Huang, who led from the opening round, started the final day three shots clear and remained in control until the closing holes.

After a birdie at the 15th, Huang found the water at 16 and made a clutch bogey, allowing home favourite Hull to take the lead with a birdie.

But Hull’s advantage lasted just one hole. The Englishwoman four-putted the 17th for a double bogey, putting Huang back in front before the Canadian sealed victory in spectacular fashion by holing her eagle putt on the 18th for a 22-under-par total.

“That was probably the most thrilling round of golf of my life. That was crazy. I have no words. I’m just so shocked,” said Huang.

“I can’t believe I made another eagle [on 18]. I focused on the putt and made a good stroke, and it went in.”

The victory makes Huang the youngest player to win four LET titles, achieving the feat at 17 years, 9 months and 10 days, surpassing Lydia Ko’s previous record.

“A year ago, I was at a really low point in my life, and golf wasn’t really fun for me. I was dealing with all these thoughts, but with the help of my family and all my support, I was able to get myself back together and push through that part,” she said.

Hull finished runner-up at 20-under following a final-round 69, while Singapore’s Shannon Tan fired a nine-under 64 to finish third at 17-under.

Australia’s Kelsey Bennett was fifth at 14-under, one shot behind Thailand’s Patty Tavatanakit.

Huang also moves to second in the LET Order of Merit, with South Africa’s Casandra Alexander retaining the lead.
