Lydia Ko must wait another day before she begins her fourth round at the US Open.
The final round play was suspended due to course conditions and anticipated inclement weather in Houston, the US Open organisers announced this morning.
Ko, who sits in a share of fifth, had yet tobegin her round.
On Sunday, Ko posted just one birdie, along with two bogies, amongst 15 other par holes in the round but it was still enough to move her to within four shots of leader Hinako Shibuno of Japan.
Shibuno, who won last year's British Open, shot a three-over 74 to hold a one-shot lead over American Amy Olson. Thailand's Moriya Jutanugarn and South Korea's Ji Yeong Kim lie in a share of third at one-under, a shot ahead of Ko and three other players.
Ko said a different wind direction made a tough start to the day.
"I knew the holes would play quite differently but with the first few holes all into the wind and raining from yesterday afternoon and overnight I think definitely made the course a lot softer and hence made it a lot longer…I was just trying to grind my way out there," she said after her round.
"I feel like I could have shot a lower score but at the same time it could have been a lot worse so I'll take what I have today."
