Sam O'maison's did his growing reputation the power of good tonight.
The Shiregreen, Sheffield southpaw brutally knocked out Durham leftie Anthony Hardy only seconds into the first round, on a Dennis Hobson show at the Magna Centre, Rotherham.
The headline fight didn't start until 11.15pm, but the style of his victory was worth waiting for.
The 24-year-old Ryan Rhodes fighter sparked his slightly younger rival out with a clean blow to the chin.
Officials were soon in the ring to ensure the north east man was not seriously hurt.
It was an explosive end to a four-hour show which was briefly interrupted by crowd disorder.
The evening included a winning return to the wing, also, for another fancied Sheffield boxer, Waleed Din.
He had lost a Commonwealth title fight at the same venue last year, but outpointed Bulgarian Stefan Slavchev.
Dom Ingle-trained flyweight Kyle Yousaf also had a comfortable victory over 41-year-old veteran Sergey Tasimov.
Meanwhile in Northern Ireland, Rossington super featherweight southpaw Maxi Hughes shocked the home crowd with a win over James Fryers in Belfast.
The 25-year-old won on a split decision, earning the right to be the mandatory challenger for the British title held by Liam Walsh.
