The teams came into the match on the back of polar opposite results - Costa Rica despatching Cuba 5-0 and El Salvador hammered by the same margin by Mexico.

But that meant little when Rodolfo Zelaya put El Salvador in front on the stroke of half-time with a fine free-kick.

Brenes entered the fray in the 80th minute and there were only seconds left from six extra minutes when he fired low past Miguel Montes.

In the day's second match, Mexico brushed aside the news that five of their players had been suspended following failed drugs tests to defeat Cuba 5-0.

It was the Mexicans' second five-goal success in as many games, as well as Cuba's second five-goal reverse.

Manchester United striker Javier Hernandez followed up his opening day hat-trick against El Salvador with two more goals, in the 36th and 76th minutes.

Giovani Dos Santos weighed in with two of his own in the space of five second-half minutes and substitute Aldo de Negris also found the net.
