Lautaro Martínez scored from a rebound in the 88th minute, giving defending champions Argentina and Lionel Messi a 1-0 victory over Chile on Tuesday night that guaranteed a berth in the Copa América quarterfinals.
Messi's corner kick led to a shot blocked by goalkeeper Claudio Bravo, and Martínez pounced to score his second goal of the tournament on Argentina's 21st shot of the match.
Players stood and waited for three minutes while the goal, Martínez's 26th for the national team, was confirmed in a video review.
Argentina leads Group A with six points, followed by Canada with three, and Chile and Peru with one each.
