NAPLES, Fla. - Sei Young Kim had only one birdie on the back nine and held on for a 4-under 68 and a one-shot lead over Nelly Korda, who made a charge going into the final round of the CME Group Tour Championship with the richest prize ever in women’s golf on the line.

Kim led by as many as five shots with three birdies over the opening seven holes, but when she stopped converting birdie chances on the back nine of Tiburon Golf Club, Korda made her move.

Korda began the back nine with three straight birdies, including a bunker shot she holed, and shot 31 on the back for a 66.

Kim was at 16-under 200 and will be in the final group with Korda. At stake is $1.5 million to the winner.
