After a solid first half of the year as an LPGA member, Hall earned her first top-10 finish at the Thornberry Creek LPGA Classic last month, and she has now produced the finest performance of her career to win her maiden major title.
Georgia Hall hopes her Women's British Open victory will inspire girls to turn to golf and help attract new sponsors to the Ladies European Tour.
He marked his ball, turned toward the back of the green and saw his grandparents, Paul and Phyllis Thomas, who had never seen him win since his joined the PGA Tour.
Struggling to hold back the tears at the presentation, she said: "This is for you Grandad".
Fittingly she did so with her father Wayne acting as her caddie, the former two-handicapper having named his daughter in honour of Nick Faldo's Masters triumph in Augusta, Georgia, in 1996.
The classy South Korean will rue the four shots she dropped at the 3rd and 4th holes but she would birdie seven holes from that point to complete her best Women's British Open.
When Georgia Hall pulled even with Pornanong Phatlum with birdie at the 13th, the final round went to match play.
And after her tied third finish at last year's Open at Kingsbarns she vowed to improve on that - and she most certainly did, finishing with a five-under-par 67 for a 17-under 271 total to become the first English major victor since Karen Stupples in 2004.
Ahead of a tournament in Abu Dhabi previous year, Hall hit a drive of 579 yards on Yas Marina race track, believed to be the world's longest drive by a female golfer.
She represented Europe at the Junior Solheim Cup in Colorado in 2013, and a year later she lined up alongside Bronte Law and Steph Meadow in the Great Britain and Ireland team at the Curtis Cup.
"It's wonderful to join the list of British major winners". Her previous best had been in a tie for 3rd in 2015. Phatlum found trouble at the 17th and missed a short putt for bogey to give Hall a three-stroke lead with one hole play.
"I did not hit the ball as well today but we had so much control and I had a very clean card at the end".
"I told myself just to stay calm the whole way and not think about anything".
Both players had a chance to birdie the 13th and, after Phatlum missed her attempt, Hall took full advantage of being on a similar line to make the flawless read and hole from 10ft.
"I got a lot of experience, and just very nervous today, more nervous".
"I've had a game plan", Pornanong said.
"She is from here and everyone is rooting for her". "I'm not allowed to show any emotion because if I show I'm happy that's not right", dad Wayne said.
Three - Minjee Lee, Mamiko Higa, and Georgia Hall - were, like Phatlum, playing for their first major championship title.
She was at 13 under overall, one stroke ahead of playing partner Georgina Hall of England, whose scrambling through an erratic round kept her in contention also for a first major title.
