SAN JOSE, Calif. – San Jose Earthquakes midfielder Tommy Thompson was among 20 players called to the U.S. Under-20 Men’s National Team by head coach Tab Ramos for the U-20’s second foreign training camp of the year to be held from April 18-26 in Linz, Austria.

Thompson, 19, was previously called to the team’s first foreign training camp of the year in England from March 23-30. He also played a critical role in the success of the U-20 national team in its qualifying for the 2015 FIFA U-20 World Cup in New Zealand, helping lead the U.S. to a 4-1-1 record at the CONCACAF Championship in Jamaica. Thompson started all six games for the United States in the tournament and recorded a goal in an 8-0 win against Aruba on Jan. 14.

During camp, the U-20 MNT will play friendly matches against fellow U-20 World Cup side Qatar on April 21, followed by a matchup against Croatia on April 25. Both games will be played at Red Bull Arena, home of FC Red Bull Slazburg in Wals-Siezenheim, Austria.

This will be the second camp of the year for Ramos’ group, who recently returned from a seven-day camp in England where it faced England’s U-21’s on March 29. This Austria camp will continue the USA’s preparation for the 2015 FIFA U-20 World Cup, which takes place in New Zealand from May 30-June 20.

Eleven of the 20 players on the roster were part of the U.S. team that competed in the 2015 CONCACAF U-20 Championship and qualified the USA for the U-20 World Cup, while 12 players from the March camp in England return to be part of this squad.

All 20 players in the group have been previously called up to a camp or competed with the U-20 MNT since the 2014 cycle began.

Only three players will be joining the U-20’s for the first time in 2015: midfielders Jordan Allen and Christian Roldan and forward Zach Pfeffer. Pfeffer has seen time with the U-23’s this year, and was called up to join the team during its training camp in Copenhagen on March 30.

Nine players represent clubs in Major League Soccer: defenders Conor Donovan (Orlando City SC), Matthew Miazga (New York Red Bulls) and Erik Palmer-Brown (Sporting Kansas City); midfielders Allen (Real Salt Lake), Marco Delgado (Toronto FC), Romain Gall (Columbus Crew SC) and Roldan (Seattle Sounders FC); and forwards Pfeffer (Philadephia Union) and Tommy Thompson (San Jose Earthquakes).

The USA was drawn into Group A of the U-20 World Cup alongside host New Zealand, Ukraine and first-time participant Myanmar. The U.S. opens the tournament May 30 against Myanmar, continues play on June 2 against New Zealand, and wraps up the group stage against Ukraine on June 5.
