Chicago, Jun 13 : Andres Guardado scored twice and Rafael Marquez and Pablo Barrera each added a goal as Mexico cruised into the quarterfinals of the Gold Cup with a 4-1 victory over Costa Rica.
The defending champions easily won Group A despite its squad being reduced to 17 players after five were suspended last week for testing positive for clenbuterol.
Mexico's 14 goals are the most of any team in the tournament. El Tri has also conceded just one, a 69th-minute strike by Marco Urena of Costa Rica.
Mexico now faces the third-place team from Group B or Group C in Saturday's quarterfinal match.
Costa Rica also advanced after finishing second in the group, ahead of El Salvador on goal differential. AP
