Lydia Ko is in command of the Women's PGA Championship heading into the final round as her consistency holds her in good stead following a third-straight round of par or better.
Ko shot her second-straight one-under-par 70 to move to two under overall and take a one-stroke lead over American duo Gerina Piller (71) and Brittany Lincicome (71) heading into the final round after Saturday's play at Sahalee Country Club.
But it was a day to forget for previous joint-leaders Brooke Henderson (73) and Lee Mi-rim (73), who are both now tied for fourth alongside four others.
Not that Ko will be bothered, as she put in a determined display, holing birdies on holes five and six, to head to the back nine in a good position.
A bogey on the 12th brought her back down and she looked to have put herself in a commanding position when she birdied the 15th, but an 18th-hole bogey took some of the gloss off an otherwise exceptional day.
And Ko is hoping to call on her winning experience, having converted third-round leads into wins at the ANA Inspiration and the Evian Championship.
"Going into Evian and ANA I just had very calm thoughts, very positive thoughts, to the final round," she said after the third round.
"I just said 'hey, just go out and enjoy it, and don't worry about what everybody else does. Just focus on the shot you need to hit'.
"That's all I can do, just try my best and have fun. I can't control what somebody else does so it's important for me to focus on my game."
