Argentina held off a late rally to beat South American rivals Brazil 82-77 and make it to the semi-finals of an Olympic Games for the third straight time.
In a re-match of the FIBA Americas Championship final won by Argentina last year, they looked comfortable when Manu Ginobili's three-pointer gave them an 70-59 lead with seven minutes left to play.
But Brazil had other ideas. The outstanding Marcelinho Huertas added two points from the free-throw line to start a 9-0 charge that got it to 70-68 on Alex Garcia's lay-up.
Leandro Barbosa took advantage to slice the lead back to 74-71 with less than two minutes to go.
