The Baggies have confirmed they will return to America this summer following the success of their last visit.
Bryan Robson's men will spend nine days in southern California with two games lined up against MLS opposition.
They will take on Los Angeles Galaxy on Wednesday July 20 and Club Deportivo Chivas on Tuesday July 26.
The players will also be put through their paces at the US Soccer Federation's national training centre.
Robson will hope the trip proves as successful as the bonding exercise in Florida last February which proved a key exercise in re-igniting Albion's season.
