GOLD CANYON, Ariz. — Jenny Shin of South Korea had a run of five straight birdies to close out her front nine on the way to a 5-under 67 on Friday and shared the lead with Maddie Szeryk of Canada and Moriya Jutanugarn of Thailand after two rounds of the LPGA Drive on Championship.

Jutanugarn raced up the leaderboard, following an opening 67 with a bogey-free 7-under 65 that included an eagle and five birdies. Szeryk pieced together a round that included an eagle and six birdies, including one on her final hole, while Shin used seven birides to offset two bogeys to get to 12-under 132 at Superstition Mountain Golf and Country Club in the LPGA’s first full-field event of the year.

American Lilia Vu shot 66 and was a stroke off the lead, while South Korea’s Na Rin An and American Alison Lee were tied for fifth place at 10 under.

No. 3-ranked Jin Young Ko, a winner two weeks ago in Singapore, was among eight players tied for seventh place at 9 under on the crowded leaderboard.

The event marks the debut of the tour’s new cut policy. The cutline after 36 holes includes the top 65 players and ties advancing to the weekend. Previously, the top 70 players and ties advanced to the final rounds.

The cutline fell at 3 under, with 76 players advancing. Two of the big names missing the cut included three-time major winner Anna Nordqvist of Sweden and two-time major champion Brooke Henderson of Canada, both at 1 under.
