Savannah Marshall was left exhilerated after launching her professional career with victory on the biggest show on earth.
The Hartlepool boxer was sent out first at the T Mobile Arena in Las Vegas which was staging the cross-code the Floyd Mayweather-Conor McGregor confrontation.
And the 26-year-old did not disappoint, as she clinched a unanimous four-round points success over Sydney LeBlanc.
Marshall, who had not boxed for 12 months, when she suffered a controversial points to Nouchka Fontijn in the Olympic Games quarter-final, showed no signed of ring rust against her 33-year-old opponent.
The ex-Headland ABC star, cheered on by parents Christine and John and a number of Hartlepool fans, showed her skill and authority from the first bell to control matters against the American hardcase.
"I felt brilliant," said Marshall.
"She was really tough like I knew she would be. I'm glad that I got out of there with a win against a top class opponent."
Marshall, who had Headland coach and mentor Tim Coulter in her corner, displayed no nerves on the big stage.
"I've been looking forward to this all week so I'm really excited about my performance," said the 2012 world amateur Champion, who had been trained in the UK by Peter Fury in Bolton and in the Northgate gym by John Stubbs and Tim Coulter, who was in her corner tonight.
"The build-up this week has been great."
LeBlanc came into the contest with a winning record and the boast of having taken double Olympic gold medallist and new IBF and WBC world champion, Claressa Shields, the distance this year.
Marshall, guided excellently by Coulter, produced a disciplined and dominant display to win on the scorecards of all three judges.
"I knew it would be hard to stop her so I made sure to box her," added Marshall. "I was able to execute my game plan. I'm happy with how I performed."
