They knew he could play – when you win the Australian Open aged 21 you’ve rather announced yourself.

But win on the US PGA Tour in a field containing Major winners Phil Mickelson, Bryson DeChambeau and Hideki Matsuyama and you stamp yourself, as Ron Burgundy once said, as kind of a big deal.

Cameron Davis, 26, a product of Monash Country Club in the rolling green eucalyptus forests of Ingleside, claimed his maiden PGA Tour title – the Rocket Mortgage Classic – on Monday morning after a 5-hole play-off with American Troy Merritt and Joaquin Niemann of Chile.

Davis’s charge at the title appeared to be over after a bogey on 16 but he holed out for eagle on 17 and birdied the last hole to card 67 to get himself into the play-off.

Davis then played exquisite, precision iron shots and shaved holes on the putting green before finally killing off Merritt of Osage, Iowa.

Davis pocketed $1.8 million for the feat.

Head professional at Monash, Daniel Paton, said it was very exciting to see a Monash product winning on such a big stage.

“It was very cool to see him play so well to get into the play-off and then really turn it on to win.

“His golf over the closing holes was sensational.

“He’s always had talent, that’s never been in doubt – he can play almost as well left-handed as right-.

“But this win shows what many of us at Monash have always known: he has a real killer instinct to win,” Paton said.

Davis played Senior Pennants for Monash for several years and won the Australian Amateur Championship in 2015.

Two years later he shot 64 in the last round at The Australian Golf Club to claim the Australian Open at the age of 21.

Paton said everyone at Monash is hugely proud of Davis.

“Everyone at Monash, the entire membership and staff, has invested in him. Not only is he a ridiculously good player but he’s a terrific bloke.

“After he won the Australian Open he turned up to play in our Wednesday stableford competition with three club members he didn’t know!

“Hopefully this win in America sets him up for a run at bigger things,” Paton said.

In a sensational weekend for Australian golf, Lucas Herbert won the Irish Open, Stephanie Kyriacou won Big Green Egg Open in the Netherlands, Dimi Papadatos finished second in the Kaskada Golf Challenge on the European Challenge Tour, while Queensland amateur Louis Dobbelaar won the prestigious North and South Amateur.
