Kim has played the first seven holes at the Sky 72-Oceans Course in 7-under in the first two rounds. Saturday she had birdies at Nos. 4-7. She had bogeys at Nos. 10 and 17 but countered those with birdies at 14 and 18.
"I played really well in the early part of the round but I struggled with my shots in the last part of the round," Kim said. "I managed to overcome some bad putting. I think I can play well tomorrow if I play the way I played today."
