Birtley boxer Pat McCormack settled for a silver medal after being outclassed in his welterweight final by Cuba's Roniel Iglesias at the Kokugikan Arena.
McCormack, who progressed to the 69kg showpiece after Irish opponent Aidan Walsh withdrew from their semi-final because of injury, was hoping to win Britain's first boxing gold of these Games.
However, all five judges preferred the slicker work of southpaw Iglesias, who won every round on three of the officials' scorecards.
