Torres has appeared in three editions of the CONCACAF Gold Cup (2005, 2007, 2009) and his presence is a boost to Julio Dely Valdes' squad, which is preparing for the 2013 UNCAF Copa Centroamericana to be held in Costa Rica, January 18-27.
With the addition of Torres, Panama now has four foreign-based players in the selection, including: Rolando Blackburn (FK Senica, Slovakia), Jaime Penedo (Municipal, Guatemala) and Blas Perez (FC Dallas, United States).
The national team returned to training on Wednesday after a short break for the New Year, holding two sessions per day.
On Saturday, the Canaleros have scheduled two preparation games. In the morning, they will play 90 minutes against Tauro FC and, afterwards, will meet Sporting SM in a 45-minute match.
Panama, which won its only Central American championship in 2009, was drawn into Group B in this year's Copa Centroamericana and will face El Salvador (January 20) and Honduras (January 22).
