Toro advanced to the final at the Teodoro Palacios Flores National Gymnasium, where he faced United States' Ildar Hafizov.

Bronze medals were earned by Brazil's Calebe Correa and Mexico's Diego Martinez.

Jamal Johnson clinched gold in the men's 72kg event, as the American won all three bouts of a round robin format in the weight division.

Mexico's Juan Ruiz finished as the runner-up, with Guatemala's Carlos Fuentes receiving the sole bronze medal on offer in the division.

A closely contested men's 63kg final was won by Ecuador's Andres Montano, who edged out American wrestler Randon Miranda 7-6.

Guatemala's Emerson Ordonez rounded off the podium places by winning the bronze medal contest 5-4 against Peru's Joao Benavides.
