Rodriguez struck in the eighth minute with a delightful chip over goalkeeper Augusto Batalla after a counter-attack. He then made it 2-0 from the penalty spot after being brought down by Ignacio Canuto here on Friday, reports Xinhua news agency.
The 33-year-old, who earned a sole Argentina cap in 2009, struck his third goal with a sublime volley into the top left corner after a failed clearance.
The result at the Monumental stadium lifted Atletico to 11 points from five matches, one point ahead of second-placed Racing Club, who have a game in hand.
In Friday's only other match, Matias Pisano and Cristian Chavez netted second-half goals as Aldosivi jumped to fourth in the 26-team standings with a 2-0 win at Estudiantes.
