WALTON-ON-THE-HILL, England — Lilia Vu moved into position to become the first American this century to win multiple women’s majors in the same year.

She has company atop the leaderboard, though, in home favorite Charley Hull at the Women’s British Open.

The final major of the year came to life Saturday at Walton Heath, thanks to a third-round collapse from overnight leader Ally Ewing, whose five-shot advantage lasted nine holes before she was swallowed up by a slew of chasers.

First it was Vu, who won the Chevron Championship in April, and then came another American, Angel Yin, before Hull made three straight birdies from No. 15 to join the party.

Vu (67) and Hull (68) shared the lead at 9 under. One shot back was Yin (67), who lost a playoff to Vu at the Chevron, and Hyo Joo Kim (68), while Ewing was two off the lead after shooting a 3-over 75 – nine strokes worse than her second round.

The last American woman to win multiple majors in the same season was Juli Inkster in 1999.

“It’s been a while since I played Chevron that I actually felt pretty decent about my game and where it’s at,” said the No. 6-ranked Vu, who missed the cut at two of the other majors this year’s and then was tied for 42nd at the Evian Championship. “So I’m just going to do the same thing I did today – just focusing on tee shots and giving myself a good opportunity for birdies, and just do that tomorrow, not think too much about the wind.

“Because every time that happens, it just slips away from me.”

More big names are in sight of the lead after a day of strong scoring at the heathland course southwest of London.

Linn Grant, a 24-year-old with a smooth swing and a recent win on the LPGA Tour, is three back after a 68. A stroke further adrift at 5 under is two-time British Open champion Jiyai Shin (69). Top-ranked Nelly Korda can’t be discounted, either, after shooting 69 to be five off the lead.

Rebounding from a bogey at No. 14, Hull made three birdies in a row, headlined by a tee shot to 4 feet at the par-3 17th.

A place in the final pairing was at stake as she went to No. 18, and she pushed her tee shot right and into some heather. She chopped out and got up-and-down for par, a finish that brought a big smile to a player who was runner-up at the U.S. Women’s Open at Pebble Beach last month.

Vu made her move with five birdies in seven holes from No. 5, then picked up two more shots at Nos. 16 and 18.

“I think you’re always nervous, no matter what position you’re in, because if you’re leading, you kind of don’t have the win yet,” Vu said. “You never really have it until the final round, 72nd hole, and you’re done with your putt.”

Ewing, who hasn’t won a major, was tied for the largest 36-hole lead at the Women’s British Open since it became a major in 2001. She still doesn’t think she’s out of contention despite struggling in the third round.

“The nerves were obviously there, but at the same time, I was mentally in a good place to know that I was going to be presented with challenges,” Ewing said. “Didn’t execute shots quite like I wanted to early on, but I fought really hard today, and, you know, I’m teeing it up tomorrow with still a great chance to win this golf tournament.”

PGA: Lucas Glover shot 4-under 66 and will take a one-stroke lead into the final round of the FedEx St. Jude Championship in Memphis, Tennessee.

Glover missed two short birdie putts on his last three holes but got enough out of his round to stay in front at steamy TPC Southwind in the FedEx Cup playoff opener. He was at 14-under 196 as he seeks back-to-back victories after ending a two-year winless streak last weekend at the Wyndham Championship.

Taylor Moore, who won his first PGA Tour title this year at the Valspar Championship, bogeyed his last hole for a 65 and was one shot behind.

Tommy Fleetwood ran off three late birdies for a 66 that left him two shots back as he goes for his first win on American soil. Max Homa (65) and Jordan Spieth (68) were three behind.
