Kenny Egan's southpaw skills consigned Sunderland's Tony Jeffries to an Olympic bronze medal after their light heavyweight semi-final in Beijing.
The Irishman was always on top and built on an early lead to eventually triumph 10-3 and book a place in Sunday night's Olympic final.
Earlier Sutherland's Ireland team-mate Paddy Barnes was unhappy with the judging after being comprehensively beaten 15-0 by Chinese superstar Zou Shiming in the light-flyweight semi-finals.
Despite exceeding expectations simply by qualifying for the Games, the 21-year-old from Belfast was furious with the scoring of his contest and not content with his bronze medal.
Barnes said: "I got beat fair and square but the judging was terrible.
"There's no way I lost 15-0. I hit him with clean shots. The way the judging is out here, it should be the judges being drug-tested, not the fighters.
"I don't care about the Olympic medal. They can keep it for all I care. Bronze is for losers."
David Price will also have to settle for Olympic bronze after being stopped with 50 seconds remaining in the second round of his bout with Italian Roberto Cammarelle.
Price never got into the contest and was consistently caught by the world champion's right hand which helped him establish a 9-0 lead by the time of the stoppage.
The referee intervered to wave the contest off when a right left Price sitting in the tropes and clearly unable to continue.
