The 23-year-old teamed up with the Steven Duffy-trained Mad Punta, who lived right up to his name — punching clear at the business end to salute by 5.4m over City Rockstar in the Moama Bowling Club Pace, banking $3320 in prize money.
For Potter, the milestone carried a mix of pride and disbelief.
“At the time I didn’t really process it until after,” she said.
“I don't know whether to be happy - well, I was happy — but I will still lose my five claims (concession), so it’s a little bit sad.”
Still, there was no doubting the significance of the win.
Having been around the game her whole life, Potter has carved out a steady path in the sulky, building momentum across the past two seasons.
“I’ve been driving for about two years now,” she said.
“To get to 100 is a really nice reward for the hard work.”
Although, it wasn’t all smooth sailing early in the run.
“He got up on the gate before the start, so I was a little nervous we might not even get through the race,” Potter said with a laugh.
“But once we were in front, I was confident he’d run a nice race.”
And run he did.
Mad Punta dictated terms from the mobile, rating perfectly in front and never letting the chasers into it for a storied finish.
Potter shared the milestone with another driver, as fellow young gun Sean O'Sullivan remarkably also secured his 100th career win at Echuca on Tuesday night.
The budding reinswoman has come a long way from her first win in the sulky, bred by her dad Wayne - and now, with her ton on the board, Potter is looking ahead with quiet determination.
“I’m getting a few drives, which is really great, and I’ve got a couple of horses in my name as trainer, so I do that as well,” she said.
“(The plan is to) just keep going as it is at the moment.”
