England's Georgia Hall was born during the 1996 Masters and she produced a Nick Faldo-like performance to win the Ricoh Women's British Open in Lancashire on Sunday.
She followed Stupples and Catriona Matthew - in 2009 at Lytham - as the only British winners of the Women's British Open since it achieved major status in 2001.
Trailing Phatlum by a shot overnight, the 22-year-old from Bournemouth held her nerve as the pair traded birdies in a compelling contest that effectively turned in to matchplay on the back nine.
After England's Georgia Hall claimed her maiden major title at the Women's British Open, we look at her career highlights so far. "I was so happy". I've gotta go out there tomorrow and try to play my best and maybe be a little bit more aggressive than I had been going.
"I finished third past year and that experience definitely helped today".
She had three birdies and three bogeys offset each other, but a double bogey on the par-four 17th hole put her at two over for the round.More news: Trump going ahead with tariffs on $16B in Chinese imports
Hall immediately pulled level with Phatlum with a birdie on the first on Sunday but was two down on her opponent by the time they had completed hole fives.
Sports Minister Tracey Crouch praised Hall's performance, saying: "Congratulations to Georgia Hall on winning her first major in what was an incredible performance".
Ahead of a tournament in Abu Dhabi a year ago, Hall hit a drive of 579 yards on Yas Marina race track, believed to be the world's longest drive by a female golfer.
In 2017, Hall returned to the Women's British Open to finish in tied-third, a high she matched in the World Ladies Championship.
"So many people were behind me and supporting me".

As well as netting the £383,000 prize money she also won praise from Dame Laura Davies DBE, the most accomplished female golfer of time, who called her "sensational" and her progress in the sport "meteoric". I don't think it has all sunk in for me.
The resulting bogey saw the 28-year-old's lead cut to a single shot and Hall kept it that way thanks to a superb par save on the ninth after finding a greenside bunker with her tee shot. "I'm in a pretty good position".
That same year, Hall represented Team GB at the 2013 Youth Olympic Festival where she won two golds and was part of the European team at the Junior Solheim Cup.
Phatlum, the third-round leader, came out strong with four birdies over the first six holes.
Ryu So-yeon was third at 11 under, one shot behind Hall after climbing the leaderboard with a run of six birdies from the fifth to the 12th.
Cheered on by a large gallery, Hall finished at 17-under 271, becoming the second English player to win the championship after Karen Stupples in 2004.More news: Google’s Pixel 3 XL could come with Pixel Bud-style headphones
