Colorado Rapids Homegrown player Dillon Serna has been added to head coach Tab Ramos’ 20-player roster for the CONCACAF U-20 Championship, beginning Feb. 18 in Puebla, Mexico.

The Brighton, Colo., native was signed by the Rapids after being part of the club's U-15/16 and U-17/18 US Soccer Development Academy teams. Serna played in three matches with the U-20 MNT in 2012.

Ramos announced an initial 18-player roster on Feb. 7 and the team named forward Jerome Kiesewetter to the roster on Feb. 11. The team is training in Toluca, Mexico, but will travel to Puebla this week.

The US U-20 MNT is looking to qualify for the 2013 FIFA U-20 World Cup in Turkey from June 21-July 13.

The U-20s open the CONCACAF U-20 Championship group stage against Haiti on Feb. 18 and Costa Rica on Feb. 22 at Estadio Olímpico Universitario Lobos BUAP in Puebla, Mexico. Both Group A matches kick off at 5:30 p.m. CT and are televised on FOX Soccer.

The top four teams from the CONCACAF U-20 Championship advance to the U-20 World Cup.
