With a three-stroke lead heading down the 18th hole at Royal Lytham & St. Annes on Sunday, it was clear England's own Georgia Hall was going to win the Ricoh Women's British Open, barring a historic disaster.
Hall took the outright lead for the first time in the tournament after a 20-foot putt for birdie at the 16th hole and went down the last with a three-shot lead after Pornanong, ranked No. 97 and also seeking her first major and LPGA title, missed a two-foot putt to make double-bogey at No. 17. "I've come this far, so all I do now is put on my best play", she said.
According to Sky Sports, Hall's name was inspired by Faldo's sensational victory-the Masters takes place in the city of Augusta in the USA state Georgia.
Hall - who was named in honour of the American state that hosts the Masters - also revealed she had spoken to former Open victor Tom Lehman, who won at Lytham St Anne's in 1996.
The 22-year-old is the first British golfer to win a women's major since Scotland's Catriona Matthew won this event in 2009, and England's first since Karen Stupples did likewise five years earlier. It was my goal when I was nine to win the British Open.
Starting the day one shot off the pace, the world No.8 made bogey on her third hole before stringing together three birdies to head in the right direction.
Pornanong began the day with a one-shot lead over Hall and four birdies from her first six holes doubled her advantage.
It was a 5-under 67 for Hall, who finished the week at 17 under.
Behind Phatlum in the lead, two-time major victor So Yeon-Ryu from South Korea is third, while Japan's Marmiko Higa is in a tie for fourth. He had a four-shot lead and faced a 15-foot birdie putt on the final hole that would only determine his margin of victory. I am so happy. Hall averaged 28 putts per round and was seven-for-seven in sand saves. "I just loved every minute". To get six birdies on the final round of a major is not bad! 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.
Hall added: "I was in the final round a year ago [at Kingsbarns] and that is definitely going to help me". She was in the final group in the Open previous year, and finished in a tie for third.
Also the 2014 and 2015 victor at TPC Twin Cities, the 57-year-old Perry matched Hale Irwin's tournament record of three victories in the final edition of the event that started in 1993 at Bunker Hills.
"I was loving it, deep down, hitting the shots under pressure", said Hall, who barely showed any emotion all round.
World No. 1 Dustin Johnson shot 64 and for third on 10-under par.
He closed with a 3-under 69 for a three-stroke victory in the PGA Tour Champions event that is being replaced by the PGA Tour's 3M Open.
