The 2017 world champion in the over 90kg weight division and Olympic over 75kg bronze medallist dominated the rest of the field to ensure a successful end to the Championships for the American team at Coliseo Deportivo.

Robles, who served a two-year drugs ban from 2013 to 2015, lifted 124kg in the snatch and 155kg in the clean and jerk to finish on an overall total of 279kg.

Dominican Republic's Verónica Saladín was second behind the American in all three disciplines as she totalled 270kg following a clean and jerk of 147kg and a snatch lift of 123kg.

Tania Mascorro of Mexico won bronze in the snatch thanks to a best attempt of 120kg and also in the overall having finished the event on 264kg.

Bronze in the clean and jerk went to Ecuador's Lisseth Ayoví on 146kg.

Crismery Santana of Dominican Republic, bronze medallist at last year's World Championships, took overall and snatch gold in the women's 87kg division.

Santana lifted 112kg in the snatch and 141kg in the clean and jerk to top the overall podium with 253kg.

María Valdés of Chile secured the clean and jerk title having produced a best of 141kg - the same managed by Santana, who lost out on a clean sweep by virtue of her higher bodyweight.

Valdés also earned silver in the snatch with 108kg and in the total as she ended 4kg shy of Santana's overall haul.

Jaqueline Ferreira of Brazil claimed bronze in the snatch, while Ecuador's Tamara Salazar was third in the clean and jerk and overall competitions.

There was further success for the US as Caine Wilkes clinched gold in the overall and clean and jerk in the men's over 109kg.

Wilkes hoisted 219kg in the clean and jerk and 182kg in the snatch to seal the title on 401kg, just 1kg ahead of Cuba's Luis Lauret.

Lauret's snatch of 183kg was enough for gold in the discipline, with Wilkes taking silver and Keiser Witte claiming bronze.

Witte was also third in the overall on 387kg, while Dominican Republic's Luis Coca won the clean and jerk bronze medal.
