"Carlos Zambrano returns to the mound for the first time in nearly three months Sunday, auditioning for his next boss.

Zambrano officially signed a contract Saturday to pitch for Los Caribes de Anzoátegui in the Venezuelan Winter League, and he'll start Sunday in Valencia, Venezuela, facing Navegantes del Magallanes."
