Colombia won the match 0–2 with first-half goals scored by Cristián Zapata and James Rodríguez. United States' manager Jürgen Klinsmann stated that he was "pleased" with the performance of his team, he also saw the penalty as the "major point of the game", a remark to which American player Clint Dempsey agreed. Colombia's manager José Pekerman recognized the competitiveness of their rivals, but commented that "we could have scored a couple more."

Costa Rica vs Paraguay
The two teams had met in eight previous occasions, the last being a friendly in the Costa Rican national stadium on March 2015, resulting in a scoreless draw. In Copa América, both teams faced once, in a 2004 group stage match, won by Paraguay with a late penalty kick goal scored by Julio dos Santos.

Just as their previous friendly meeting, the game ended in a scoreless draw. Costa Rican manager Óscar Ramírez commented that it was "a two-faced match" and that "I would say we have lost two points". Paraguay's manager Ramón Díaz also though that his team lost two points; he was also critical of the hour chosen for the game, commenting that "I would like to take the actual protagonists, the players, in consideration".

Costa Rican player Kendall Waston was shown the red card in the stoppage time after a tackle against Nelson Valdez, becoming the first player to be sent-off in the tournament. Regarding the incident, Waston commented, "when I saw the red card I felt the world coming over me, because this tournament is very short and we all want to play".
