Argentina struggles into Copa quarters

Argentina marked Lionel Messi's 100th cap with an unconvincing 1-0 win over Jamaica to reach the Copa America quarterfinals as group winner on Saturday as holder Uruguay also advanced to the last eight.

Napoli striker Gonzalo Higuain rifled home the only goal for Argentina as the tournament favorite downed the Reggae Boyz in Vina del Mar to clinch top spot in Group B ahead of Paraguay and Uruguay.

But it was another patchy performance from the 2014 World Cup quarterfinalist, who struggled to break down a team ranked 62 places below it in the latest FIFA standings.
