Leona Maguire slipped down the leaderboard after a third-round 73 at the BMW Ladies Championship in South Korea.

The Cavan woman hit three birdies but also shipped four bogeys in a one-over round that leaves her -1 and in a share of 55th place, well off the top-six finish she needs to be in with a chance of being named LPGA Rookie of the Year.

Home player Hee Jeong Lim posted a seven-under 65 to take a four-stroke lead heading into the final round.

Lim has yet to record a bogey after three rounds as she set the 54-hole course record (198). The previous best was 203, set last year by Somi Lee and Seung Yeon Lee.

"I think recently there was an event where I had one bogey-free round. But three consecutive bogey-free rounds I think is a first time for me," Lim said.

One of Lim's seven birdies on the day was on No. 11 after she missed her first fairway for the tournament, not that she noticed.

"I wasn't necessarily aware of the fact that that was the first fairway that I missed during this event, Lim said. "But I'm not really used to missing the fairway. I usually keep the fairway pretty well."

Lim began the day in a tie with fellow South Korean Na Rin An, who finished in a tie for second with a 3-under 69 after mixing six birdies with three bogeys on the par-72 LPGA International Busan course.

It's just the second LPGA start for An, but she says she's welcoming the pressure Sunday will bring.

"I'm in the position where I'm really trying to catch up to the lead," An said. "And I think that that pressure is actually going to be beneficial for me tomorrow, and I think that I'll be really able to enjoy the position that I am in tomorrow."

World No. 2 Jin Young Ko, of South Korea, joined An in the tie for second at 14-under with a bogey-free round of 67 one day after shooting eight-under 64 while major champion Danielle Kang (68) and South Korea's Hae Ran Ryu are tied for fourth place at 13-under, five strokes off Lim's lead.

Another major champion, In Gee Chun, is another stroke back at 12-under in a tie for sixth with Australia's Minjee Lee.

Lim, An and Ryu are all bidding to be the second non-LPGA Tour member to win an event this year (2021 US Women's Open champ Yuki Saso is the other).

A victory by any of the trio would allow them to immediately accept LPGA Tour membership.
