Rio de Janeiro: A late Edinson Cavani header gave Uruguay a 1-0 win over defending Copa America champions Chile as the Celeste secured top spot in Group C.
In Monday's match, Cavani struck nine minutes from the end of a dour contest at the Maracana stadium in which both teams managed only three shots on target.
Chile opened brightly with Alexis Sanchez sending a shot over the crossbar and Charles Aranguiz seeing his long-range effort palmed away by Fernando Muslera.
But Uruguay grew in confidence and Georgian Di Arrascaeta had his team's first chance after receiving a Luis Suarez pass and then thumping an attempt from 25 yards into the stands.
Then it was Suarez's turn to miss an opportunity as he rounded Gabriel Arias, only to see the goalkeeper recover to turn the Barcelona forward's shot behind for a corner. Uruguay continued to press and Martin Caceres did well to make clean contact with his weaker right foot, sending a volley just wide of the target.
The second half continued in the same vein as the first, with both teams lacking creativity in the final third.
