Lionel Messi became the all-time leading goalscorer at the World Cup as Argentina beat Austria 2-0 in Dallas, confirming his side's place in the knockouts.
After an unfathomable missed penalty early on, Messi latched onto a Thiago Almada cutback to make tournament history with a first-time finish after half an hour.
Ralf Rangnick's men struggled for quality in the second half before a stoppage-time break saw Messi have an effort blocked, before he tucked home his 18th in tournament history.
With two wins from two games, Argentina are now highly likely to win Group J, although that is not yet confirmed mathematically.
Should they claim top spot, they would head for Miami, home of Lionel Messi's current club, for a last-32 game on Friday, July 3.
They would face the runner-up from Group H, which could yet be any one of the current leaders, Spain, Uruguay, Cape Verde, or Saudi Arabia.
In the unlikely event that Argentina drops to second, they would play a day earlier in Los Angeles against the Group H winner.
