Joe Calzaghe taught 'Contender' star Peter Manfredo a violent lesson in the reality of world championship boxing with an emphatic third-round stoppage victory at Cardiff's Millennium Stadium.
Calzaghe successfully defended his WBO super-middleweight title for the 20th time, an accomplishment which saw him equal the records of fellow greats Larry Holmes and Bernard Hopkins.
In front of a record indoor crowd of around 35,000, Calzaghe blazed out for the third round and rained a seemingly endless supply of hooks down upon hapless Manfredo.
Watching closely as the 26-year-old challenger gamely attempted to stay on his feet, referee Terry O'Connor had finally seen enough at one minute 30 seconds of the round and waved the contest off.
While such a quick win had always been expected for Calzaghe, of equal importance was its manner which cannot fail to have impressed his influential paymasters on both sides of the Atlantic.
In truth, having starred in the first series of the popular US reality TV boxing show, Manfredo had come to Cardiff with a broadcast appeal far outweighing his pure boxing credentials.
Successive knockout wins over Scott Pemberton and Joe Spina just about earned him his shot but few if any outside his camp gave the Providence native a realistic shot.
At least Manfredo went out on his feet, but the manner of Calzaghe's win underlined that the 35-year-old belongs in a different league to almost all the current crop of 12-stone contenders.
One exception is unbeaten WBA champion Mikkel Kessler, the Dane who has also been promoted by Home Box Office and would certainly pose a sterner test in a possible super-fight to come.
Despite Manfredo's questionable qualities, this was a clever fight for Calzaghe, designed to impress an American audience granted a rare free-to-air glimpse of the Welshman via the Home Box Office network.
And the challenger played his part too in the opening round, scoring with a clean right hook and largely keeping the champion at bay with his strength whenever he came into range.
Calzaghe dug home a couple of hurtful right hooks to the body at the start of the second and continued to flick jabs through Manfredo's guard as he began to take control of the fight.
The champion seized upon his advantage early in the third, cracking home a magnificent right to tee up a sustained period of punishment which had Manfredo desperately seeking to maintain his guard.
Scenting another dramatic quick win, Calzaghe blazed away with both hands, and the intervention of O'Connor was not unduly protested by the Manfredo corner.
Earlier on the bill, Amir Khan made a big impression on his American television debut with a crunching third round stoppage victory over Doncaster's Steffy Bull.
The 20-year-old from Bolton was barely troubled by his experienced opponent and a barrage of unanswered blows dumped Bull to the deck and ended the contest after one minute 45 seconds of the round.
