LOS ANGELES: Australia鈥檚 Minjee Lee defied difficult, windy conditions with a remarkable bogey-free 3-under par 69 on Saturday to seize a four-stroke lead over Jeeno Thitikul at the Women鈥檚 PGA Championship in Texas.

Lee, chasing her third major title, fired three birdies in one of just three sub-par rounds at Fields Ranch East in Frisco, north of Dallas, where soaring temperatures and wind tested golfers for a third straight day.

鈥淚 just try to stay patient out there,鈥� the 29-year-old said after building a six-under total of 210. 鈥淵ou can鈥檛 get ahead of yourself, especially in these conditions.鈥�

Trailing Jeeno by three to start the day, Lee grabbed her first birdie at the ninth, where she blasted out of a greenside bunker to four feet and made the putt.

She finally took control at the par-5 14th, drilling a 19-foot birdie putt as Jeeno three-putted for a bogey that dropped her three strokes back.

Lee added a birdie at the 15th, and remained bogey free with a par save at 18 鈥� where her second shot raced through the green but she chipped to three feet.

鈥淚 try to stay within myself and play the shot as best as I could,鈥� she said. 鈥淛ust stayed patient, just take it as it comes.鈥�

Lee, whose 10 LPGA victories include major titles at the 2021 Evian Championship and 2022 US Women鈥檚 Open, said there would be plenty of work to do on Sunday despite her four-shot cushion.

鈥淚t鈥檚 just only getting harder and harder just with I think pressure of a major championship, and also just the course just demands so much from you,鈥� she said.

World No.2 Jeeno鈥檚 hopes of a first major title took an early hit with bogeys at the third and sixth.

She rolled in a 12-foot birdie at the eighth, but dropped into a tie for the lead after back-to-back bogeys at 11 and 12.

She bounced back from her bogey at 14 with a birdie at 15, but gave back a shot at the 16th, finishing with a 4-over 76 for 214.

Lee and Jeeno, both based in the Dallas area, were the only players under par heading into the final round.

US veteran Lexi Thompson, playing a limited schedule this season, shook off a horrendous start to post a 3-over par 75 to headline a trio sharing third place on one-over 217.

Thompson opened with a triple-bogey and a bogey and added another bogey at the eighth before she made two birdies coming in.

She was joined on one-over by South Korean Choi Hye-jin, who carded a 72, and Japan鈥檚 Miyu Yamashita, who shot 73.

World No. 1 Nelly Korda had five birdies and five bogeys in her even par 72 to headline a group of four on 218.

鈥淚t鈥檚 brutal out there when it comes to the setup of the golf course, wind conditions, everything,鈥� Korda said. 鈥淚鈥檓 very happy with even par.

鈥淵ou鈥檙e just happy to get 18 under your belt on a day like this,鈥� added the American, who said having substantial waits on several tees only added to the difficulty of the day.

鈥淵ou don鈥檛 want to be spending 20 minutes and getting up to the next tee and then you鈥檙e 15 minutes and getting up to the next tee and it鈥檚 another 15 minutes,鈥� she said. 鈥淭here is just, like, no momentum in it.鈥�

Korda was tied with Ireland鈥檚 Leona Maguire, Japan鈥檚 Chizato Iwai, South Korean Lee So-mi and American Yealimi Noh 鈥� who had two eagles but also six bogeys in her 74.

Australian Grace Kim had the low round of the day, firing six birdies in an impressive 4-under par 68 that gave put her among a group of five players on three-over 219.
