Argentina wing Manuel Montero scored a late try to earn the Pumas a 23-20 victory over France in Cordoba on Saturday.
The Pumas had to come from behind to beat France as they trailed 14-at at half time.
Debutant Manuel Montero scored a late winning try for Argentina on Saturday, which narrowly defeated France at the Mario Kempes stadium.
France had the better possession, but mistakes handed Argentina a try in each half, while France could only manage one try.
France haven't won a game in Argentina against Los Pumas since 1998, but will get a chance in the final game of its two-game tour on June 23 in Tucuman.
Both sides were using the game as a chance to experiment with their starting lineups, with each fielding two debutants from the start.
It was Montero who made the key play of the game.
He chased down a kick forward in the 77th minute, took the ball under control and avoided two tackles to make it 21-20 to the home side.
For France, it was a third successive defeat after a 24-22 loss to England and a 16-9 beating by Wales in the Six Nations earlier in the year.
Argentina, who defeated Italy 37-22 last weekend, will face France again next Saturday in Tucuman
