Callum Johnson needed just 77 seconds to stretch his unbeaten professional record to 12 bouts.
The Boston boxer beat Jose Manuel Iglesias by knockout in lightning quick time at Leeds’ First Direct Arena on Saturday night.
The tall Iglesias went into the bout having never been stopped in the pro ranks, but Johnson had sent him to the canvas twice before the fight was ended in the first round.
“He had a good record going into the fight, he’d won eight and lost three and not been stopped before,” Johnson said.
“Plus he’s 6’5”, which made it look like I’d be in for an awkward night.
“But I caught him well.
“I don’t want to sound big headed, but if I whack someone square on the chin they’ll probably go down as I’ve got a good whack on me.”
Johnson’s display certainly impressed Eddie Hearn, whose Matchroom Sports company were promoting Saturday night’s event.
“I’ll hopefully be working with Eddie more and appear on a few more Matchroom shows,” Johsnon added.
“Nothing’s official or set in stone, but we’ve talked about it.”
Johnson’s past four fights have all been won within two rounds.
