Defending champion Sei Young Kim shot a 5-under 67 on Saturday to reach 13-under 203 and take a one shot lead over Jin Young Ko heading into the final day.

"My vibe was really good because warmer weather, and then I play pairing with Jin Young and Lexi (Thompson). Those are my favorite player, so yeah, it was fun. We wasn't talking much but it was very comfortable and chill out there."

A win on Sunday could see her win the LPGA money title, Player of the Year and move to number 1 in the world.

"Really good chance to chase everything," said Kim. "If I play well tomorrow, good chance."

To move to number 1 ahead of Ko, who has held the position for 73 successive weeks, she would need to win and for Ko to finish solo 10th or worse.

Ko made only three birdies but was bogey-free for a 69.

"I said yesterday my goal is like just bogey-free round on the weekend, so I made it today," said Ko. "I'm looking forward to tomorrow."

Kim and Ko are friends as well as rivals and enjoy playing together.

"Always fun playing with her," Ko said. "We play together last year and we played -- we practiced together at the U.S. Open last week. So we knows each other. But this is competition, so we are close but we have to separate on the course."

Ko is playing in only her fourth LPGA event this season after spending most of the year in South Korea but still has a chance to win the money title following her tie for second place in the U.S. Women's Open last week. The winner's prize money for the CME Group Tour Championship is down to $1.1 million this year but is still the richest in women's golf and Ko is 13th on the list with $567,925 while Kim is second with $1,207,438.

Inbee Park, who tops the money list with $1,365,138, was tied for 28th at 3-under after her third 71 in a row.
