US U-20 national team head coach Tab Ramos named his squad for a training camp and two friendlies in Spain ahead of the U-20 World Cup this year.

Ten current MLS players from 10 different teams were included in the 20-player roster, with the camp and friendlies taking place in San Pedro del Pinatar, Spain. Among the call-ups are four MLS rookies: Seattle Sounders goalkeeper Trey Muse, Columbus Crew SC defender Aboubacar Keita, FC Cincinnati midfielder Frankie Amaya and New England Revolution forward Justin Rennicks.

They will play France on March 22 and Japan on March 25.

The US will play in the U-20 World Cup in Poland in May, where they are scheduled to play in Group D against Ukraine, Nigeria and Qatar.

“Im looking forward to our last camp before the U-20 World Cup,” Ramos said in a statement. “With competition against two quality opponents, it’s one more opportunity for us to build a strong core and one more chance for the players to leave a good impression in order to be considered for the final 21-player roster. Japan always has highly skilled youth teams and France is always a World Cup contender.”
