American star Jeff Lacy sent out a chilling warning to Joe Calzaghe when brushing aside the challenge of Britain's Robin Reid in Tampa Bay, Florida.
Lacy, defending his IBF super-middleweight title for the third time, wowed his home-town fans by dominating a one-sided contest before Reid's trainer Bryan Hughes threw in the towel at the end of the seventh round.
Reid, a former WBC champion, had never been floored in a 43-fight career but was forced to touch down four times in this bout before being put out of his misery.
Sydney Olympian Lacy, aged 28, took his record to 20-0 with his 16th win inside the distance against an opponent who looked to have little left in the tank at 34.
And, providing Calzaghe comes through the 16th defence of his WBO crown in September, the American has no fear of giving up home advantage for their big-money unification clash in Cardiff on November 5.
"I train hard for each and every one of my fights," said Lacy.
"It doesn't matter if you put me in Kathmandu, I'll go anywhere and I'll be ready."
And his promoter Gary Shaw added: "First Saturday in November, Joe Calzaghe we're coming right to you in Wales. We'll be there ten days before - look for us!"
Reid had not fought for six months since a low-key points win over Ramdane Serdjane in Brentwood and showed clear signs of ring-rust early on.
The challenger was floored by an illegal low blow in the third and was also troubled by Lacy's left hook later in the round. The American's faster hands were allowing him to force the pace and Reid's problems continued when he was deducted a point for a headbutt in the fifth.
To add insult to injury, the British veteran was also given a disgraceful count after being caught on the break at the same time.
However there was no disputing a brilliant flurry of punches from Lacy that put him on the floor again as the bell loomed.
Reid just could not find the power to prevent Lacy from pushing forward and he was down once more in the sixth following a big overhand right from the champion.
Referee Jorge Alonso took another point off Reid for holding in the seventh before a stunning uppercut from Lacy sent him crashing to the canvas again towards the end of the round.
Reid just made it to the bell but trainer Hughes had seen enough and, despite protests from the fighter, called a halt to proceedings.
"Never doubt my punching power, never doubt my ability," declared Lacy.
"Robin coming here without ever being knocked down was a challenge I put before myself and stopping him was something I had to do.
"We had a good battle in there but I took his best shots and he couldn't take my best shots, and that was the difference in the fight.
"I grew stronger as the fight went on, while he was getting weaker."
There will no doubt be calls for Reid to retire, but he put a brave face on proceedings and claimed that referee Hughes had waved the contest over prematurely.
"Utmost respect to Jeff, he caught me with some good shots, but he didn't actually catch me clean," said the Runcorn fighter.
"The punches that he was catching me with were decent punches, there's no doubt about that, but I was looking to carry on.
"I was fine and I could have gone on.
"I don't think the fight should have been stopped.
"I admit I took a few shots but I caught him with some good shots as well and a couple of them hurt him."
