An early goal by Lautaro Martinez and Sergio Aguero's late second gave Argentina a 2-0 win over Qatar on Sunday that qualified them for the Copa America quarter-finals.
Already-qualified Colombia beat Paraguay 1-0 in the other Group B match to secure a place in the last eight for both Peru, who finished third in Group A, and Uruguay, currently second in Group C.
Argentina, who finish second in Group B behind Colombia, will play Venezuela at Rio de Janeiro's iconic Maracana stadium in the quarter-finals, while tournament debutants and guests Qatar are out.
Paraguay, on two points, must wait and see what happens in Monday's Group C clash between Japan and Ecuador before finding out if they qualify as one of the two best third-place finishers.
Peru, with four points, are sure of that while only a draw between Japan and Ecuador would see Paraguay progress.
Argentina coach Lionel Scaloni recalled Manchester City forward Aguero for the crunch tie while Martinez kept his place at the expense of Angel Di Maria.
Asian champions Qatar made a calamitous start when a weak headed clearance from Tarek Salman fell to Martinez 12 yards out, but the Inter Milan forward sent his volley over the top.
He didn't have to wait long for another chance though as Bassam Hisham played a ball across his box and straight to the feet of the Argentina forward, who scuffed a shot into the bottom corner after just four minutes.
"The goal came early and that allowed us to approach the game with greater calmness," said Martinez.
"There was pressure, we had to win to progress and we're happy. Now we have to work hard."
"We played a great team that knew they had to win, they took their first chance really well. It was our mistake."
- Aguero industry rewarded -
