Corona did not play in Wednesday's semifinal against Honduras, but he has two goals in the tournament so far. He scored in the 5-1 victory over El Salvador in the quarterfinals and also in the 4-1 victory over Cuba in the group stage.
Eddie Johnson started up front with Corona, Stuart Holden, Landon Donovan, Alejandro Bedoya and Kyle Beckerman in the midfield. Michael Parkhurst, Clarence Goodson, Matt Besler and DeMarcus Beasley form the back line in front of Nick Rimando.
Mix Diskerud came on in the 23rd minute after Holden left with a knee injury.
Holden knocked his left knee midway through the first half, but grabbed his right knee after he hit the ground. Trainers worked with him briefly on the field before he got off and walked to the sideline, where they continued to work on him. He eventually walked to the locker room.
Holden missed almost 2½ years because of injuries to his right knee. He initially injured it against Manchester United on March 19, 2011, returned from surgery to play in a League Cup match that September, then had another operation on the same knee eight days later.
Panama coach Julio Dely Valdes left his lineup unchanged from his team's 2-1 upset of Mexico in the semifinals.
The Americans will not have Klinsmann on the sideline as they seek their fifth Gold Cup title. He is suspended for the game, the result of his tirade over officiating in the closing minutes of the semifinal.
