The clubs Sei Young Kim used to win the Thornberry Creek Classic

Sei Young Kim put on a display of ridiculous golf at the LPGA’s Thornberry Creek Classic, finishing with a video-game-like 31 under par total to establish a new 72-hole LPGA scoring record, shattering the old mark—one she shared with Annika Sorenstam—by four shots.

“After the Founders Cup [where she tied Sorenstam in 2017], I got new goals," Kim said. "I wish I could break the record. It's really unbelievable."

Unbelievable certainly described Kim’s play. She shot rounds of 63-65-64-65 to win by nine shots over Carlota Ciganda. Anna Nordqvist shout four rounds of 67 and stood 11 back in a tie for third place.

Over the 72 holes Kim made 31 birdies and one eagle. Her only blemish being a double-bogey 5 on the par-3 17th on Friday. Helping Kim keep her card clean otherwise was the fact that she hit an astounding 67 of 72 greens in regulation, a 93.1 percent clip with her Mizuno MP-18 irons.
