Minjee Lee is threatening to run away with the U.S. Women's Open, taking a three-stroke lead heading into the final round on Saturday.

Lee fired a four-under 67 to move to 13-under after 54 holes, breaking the U.S. Women's Open 54-hole record of 201 set in 1999 by Juli Inkster by a single stroke.

The world number four started the third round slowly, scoring a bogey on the fifth hole to fall two shots behind Mina Harigae.

Lee responded quickly with a birdie on the sixth, before breaking the round open with four consecutive birdies between nine and 12.

Playing alongside Lee in the final group, Harigae faltered meanwhile, firing consecutive bogeys on the 11th and 12th hole respectively.

The past three third-round U.S. Women's Open leaders at Pine Needle have all gone on to win the tournament, including Lee's fellow Australian Karrie Webb in 2001.
