Triple-A team left without an MLB parent. They won back-to-back division titles in 2013 and 2014 under manager Wally Backman, but were eliminated in the Pacific Conference championship series on both occasions. In 2017 the 51s became one of the first teams to participate in the Copa de la Diversión initiative and for selected games played as the Reyes de Plata ("Silver Kings"). The name was a nod to Nevada being the "Silver State" and a homage to the contribution migrant workers made to the mining industry of Nevada.
