If the Copa America Centenario needed a game to truly set pulses racing, Mexico's 3-1 victory over Uruguay in Group C on Sunday at University of Phoenix Stadium provided it.
Goals from Rafa Marquez and Hector Herrera in the last five minutes stole the points for Mexico in front of 60,025 fans, with both teams ending the game with 10 players.
An own goal from Alvaro Pereira handed Mexico the lead in the fifth minute, with Diego Godin equalizing for Uruguay in the 74th to set up a tense finish.
The hard-fought victory for Mexico moves it top of Group C and extends coach Juan Carlos Osorio's winning start as El Tri coach to eight victories.
Mexico will face Jamaica on Thursday, June 9 in Pasadena, while Uruguay take on Venezuela in Philadelphia on the same day.
Josef Martinez slotted a left-footed shot under goalkeeper Andre Blake in the 15th minute and Venezuela beat 10-man Jamaica 1-0 in their Group C opener.
Martinez's goal was set up by a Jamaican giveaway on a clearance attempt. Venezuela defender Rolf Feltscher intercepted and started a quick-hitting, four-pass combination that freed Martinez near the left corner of the six-yard box.
Jamaica midfielder Rodolph Austin was sent off in the 23rd minute, receiving a straight red card for a studs-up tackle on Venezuela's Tomas Rincon.
Michael Hector nearly tied it for Jamaica on a right-footed shot that hit the post in the 49th minute, and Blake had a diving save in the 70th minute to keep the deficit at one goal.
