[UNDER-17 CONCACAF CHAMPIONSHIP] Mexico, winner of the Under-17 World Cup in 2005 but unable to qualify for the final two years later, very much means business at the 2009 Concacaf U-17 Championship, opening with a 7-0 over Trinidad & Tobago before 13,333 fans.

Mexico led 3-0 within a half an hour on goals by Carlos Campos, Martin Galvan and Victor Manon.

In the second half, Galvan scored twice more goals to finish with a hat trick, and Luis Telles and Salvador Jasso also scored.

Mexico will qualify for the 2009 Under-17 World Cup in Nigeria with a win over Guatemala on Friday.

Qualification would end a skid for Mexico, which also failed to qualify for the 2008 Olympics (under-23) and 2009 Under-20 World Cup.

Costa Rica and Guatemala played to a 1-1 tie in the other Group B game.
