The Guaynabo Mets are a Puerto Rican professional basketball team based in Guaynabo, Puerto Rico, competing in the Baloncesto Superior Nacional (BSN), the island's premier basketball league, as part of its East Division. Originally founded in 1935 as the Cangrejeros of Santurce, the franchise relocated to Guaynabo in 1976, adopting the Mets moniker due to the city's metropolitan location. The Mets play their home games at Mario Morales Coliseum, named after Mets legend Mario "Quijote" Morales, a legendary player who guided the Mets to three BSN championships in the 1980s (1980, 1982, and 1989).
The Mets reached the finals in 1978, 1980, 1981, 1982, 1983, 1985, 1989, 1990, 1993 and 2021.
