The Olmecas won their only Mexican League championship in 1993 under manager Juan Navarrete.

The team included Arturo Bernal, Rommel Canada, Joel Orquendo, and Nike Nagy.

As the 1980s began, the Plataneros signed stars Luis Tiant and Jesus Sommers but did not find success on the field.

In 1987, they signed Steve Howe, who was attempting a return to the major leagues after a drug suspension.

In 1993 Juan Navarrete took over as manager and the club signed many foreign players including Rafael de Lima, Alexis Infante, Rusty Tillman, and Todd Brown.
