MEXICO CITY, May 13 (Reuters) - Striker Francisco Fonseca scored two first-half goals for Mexico to beat Democratic Republic of Congo 2-1 in a friendly at the Azteca stadium in their last home game before the World Cup.

Fonseca, who took his tally to 19 goals in 28

internationals, opened the scoring in Friday night's game after

heading in a cross from strike partner Jose Antonio Castro in

the third minute.

Castro was a constant threat for Mexico down the right,

although the Simbas had a chance to equalise when Gladys

Bokese's left-foot shot was turned away by goalkeeper Oswaldo

Sanchez in the 19th minute.

Four minutes before halftime, Fonseca was on hand to score

again after another Castro cross was misjudged by goalkeeper

Pascal Kalemba.

The 75,000 crowd got ready for a flood of goals in the

second half but instead Claude LeRoy's team reduced the deficit

in the 50th minute when Dieu Mbokani broke down the right and

fired past Oswaldo Sanchez.

Mexico, who were without defender Rafael Marquez and

strikers Jared Borgetti and Guillermo Franco, face Iran, Angola

and Portugal in their group at the World Cup.
