Even with a group of many irregulars, Mexico cruised to a 3-1 victory on Sunday against El Salvador.
El Tri found the back of the net after eight minutes when Hedgardo Marín scored, before El Salvador equalized two minutes later.
Goals from Elias Hernandez and Orbelín Pineda gave Mexico the lead to take early control of Group C.
Meanwhile, a pair of second-half finishes from Romario Williams and Darren Mattocks helped pace the Reggae Boyz to their first victory in the group stage.
Group C action continues on Thursday when El Salvador takes on Curacao and Mexico meets Jamaica.
Jamaica 2-0 Curacao
Mexico 3-1 El Salvador
