SALTILLO, Mexico (AP) -- Josuan Hernandez hit a grand slam in the sixth inning, leading the Saraperos de Saltillo to a 15-6 win over the Tecolotes de los Dos Laredos on Sunday.
The grand slam by Hernandez scored Christian Zazueta, Juan Perez, and Rainel Rosario to give the Saraperos a 13-3 lead.
Santiago Gutierrez (1-0) got the win with 1 1/3 innings of scoreless relief while Dos Laredos starter Luke Heimlich (0-1) took the loss in the Mexican League game.
Saltillo took advantage of some erratic Dos Laredos pitching, drawing a season-high seven walks in its victory.
Balbino Fuenmayor homered and singled twice, scoring three runs for the Tecolotes.
