DALLAS - Costa Rica and Mexico cruised into the semi-finals of the CONCACAF Gold Cup after convincing victories on Sunday. Striker Alvaro Saborio scored twice to help Costa Rica thrash Guadeloupe 5-1 while Mexico's Miguel Sabah got two in his team's 4-0 win over Haiti. The pair will meet in the semi-final in Chicago on Thursday. The United States meet Honduras in the other semi-final. More than 80,000 were present to watch the first sports event at the new Dallas Cowboys stadium and the venue was given a fitting opening with a superb opening goal from Costa Rica. A stunning overhead kick from Celso Borges put the Costa Ricans ahead in the third minute - the striker producing an acrobatic finish to an Armando Alonso cross. The lively Alonso created Costa Rica's second when he crossed to Saborio who smartly headed home in the 16th minute. Costa Rica took firm control after the break with a goal from Andy Herron and although Guadeloupe pulled one back, thanks to Alexandre Alphonse, the outcome was never in doubt. Saborio grabbed his second after racing on to a fine through ball from Borges to make it 4-1 and then Pablo Herrera completed the rout a minute from the end. Sabah opened the scoring for Mexico, slotting home after Israel Castro's penalty was pushed out by Haiti goalkeeper Jean Zephirin. Giovanni Dos Santos then doubled the advantage with a magnificent strike from the edge of the area and after the break he turned provider, delivering the cross which Sabah headed home for his second and Mexico's third. An excellent Mexico display was rounded off when Dos Santos swung in a deep corner which substitute Pablo Barrera crisply volleyed home.
