Jin Young Ko’s worst round on the LPGA, an 8-over 80, came on home soil after a two-month break from the tour to nurse a nagging wrist injury. The World No. 1 posted a catastrophic 10 on the par-5 18th at Oak Valley Country Club to close her round.
The top three players in the world were grouped together on Thursday at the BMW Ladies Championship. Ko played alongside hotshot rookie Atthaya Thitikul, who posted a course-record 63 to pace the field, and No. 2-ranked Minjee Lee, who shot 70.
