On Saturday night, Sergio Martinez beat Matthew Macklin by a technical knockout at Madison Square Garden in New York to remain the world middleweight champion.
But Macklin, 29, took great credit from the fight, providing Martinez, who is the linear world champion at the weight, with the toughest test of his reign so far.
The Birmingham fighter made life continually uncomfortable for the Argentinian, trading heavy blows what for the most part was an even contest, but he was knocked down twice in the 11th, causing his camp to withdraw their man.
Macklin, who, as the son of Irish parents had great support on St Patrick's Day, felt he was in control for much of the fight.
He said on Sky Sports 1: "I thought I had the most momentum, I thought I was in the driver's seat. Some of the rounds were close but I thought I was dictating.
"I was the one that was boxing to the game plan, and I was taking him out of his."
Macklin explained he took a more considered approach to the fight than usual.
He said: "Putting reckless pressure on would have been detrimental so I tried to feint, move my head, box, take him out of his rhythm, upset him a little bit and ease my way into the fight, then start putting the pressure on."
The tactic was a good one and some observers had him level or even ahead once the glove of Martinez, the heavy favourite with bookmakers, touched the canvas in the seventh round.
Thereafter though it was all about the 37-year-old, who upped his game and dominated from then.
Asked what changed in the later rounds, Macklin said: "I switched off a little bit upstairs, stopped moving my head a little bit.
"It wasn't extreme fatigue because it wasn't that sort of fight but I certainly slowed a little bit, stopped moving my head, got a bit heavy on my feet and he caught me square a few times.
"That allowed him to get his confidence up and get into his rhythm."
That rhythm saw Martinez send him to the canvas in the 11th.
Macklin got up, but soon found himself sprawling again.
The count reached eight as the bell went and, though Macklin wanted to continue, his camp asked the referee to call a halt.
"I've never ever quit," said Macklin. "I wanted to continue. I gave it 100%. I think anyone who watched would agree. Hopefully I didn't let anyone down."
