Play on the River Course at the Kingsmill Resort was delayed for a number of hours on Sunday due to thunderstorms in the area and as a result the last handful of groups will return on Monday to complete their rounds.
It's Minjee Lee who holds the aces heading into the extra day, with Australian seven-under after 15 holes of her final round for an overall total of 16-under.
The 18-year-old holds a four-stroke advantage over Alison Lee who has completed 14 holes, with Suzann Pettersen, Hyo Joo Kim, Paula Creamer, So Yeon Ryu and overnight leader Perrine Delacour a further two strokes back.
Minjee Lee made a solid start to proceedings on Sunday, taking the turn in 32, before making her move on the back nine. The Perth-born player rattled off three birdies in four holes from the 11th to the 14th before sinking an eagle on the 15th to stretch her advantage even further.
Conversely, Alison Lee struggled to get going on the back nine, with a birdie at the 10th followed by four consecutive pars before darkness brought a close to the day.
Third round leader Delacour began the day poorly with bogeys at the first, fourth and sixth. Birdies at the seventh and 12th stopped the backwards slide, but with Delacour unable to string together numerous birdies, the Frenchwomen's title hopes ended.
World number one Lydia Ko posted a final round 69 to finish the tournament on five-under, ten shots off the back set by Minjee Lee.
