The 1,000m time trial was making it's debut at these Games and featured a mix of sprinters and endurance athletes for this halfway-house event.
Then came the girl from Carmarthen.
Buoyed by the crowds, Finucane set the pace, clocking one minute 05.285 seconds which guaranteed a bronze medal, with just two left to ride.
Neither England's Sophie Capewell nor New Zealand's Olympic sprint champion Ellesse Andrews were able to match that mark.
You'd imagine that winning a new event would require a lot of practice and a specific plan.
Not for Finucane.
"It was the unknown," she said.
"I went into it not knowing what I could do because I'd never really done one before. I just had to hurt myself as much as I could, and I did.
"I'm not sure I'll be doing one of them again!"
It seems that there is nothing Finucane cannot do.
Only weightlifters David Morgan and Andy Phillips can match the 23-year-old's achievements at a single Games, when they both won three golds in Auckland in 1990.
And Finucane has one more race to come.
"I came into these Games wanting to win a gold," she said.
"To do it three times, I did not think would happen to me.
"I just can't believe I'm living this life at the moment. I've got one more event, so we'll just see what I can do."
Should Finucane repeat the feat in Sunday's women's keirin, she would become the most successful Welsh woman in Commonwealth Games history, taking the two-day old title of Para-athlete Olivia Breen.
The sprinting superstar has an endurance counterpart in team-mate Morris.
Once again at these Games the Welsh anthem reverberated around the velodrome twice in one night.
Prince Louis even got in on the act, donning a bucket hat with 'Beicio Cymru' - Welsh for Welsh Cycling - written on the front.
This time Morris had company on the podium, with Roberts stood beside her on the next step.
"This one was super cool," she said.
"We're team-mates and really close friends. We often room together, so to share that moment with her was just amazing."
The qualified doctor won gold on Friday and thought she had won silver too in the women's scratch event before she was relegated to fifth for entering the sprinter's lane when her opponent was already there.
There was no such bad luck today.
She bossed the race from start to finish and claimed her second gold.
“It felt like a hard race to be honest," sad the World champion.
"It feels like a blur. I just know I was full gas to the line in that last sprint."
Roberts clung on to second, picking up two points on the last lap to hold off Australian bronze winner Georgia Baker, who was just one point back.
This was her first individual medal after collecting team pursuit bronze alongside Morris, Megan Barker and Ciara Oliva on Thursday.
"Incredible," she said, when asked how she was feeling.
"To get an individual medal as well, that makes it even more special.
"I'm so surprised but really happy."
Wales’ success on the track has not been without incident and tonight was no different.
On Thursday, 18-year-old Ioan Hepburn pulled out of the bronze medal race on the start line of the men’s team sprint with an illness.
We also had Morris’ silver success taken away when she was relegated off the podium on Friday.
Saturday saw drama in Ball’s men’s tandem B sprint final.
He and pilot Rotherham lost the first of three races to Neil Fachie and Aaron Pope when the home favourites caught them by surprise with an early attack.
The Welsh pair clawed their way back to force a decider.
After an unconventional start, where both flew out the gates, there was a coming together on the back strait which saw Fachie and Pope sprawled on the Serbian pine.
The raucous arena fell eerily quiet before they rose to their feet and dusted themselves off.
Battered and bruised, the Scots roared home in the restarted race, with Wales ruing what might have been.
“It's pretty raw right now, I'm not going to lie," said Ball.
"We knew we had a job to do. Obviously, we were buzzing off the second round win but it didn't go our way."
Pilot Matt Rotherham felt Wales were denied an opportunity.
"We took position one, we were in control of the race," said Rotherham.
"And then I feel like Scotland rode into us and knocked themselves off.
"To my mind, they caused the incident and we should get first choice of the position we want to be in when we come to the restart.
"We weren't given that opportunity.
"It's like all our advantage and all our tactical opportunity got taken away by no fault of our own and by the fault of our opponents."
A second crash of the night occurred in the evening's final race, the men's 10km scratch.
Several riders received treatment in the aftermath though Welshman Rhys Britton walked away relatively unscathed.
"I'm more disappointed than anything to be honest with you," he said.
"Just a few splinters and burns but I came off alright, my bike didn't come off that well.
"I think it was a good chance of a result and just a bit of wrong positioning just took me out of the race."
