Alejandro Flores and Mark Rubalcava added one goal each for the Mustangs, who used four goals in the second half to break the match open.
“Our possession was really good,” Andres Jimenez said. “We were going too quickly in the first half, and (coaches) told us to slow it down a bit, and we did.”
Carlos Jimenez and Gaspar Figueroa added one assist each for Gilroy.
Mustangs goalkeepers Carlos Jimenez and Angel Velasquez combined on the shutout.
“I think I’m more impressed with the shutouts than the goals,” Gilroy coach Armando Padilla said. “In the second half, the kids got adjusted to the pace, and we went on a scoring spree.”
