The United States continued their domination of the Pan-American Wrestling Championships as they won five gold medals from a possible seven on the second day of competition in Buenos Aires.

They finished the Greco-Roman bouts with another two victories at Tecnopolis in the Argentine capital.

Former under-20 world champion Kamal Bey got the US off to a winning start as he edged out Cuban Yosvanys Peña Flores in a tense 2-1 battle in the under-77-kilograms final.

The pair traded positivity points with the triple continental champion Peña Flores scoring first.

Halfway through the second frame, he challenged a call from the judges that failed and resulted in the crucial second point for Bey.

Colombia's Jair Cuero and Wuileixis de Jesus Rivas of Venezuela joined them on the podium with the bronze medals.

Bey's compatriot Spencer Woods won a four-man round-robin competition in the under-82kg class.

Of his three wins, two came from tech falls and the other via an injury default.

Jose Mosquera of Colombia and Canadian John Yeats made up the top three in second and third, respectively.

The final Greco-Roman title, in the under-87kg tournament, went the way of Cuba's Daniel Gregorich who earned his third gold at the Championships following an injury withdrawal from Venezuela's Luis Avendano.

Another Colombian bronze was sealed courtesy of Carlos Muñoz while the US' Alan Vera stood with him in joint-third.

The women's wrestling competitions began on day two, with three of the four winners being World Championships medallists.

Reigning senior, under-23, and under-20 world champion Amit Elor of the US made her debut in the continental event in the under-72kg competition.

She got the better of Colombia's Luisa Mosquera and Katie Mulkay of Canada in the round-robin tournament as they settled for silver and bronze, respectively. 

Another round-robin triumph went to American Mallory Velte in the under-65kg.

It marked the 28-year-old's second Pan-American Championships win as she defeated second and third-placed Paula Montoya of Colombia and Canadian Aleah Nickel.

A third women's gold for the US came courtesy of Xochitl Citalli Mota Pettis in the under-59kg.

Canada's Alexandria Town clinched the silver medal with a win against the weight category's only other competitor, Jessica N Derell of Barbados.
