LOS ANGELES — Alison Lee seized a share of the lead at the 81st U.S. Women’s Open on Friday with a second-round 68 in her native Los Angeles area, joining Ruoning Yin at 4-under 138 atop a crowded leaderboard at Riviera.

World No. 1 Nelly Korda jumped into the hunt for her first Women’s Open title by shooting the day’s lowest round at 67, leaving her just two shots back after struggling Thursday.

Opening-round leader Jennifer Kupcho, Sei Young Kim and Mexico’s Gaby Lopez were in a group of six at 3-under 139, while Korda and three others were at 140.

The venerable course at this 100-year-old country club is hosting its first U.S. Women’s Open, and it remained unforgiving for the world’s best. Only two players managed a bogey-free round Friday — including China’s Yin, who semi-jokingly called Riviera “passive aggressive” despite being the only player in the field to shoot two sub-70 rounds so far.

Yin carded her second straight 69 in the same city where she earned her first LPGA Tour victory in 2023, a couple of months before she won the Women’s PGA Championship. She tied for fourth at last year’s U.S. Open at Erin Hills.

Lee played under par for the second straight day at Riviera, highlighted by back-to-back birdies just before the turn. The new mother’s first two rounds are an extension of a strong start to the season that includes a third-place finish at the Mizuho Americas Open four weeks ago.

DUBLIN, Ohio — J.T. Poston stepped onto the putting green Friday at the Memorial just in time to feel the first gust of wind, knowing a tough course was about to get even harder. Part of him was eager to see how a new golf ball to help with the wind was going to perform. It’s safe to say he was pleased.

Poston had eight birdies in a round of 7-under 65, a score best measured by the fact he was nine shots better than the field average, enough for a one-shot lead over Ryan Gerard going into the weekend at Muirfield Village.

Poston was at 9-under 135, a score not many saw coming.

The quality of his round could be measured by the comments of some of his peers. The interview with Tommy Fleetwood began with a statement that it seemed tougher out there.

“Is that a question?” Fleetwood replied. “Yeah, we’ll expand on that. It was pretty brutal, actually.”

Justin Thomas hit a phenomenal flop shot from behind the 18th green and holed a 6-foot par putt to make the cut on the number.

Scottie Scheffler looks nothing like the No. 1 player who has won the Memorial for the last two years. He says he hit the ball as bad as he has in two years. One of them was a shank from a bunker on a par 5. He was close to the cut line at one point. And yet Scheffler still managed to scratch out an even-par 72. He says there were times he felt he was going to shoot 90. Scheffler says he was proud of the way he hung in there. He’s still 10 shots behind.
