The Ostioneros de Guaymas were a professional baseball team based in Guaymas, Sonora, Mexico. The Ostioneros played in the Mexican Pacific League and used the Estadio Abelardo L. Rodríguez as their home ballpark. During its existence, the club won seven league championships.
The Ostioneros were one of the four original founding members of the Mexican Pacific Coast League, a winter league circuit that operated in Mexico in the seasons from 1945–46 through 1957–58.[1] The team won pennant titles in the 1947–48 and 1950–51 seasons, managed by Juan Guerrero and Luis Montes de Oca, respectively.[2] In 1950–51, Ostioneros shared the league championship with the Tacuarineros de Culiacán.[3]
Before the 1958–59 season, the circuit was renamed Sonora Winter League and lasted through the 1991–92 season.[1] This is considered the beginning of the modern era of what is now the Mexican Pacific League. The Guaymas club also competed in this second stage, winning titles in 1958–59 and 1959–60 guided by Manuel Magallón, in 1962–63 and 1964–65 with Guillermo Frayde at the helm,[4] and 1967–68 with Ronaldo Camacho, to won seven league titles in both stints.[2]
The Ostioneros played at the Estadio Abelardo L. Rodríguez during its entire existence.[5]
The Ostioneros name has since been used by other sport clubs based in Guaymas.
