Lewis keeps LPGA Classic lead
World number 3 Stacy Lewis will take a one-shot lead into the last day of the Swinging Skirts LPGA Classic after she moved to 10-under.
Seventeen-year-old Lydia Ko is in second place at nine under after also shooting a 68, with Jenny Shin leading the chasing pack a further three shots back.
Lewis, who led the tournament after 36 holes, burst into life on the back nine after a previously steady round of pars with birdies at the 12th, 15th, 16th and 17th holes.
The 29-year-old partially credited her display to the fact that she has been paired with Ko through all three rounds.
"We both play fast and we got into a good rhythm," said Lewis, who is searching for her first tournament victory since winning the British Open in August 2013.
"It's nice to play with someone who is playing well. I think it made both of us elevate our game."
Nevertheless, Lewis said there was still plenty of room for improvement in her game.
"This is probably the worst I've hit the ball all week," she said.
"This course is so hard you can make a bogey really quickly. I was putting well so when I hit a couple of good putts for par, I got some momentum going."
Ko made five birdies during her round, with the only blemish to her scorecard coming with a bogey at the fifth.
"It's fun watching Stacy play," she said.
"She does make me feel like I have to play better. I always knew she was good, her rankings and scores show that.
"It's really good for me, as a rookie, to play with a player like Stacy. It's a great opportunity for me to learn from another great player."
Michelle Wie, who won last week's tournament in Hawaii, was tied for 13th at one-under after a round of 71.
Scotland's Catriona Matthew was the highest-ranked British player on the leaderboard with a round of 74 leaving her in a tie for 17th place at even par.
