and I had a little longer clubs in," Harigae said, adding: "The golf ball was able to hold better too, so it was all right out there."

South Korea's Hye-Jin Choi, who finished runner-up at the tournament in 2017 while still a 17-year-old amateur, was two strokes off the pace at the halfway point.

Choi's 64 had her one shot off the championship scoring record and tied with three-time major champion Anna Nordqvist of Sweden at seven under.

Fellow Swede Ingrid Lindblad, who on Thursday fired the lowest score by an amateur in the event's history with 65, shot a 71 to be three strokes back at six under.
