Veyre, who struck gold on home soil at Toronto 2015, made light work of Costa Rican boxer Maria Isabel Perez at the Coliseum Nacional de Ingenieros in the Honduran capital.

The 28-year-old Canadian impressed throughout and got the job done by virtue of a unanimous points decision.

Mikaela Mayer of the United States got her pursuit of the lightweight gold medal off to a winning start as she also reached the next round.

Mayer, a World Championships bronze medallist in 2012, outclassed Mirquin Jahaziel Sena of the Dominican Republic.

The 26-year-old from Los Angeles secured a unanimous victory as all five judges scored the bout in her favour.

Mayer was not the only American boxer to win on the opening day of the competition as Virginia Fuchs booked her place in the next round of the women's flyweight category.

Fuchs, a multiple National Championships silver medallist who reigned supreme at last year's Olympic test event in Rio de Janeiro, proved too strong for Brazilian opponent Grazieli Jesus de Sousa with a comprehensive 5-0 success.

Veyre's compatriot Kim Clavel had earlier emerged triumphant from the opening bout of the Championships as she beat Esther Mario Santizo of Guatemala in their light flyweight encounter.

Clavel had to battle for her place in the second round and narrowly prevailed by split decision.

Three of the five judges judged her to be the winner of the fight but two had favoured the Guatemalan.

As well as gold medals, competitors at the AMBC American Confederation Championships are also vying for places at the men's International Boxing Association (AIBA) World Championships in Hamburg, which run from August 25 to September 3.

Action is due to resume tomorrow, with the event in Tegucigalpa due to conclude next Sunday (June 18).
