[HEXAGONAL] Javier Aguirre begins his second stint as Mexico's national team coach when the Tri visits El Salvador's Cuscatlan Stadium on Saturday (TV: Telemundo, live, 9 pm ET). Eight years ago, he turned the Tri's foundering World Cup 2002 campaign around and led it to the finals. In its first three games of the 2009 Hexagonal, Mexico lost two of its three games, so it needs at least a point in San Salvador to reverse course.

Aguirre brought the Chicago Fire's Cuauhtemoc Blanco out of international retirement at the age of 36, though it's how those players who have been with the team for this year's Hexagonal take to Aguirre that will be critical.

"Javier's arrival has motivated us," said striker Nery Castillo. "It has made us change our way of thinking and I think we're going to be in the right frame of mind for Saturday's game."

Trinidad & Tobago also has changed coaches since the last pair of Hexagonal games and will look to get out of last place when it hosts new leader Costa Rica.

Longtime national team player Russell Latapy, who was on the bench as an assistant coach and eligible player for T&T's 3-0 loss to the USA in Nashville, replaced Colombian Francisco Maturana.

Latapy has brought in a pair of MLS players, D.C. United's Avery John and new San Jose signing Cornell Glen, for Saturday's game.
