Singleton — nicknamed "The Postman" — has won a major pool tournament in Australia.
He claimed victory in the second of two events in the Pockets pro series, an invite-only series involving 28 of Australia’s best players and four New Zealanders.
Singleton took an early dive in the first event in Melbourne, losing in the second round to Michael Scerri.
"I didn’t quite feel ready," Singleton (39) said.
"It was my first tournament since October and I felt a little under-prepared for the event."
On Sunday, Singleton found his best stuff.
He beat New Zealand champion Adam Liley in the first round, and Oceania 9-ball champion Michael Cacciola in the second.
After pipping Craig Stevens 6-4 in a quarterfinal that finished when the match clock ran out, he earned vengeance against Scerri with a 6-5 win in a semifinal that also hit the clock.
Singleton romped home in the final with a 7-2 win over professional snooker player Kurt Dunham.
"Despite winning 11 national titles in New Zealand, this was by far the biggest victory of my career," Singleton said.
"To head over the ditch and beat Australia’s best on their home turf is incredibly difficult.
"There are multiple world champions in the field and it’s an honour to have the opportunity to be able to compete against them — to actually win an event is just something else.
"I didn’t really feel like I had the best preparation. Living in Queenstown and owning a business in the tourism industry, we have just had a crazy couple of months through school holidays, and my practice time was very limited.
"Luckily, I felt relaxed and knew I was in the best possible place mentally. Something just clicked on the Sunday."
Singleton finished last year ranked fifth in seven-foot pool — a foot smaller than regular tournament pool — and was part of the first New Zealand team in over 20 years to compete in a transtasman test in Australia.
He said the series — named for the Pockets venue run by promoter Arthur Titus — was aimed at creating a professional pathway for making seven-foot pool.
There are four more monthly doubleheaders.
Each series features a straight knockout race to seven with a one-hour match clock and 30-second shot clock. The winner’s purse for each is $A10,000 ($NZ11017).
