The top 64 players in the stroke-play portion advance to the match-play part of the tournament, but that field won't be finalized until Wednesday morning. Eight players at 10-over-par 154 were fighting for five spots in the match play, but darkness forced the suspension of play.
Taylor Leon and Mallorie Underwood were eliminated on the first playoff hole. The six remaining players will return to the Settindown Creek course at 7:05 a.m. (et) Wednesday morning to round out the field of 64.
Kim, the reigning U.S. Girls' Junior Champion, tallied four birdies and three bogeys in her round on Tuesday. The 17-year-old, playing in her fifth women's competition, won't change her strategy once the match play starts.
'I'll play no differently than I did in stroke play,' said Kim, who swept six matches en route to victory last month at the Girls' Junior Championship at BanBury Golf Club in Eagle, Idaho. 'I like match play.'
Ashley Knoll shot an even-par 72 and tied for second place with Annie Thurman- Young (71) and Jennie Lee (71). The trio came in at 3-under-par 141.
Morgan Pressel, the co-runner up at this year's U.S. Women's Open, posted a 2-under 70 and finished alone in fifth place at minus-2.
'Obviously, anything can happen so I've got to be ready to get through those six matches,' Pressel said. 'It's a long week. Well, hopefully it's a long week.'
Angela Park (74), Tania Elosequi (72), Taylore Karle (73) and Esther Choe (72) tied for sixth at even-par 144.
Defending champion Jane Park carded a 3-over-par 75 on Tuesday, but easily qualified for match play. She finished two rounds at 2-over-par 146 and tied for 15th.
'I feel good, but my putting was very defensive today and I've got to putt a lot more aggressively tomorrow because that's what match play is all about,' said Jane Park.
