The long-term injury to star striker Paulo Wanchope gave Parks the opportunity to impress in the friendly against Japan earlier this year.
The Udinese man seized the chance with both hands, hitting a 77th-minute equaliser less than 10 minutes after coming on as a substitute.
Manager Alexandre Guimaraes now knows he has another option up front and should any of his first-choice strikers become unavailable in the tournament then he can rely on Parks.
