South Korea's Eun-Hee Ji is poised to romp to victory at the LPGA's Taiwan Championship after opening up a six-shot lead after the third round.
Ji carded a three-under 69 on Saturday at the Miramar Resort and Country Club in Taipei to sit at 10-under overall and ensure a big gap to the rest of the field.
Australia's Su Oh, who was just two strokes off the lead following a second-round 66, had a horror follow-up.
Oh signed for a seven-over 79 that was blighted by a triple-bogey eight on the par-five 6th hole.
In equal second place and needing a sizzling final round to have any chance of reeling in Ji are New Zealand's Lydia Ko and South Korea's Jenny Shin at four-under.
Ji shared the overnight lead with Shin and recovered from a bogey on the par-four fifth with four birdies.
Ko carded seven birdies against a bogey and a double bogey for a 68.
Shin had three bogeys on her way to a 75.
Cristie Kerr shot a 70 and was tied for fourth in a group that included fellow American Brittany Altomare (75).
World No.1 So Yeon Ryu and No.2 Sung Hyun Park, the US LPGA Tour rookie of the year, struggled to find their rhythm.
Ryu finished with a 75 for a share of 16th place, and Park was six-over after a 73.
