Cristie Kerr eagled the par-5 17th for a one-shot win at the season-ending CME Group Tour Championship in Florida on Sunday, while Lydia Ko held off Park In-bee and Lexi Thompson to claim the $1 million Race to the CME Globe jackpot.
Kerr, 38, claimed her 18th career LPGA title and a $500,000 check by rolling in a three-foot par putt at the 18th to complete a four-under-par 68 for a 17-under 271 total at the Tiburon course in Naples.
Rookie Jang Ha-na of South Korea posted a 69 for 272 to share second place with American Gerina Piller, who fired a 67.
World number one Ko was in a tight battle to hold on to her edge in the jackpot race, with South Korean Park missing a birdie putt at the 17th as did Thompson that would have put them out in front for that prize.
World number two Park shot a 69 for 276 and sixth place in the tournament to finish second in the race, while American Thompson returned a 68 for fourth place on 274.
