Yuka Saso of the Philippines produced a second consecutive stellar round Friday for a 2-shot lead at the midpoint of the Lotte Championship in Kapolei, Hawaii.
Saso, who shared first place after the opening round, carded a second consecutive 8-under-par 64 at Kapolei Golf Club on the island of Oahu.
Her 16-under 128 total has her in front of New Zealand's Lydia Ko, who recorded the best score of the tournament on Friday, a 9-under 63 that leaves her 14 under overall.
Spain's Luna Sobron Galmes (second-round 64), South Korea's Hyo Joo Kim (65), South Korea's So Yeon Ryu (68) and Nelly Korda (68) share third place at 11 under.
Brianna Do (66), Ally Ewing (69) and South Korea's A Lim Kim (64) are tied for tied for seventh place at 10 under.
Six players, including first-round co-leader Brittany Altomare (71) and amateur Rose Zhang (68), are seven strokes behind Saso, tied for 10th.
Saso, 19, is a regular on the LPGA of Japan Tour, but she finished in the top 15 at last year's US Women's Open. She is looking for her first victory on the US-based LPGA Tour.
Her scorecard Friday featured nine birdies, including four in a row around the turn, and just one bogey.
"Two more days, I'm trying to get used to it," said Saso, who admitted she was playing this course for the first time this week. "It's like Philippines but colder than Philippines and windier than Philippines. I made some good putts, had good up and downs, my driving was very consistent today."
Ko, 23, already has 15 LPGA wins, including two majors, but she hasn't been victorious since April 2018. Her bogey-free round Friday included three different streaks of back-to-back birdies.
"I started off well birdieing my first two holes, and then I think I just continuously gave myself opportunities," Ko said. "Especially around a golf course like this, the more times you're putting for birdie or having chances to putt for birdie the better. ...
"Especially when the winds come, I think it's a course where some players can go really low, so feel like I was able to do a pretty good job at that, and nice finishing off with a birdie on the last (hole)."
Zhang, who started on the back nine, had a run of three consecutive birdies before making the turn after consecutive bogeys. The 17-year-old from Southern California closed her round by birdieing three of her last four holes.
"Everything was going pretty well in that birdie stretch, then I did kind of falter on 17 and 18," Zhang said. "It was just like minor mistakes, and then I also pulled it into the water. But I think I lessened the mistakes out here today and just came back on the back nine."
