On the other, you had Ender Inciarte, David Peralta and Miguel Montero rooting for the Little League team from their native Venezuela.
Perez has been closely following the Guadalupe Linda Vista team from the outset and was excited by their 11-1 win over the team from Venezuela.
"It's a great experience for those kids," Perez said. "They get to come to this country and see things and get to meet other kids from all over the world."
Inciarte paid close attention to the team from Maracaibo, Venezuela, because he has a cousin on the team.
