[OLYMPICS COUNTDOWN] Mexico tuned up for the Concacaf Under-23 Championship with a 2-1 win over Senegal thanks to two first-half penalty kicks by American-born Miguel Ponce in a friendly played Saturday at San Francisco's AT&T Park. Canada, which will face the USA in Group A, beat Trinidad & Tobago, 1-0, on Friday, thanks to a goal by Montreal Impact rookie Evan James. El Salvador, which will also meet in the USA in Nashville, Tenn., lost to Honduras, 2-0, on goal by Ever Alvarado and Eddie Hernandez in Houston.

The Mexico-Senegal game drew an announced crowd of 21,816 as part of a doubleheader with the San Jose-Houston MLS game.

Like the USA, Mexico has several national team regulars -- Giovani dos Santos, Jonathan dos Santos and Carlos Vela -- who will not be with the U-23s for qualifying.

Senegal is preparing for a playoff with the winner of the Asian playoff for a berth in the finals.

In the win over T&T, Canada coach Tony Fonseca said he was pleased with the play of a pair of MLS rookies, Bryce Alderson (Vancouver) and Babayele Sodade (Seattle).

Trinidad & Tobago has been training in Florida, where it beat the Honduras 5 Stars, 4-1, and lost to the NASL Fort Lauderdale Strikers, 4-1.

T&T will be without Khaleem Hyland, who was not released by his Belgian club Genk, and Mekeil Williams, who plays in Poland, was having trouble getting a visa to enter the United States.

The Houston-El Salvador game drew an estimated 23,000 fans at Robertson Stadium, the former home of the Houston Dynamo. Honduras was without Andy Najar, who will join the team in Los Angeles. He played Sunday for D.C. United in its 3-1 loss to the Galaxy.

Panama, which will compete in Group B with Honduras, Mexico and Trinidad & Tobago at the Home Depot Center, will leave for Los Angeles on Tuesday.

Coach Julio Cesar Dely Valdes has called in FC Dallas defender Carlos Rodriguez, one of seven foreign-based players.
