The victory on Sunday gave Mexico a record fifth Gold Cup title and was their first victory away to the US since 1999.
After having the better of the opening half, the US fell behind in the 56th minute when Tottenham midfielder Giovani Dos Santos went down under challenge from Jay Heaps and Jamaican referee Courtney Campbell awarded a penalty.
Mexico skipper Gerardo Torrado confidently beat keeper Troy Perkins with the spot kick and the Americans, who have fielded a second strength team in the tournament, promptly fell to pieces.
Santos goes to town
Dos Santos, in inspirational form, made it 2-0 and provided the pass to substitute Carlos Vela for the third.
Arsenal striker Vela, who had transformed the game after coming as a half time substitute, then set up Jose Antonio Castro for the fourth and the US misery was compounded when defender Heaps was sent off in the 88th minute for a second yellow card.
In-stoppage time Guillermo Franco struck the fifth for Mexico with the US defence all at sea.
The two are due to meet again on August 12 in a World Cup qualifier at the Azteca Stadium in Mexico City.
