The 6ft 8in powerhouse did not skip a beat in front of his home support at the historic Aintree Equestrian Centre, after putting on a clinical and almost faultless performance.
The 2008 Olympic bronze medallist dominated right from the start, utilising a solid, rangy jab to force Sexton on the back foot. Price was looking to pick Sexton apart, finding gaps in the Norwich man’s defence to land crisp uppercuts and body shots.
Sexton, however, did try to get himself into the fight in the second but it was to no avail as Price remained disciplined and repeatedly found the target, with Sexton offering little in return.
The third round was slightly better for Sexton as he bombed forward in an attempt to unsettle the 28-year-old behemoth. However, Price stayed strong and a right hook clipped Sexton on the temple sending him down on one knee.
The former Commonwealth champion was saved by the bell but it was only a matter of time before Price finished him off.
Sexton was immediately on the receiving end of Price’s onslaught at the beginning of the fourth, as Price scored another knockdown with a flurry of shots.
Sexton rose to his feet yet again but Price responded by flooring Sexton with a mammoth right hook that sent Sexton crashing hard to the canvas.
Referee Howard Foster had absolutely no choice but to wave the fight off and declare Price the victor.
Speaking after the fight, the new champion said: “It’s everything I’ve worked towards since I turned professional.
“This was the first target. It’s done. Now we can move on.
“I felt like I boxed the perfect fight. I don’t think Sam Sexton laid a glove on me. I knew when I started getting through I’d hurt him.
“I knew I’d have to be patient, but I’m ready to step up and face the best out there.
“I won’t rush – I’m not the finished article yet – but I believe a world title is my destiny. This feels like the end of the beginning.”
His promoter, Frank Maloney, added: “David has the best jab since Lennox Lewis as a heavyweight. That was a 10 out of 10 performance.
“We’ve now got someone who I believe will bring the world heavyweight title back to Britain. He is a credit to British boxing.”
Price is now almost certain to be earmarked as a future opponent for the Klitschko brothers, who between them hold the four main world heavyweight titles.
However, Price himself has admitted that he is not quite ready to face the Ukrainian kingpins, who will seek to rush Price before he is truly ready.
Sexton, who only had two losses against Dereck Chisora coming into the fight, was by no means an easy opponent but was made to look far inferior to the Liverpudlian giant.
Price’s stock will now continue to rise as he know looks head and shoulders – literally – above the rest of Britain’s heavyweights.
