Jeongeun Lee6 birdied her final four holes Friday at the Amundi Evian Championship to shoot a 10-under 61 and tie the lowest round ever in major championship history.

She led the early wave of players in the second round with a 36-hole total of 127, good for 15-under par.

That also was a record for two rounds in a major championship, breaking the 129 shot by fellow South Korean In Gee Chun at the 2016 Evian.

Lee6, 25, tied the 61 fired by another South Korean, Hyo Joo Kim, in the 2014 Evian in Evian-Les-Bains, France.

The winner of the US Women's Open in 2019, Lee6 had 10 birdies and no bogeys and needed only 23 putts over 18 holes.

"Every putt looked like it was going to go in," said her caddie.

Lee6 is three shots clear of Thai pair Ariya Jutanugarn (63) and first-round leader Pajaree Anannarukarn, who shot 65.

Leona Maguire shot a one under 70 to move to three under overall.

The Cavan woman had an eagle on the par-four second, three birdies and five bogeys.

She was in a share of 25th, 12 shots behind Lee6, along with fellow Irishwoman Stephanie Meadow, who shot a 68.

Meadow sank seven birdies and dropped four shots in her round.
