[CONCACAF UNDER-20 CHAMPIONSHIP] Mexico drew a crowd of more than 34,000 fans at the Estadio Cuauhtemoc in Puebla for its opening game at the Concacaf Under-20 Championship, but it quickly learned they're a tough bunch. Starting a pair of Americans, Richard Sanchez and Uvaldo Luna, Mexico jumped out to a 3-0 lead over Curacao but left the field to whistles from the crowd when the game ended with the same score.

Jesus Corona, who played for Monterrey in the 2010 Club World Cup, scored two goals and Pachuca's Marco Bueno had a goal and an assist as Mexico scored all three goals in the first 36 minutes.

Corona, Bueno and Sanchez, a backup keeper at FC Dallas, were among five starters who played on Mexico's 2011 Under-17 World Cup championship team.

Luna, who grew up in the Houston area and now plays for Tigres' youth team, assisted on Corona's second goal. The right winger previously played on the U.S. under-18 national team.

In Tuesday's other game, Jamaica beat Puerto Rico, 4-1. The University of Hartford forward Damian Lowe, the son of former national player Onandi Lowe, had the second goal for Jamaica. Sean Mcfarlane, who attended American Heritage School in Florida and plays for Division II St. Leo University, also started for Jamaica. American Reid Strain (University of Indianapolis) had the lone Puerto Rico goal.
