Minjee Lee is staying cool after closing in on Australian golf history with the round of the week to surge into a share of the third-round lead at the mega-money Women's US Open in Pennsylvania.
Lee carded a masterful four-under-par 66 at Lancaster Country Club to reel in halfway leader Wichanee Meechai (67) and march ominously towards a second Open title in three years.
Much more than a record $2.4 million ($A3.6 million) winner's cheque will be at stake on Sunday (Monday AEST).
