The six-year-old gelding won the A$1 million feature over a mile with a strong finish on the outside, saluting by half a length at Kembla Grange on Saturday.
The stable can now confidently set the gelding for the Group 2 Ingham Stakes over the same distance at Randwick on December 10.
“We gave him two runs in weight-for-age good sprints to get him ready for this mile,” Payne told HorseBetting.com.au.
“Now he's had one run at a mile, he'll go on to The Ingham.”
The sprinter now has $1.168 million in prizemoney after notching up his fifth win from 24 starts.
His triumph in Wollongong was his first since taking out a Group 3 race over 1400m in Auckland on December 7, 2019.
But Payne believes more success can come in three weeks.
“We've had two races in mind. We've conquered one, and we've got The Ingham to conquer,” he said.
After a long drought, Riodini was not the only one desperate to enjoy the spoils of victory on the weekend.
“Gai was desperate to win The Gong because she's won so many races here at Kembla,” Payne said.
“When they put this race on a few years ago, Gai wanted to win it.
“She rang straight away. She watched the race and she was over the moon.”
Payne said the Waterhouse & Bott stable was also looking forward to the Gold Coast Magic Millions Raceday on January 14 next year.
“We've got a nice bunch of two-year-olds, so we're looking forward to the Magic Millions,” he said.
