Super featherweight
On October 2, 1982 Solis won the "Fecarbox"(Central American Professional Boxing Federation) Super featherweight title, knocking out Aquilino Asprilla in the 6th round. On November 18, 1983, he challenged Héctor Camacho for the WBC's world Jr. Lightweight title. In what was the second time two Puerto Rican fighters fought each other for a world title (the first time was Benitez vs. Santos in 1981), Solis lost to Camacho by knockout in round five at Roberto Clemente Coliseum.
