Kellie Harrington made a winning return to the ring on Tuesday as she defeated Sweden's Agnes Alexiusson in the 73rd International Strandja tournament in Sofia.
It was the Dubliner's first bout since her Olympic gold medal success in Tokyo last summer.
Four of the five judges in the Bulgarian capital had Harrington winning all three rounds of the last 16 bout, while the Estonian official gave Alexiuusson one round.
Harrington won via unanimous verdict and advances to the quarter-finals of the tournament.
She was the first of six Irish boxers in action on Tuesday before Waterford fighter Kelyn Cassidy lost 4-1 split to Finland’s Nikita Nystedt (30-27, 29-28, 28-29) in their men’s heavyweight (80kg) bout.
Michaela Walsh also returned to action for the first time since the Olympics on Monday and defeated Lacramioara Perijoc of Romania in a 57kg bout via unanimous decision.
