South Korea's Sei Young Kim endured a rough back nine with four consecutive bogeys on Saturday but retained her lead after three rounds at the JM Eagle LA Championship in Tarzana, California.
Ranked 10 in the world, Kim had a one-shot lead entering the day and expanded that to two strokes with a one-under-par 71 to move to 15-under at El Caballero Country Club.
"Oh, wow, it's feel like, yeah, roller coaster," Kim said of her round.
"I didn't know still two-shot lead until the last hole. Yeah, after finish I look at the scoreboard and I still (hold a) two-shot lead. OK, one more day. Yeah, I'm going better tomorrow."
Four players are tied for second at 13 under: Australia's Hannah Green (5-under 67 on Saturday), Thailand's Suvichaya Vinijchaitham (67), South Korea's Ina Yoon (71) and Jessica Porvasnik (68).
