La Serena, Chile: Sergio Aguero reignited Argentina's Copa America challenge here Tuesday, scoring the only goal as the favourites defeated historic rivals Uruguay 1-0 in a hard-fought first round clash.

English Premier League star Aguero headed home a cross from Manchester City team-mate Pablo Zabaleta in the 56th minute to settle a gritty encounter that leaves the Argentines on pole to win Group B. Uruguay's defeat means the 2011 champions must now beat Paraguay in their final group game to be certain of clinching a place in the last eight, although they could still reach the knockout rounds as one of the best third placed teams.
