Jin Young Ko put on a dominant performance at the CME Group Tour Championship, shooting a bogey-free 63 in Sunday’s final round to defend her title.

Firing nine birdies on the day, Ko finished 23-under for the CME trophy and $1.5 million in prize money.

“I played really well this week and this week was amazing I think,” said Ko following the victory.

The 26-year-old hit a staggering 63 greens in regulation in an unprecedented streak for a record-breaking week of golf.

Ko’s win in the last event of the season marks her fifth on the year, propelling her back in front of Nelly Korda for the Player of the Year Award. Korda and Ko have traded places as world No. 1, with the American notching four wins during the 2021 season.

With 211 points, Ko also locked up the LPGA Player of the Year honors, squeezing past Korda with 197.
