Madelene Sagstrom scored a blistering 10-under 62 on Friday and holds a one-shot lead over Carlota Ciganda after two rounds of the Gainbridge LPGA at Boca Raton, Fla.
Sagstrom carded 11 birdies against one bogey during her second trip around Boca Rio Golf Club. The Swede needed just 23 putts during the splendid round and sits at 10-under 134 at the midway point.
"I kept making putts," Sagstrom said after Friday's round. "And I was like, 'Is this going to end, or am I going to just keep making putts?' Because I was hitting really good shots in the beginning."
Sagstrom made seven birdies while posting a 29 on the front nine. She had four more birdies on the back nine, with her lone bogey coming on 17.
Sagstrom shot an opening-round 72, so the scorching showing on Friday was a surprise to her.
"Oh, definitely. I couldn't have expected it, honestly," said Sagstrom, who is ranked 116th in the world rankings. "I just kind of find the flow on the front nine, and I tried to keep it going, and it really worked my way today."
Ciganda, of Spain, shot a six-under 66 to follow up an opening 69. Cydney Clanton, Jennifer Song and Japan's Nasa Hataoka all shot 64 and sit two shots off the lead.
First-round leader Jessica Korda shot a 1-over 73 and is tied for eighth place at 139, five shots off the lead.
Ciganda had an opportunity to hold a share of the lead, but she bogeyed No. 9, her final hole of the round. She also bogeyed 18 but made eight birdies during a round in which she hit 17 of 18 greens.
"Very happy with the score," Ciganda said afterward. "Yeah, the swing feels pretty good. I have been hitting a lots of greens, trying to achieve the less as possible in the scores. And I made a few good putts, and yeah, very happy with those eight birdies."
Clanton achieved a career-best score as she recorded an eagle on the par-5, 16th hole and knocked in eight birdies -- including five in a row -- while suffering two bogeys.
"Tomorrow is a totally new day," Clanton said. "And so hopefully I can find the rhythm early and just kind of keep riding the momentum as long as possible. But it's still one shot at a time, one hole at a time."
Song had an eagle on No. 1 -- her 10th hole of the day -- and six birdies during a bogey-free round that also was a career best. Japan's Hataoka also didn't have any bogeys while recording eight birdies.
South Korea's Sei Young Kim (69) is in sixth place at 7-under 137, while France's Celine Boutier (67) is at 6 under.
Jaye Marie Green (66), Danielle Kang (67), England's Bronte Law (66) and Thailand's Moriya Jutanugarn (67) are in the pack of golfers tied with Korda.
Canadian star Brooke Henderson (68) is tied for 13th place at 4 under, while Lexi Thompson is tied for 19th at 3-under 141.
It was a rough two days for Mexico's Gaby Lopez, who captured last week's Diamond Resorts Tournament of Champions. Lopez shot a 73 on Friday after a first-round 78 and missed the cut at 7-over 151.
South Korea's Inbee Park (72) also missed the cut at 146.
