Valeri opened the scoring in the 28th minute, volleying a cross from Jorge Villafana past goalkeeper David Ousted for his ninth goal of the season.
Adi scored his seventh and eighth goals of the season in the second half. The first came in the 66th minute, after Valeri's steal and pass gave sent Adi in one-on-one on Ousted. Adi struck again four minutes later off Darlington Nagbe's assist.
