Hobro midfielder Christian Cappis and Llanez, who is in his first season at Wolfsburg's U-19s, are the two European-based players picked, joining 22 MLS players on the 25-player squad. Kayo is the 25th player.
Fourteen players are age-eligible for participation in the 2020
Concacaf Olympic qualifying in March, and 12 are uncapped. Llanez, Araujo and Kayo are also eligible for the 2021 U-20 World Cup for which the USA will take part in qualifying this summer.
The squad includes Bill Hamid, who was called up for the first time since Berhalter took over as national team coach a year ago.
The only starters from the 4-1 win over Canada in the Concacaf Nations League last month called up were Aaron Long, Jackson Yueill, Sebastian Lletget, Paul Arriola, Gyasi Zardes and Jordan Morris. Walker Zimmerman, Cristian Roldan, Long, Arriola and Zardes are the only starters from the all-MLS team that beat Costa Rica to end Berhalter's first January camp at the beginning of the year.
“At the start of an exciting year, this is a great opportunity to continue our process and build on the foundation established in the last 12 months,” Berhalter said. “At the same, there are a number of players getting their first exposure to the senior national team who will be provided the platform to make a positive impression. We appreciate all the support and cooperation from MLS and the clubs that released their players and gave us a chance to get a head start on the challenges ahead.”
Since the camp is outside a FIFA window,
clubs -- including MLS clubs -- aren't required to release players. Five MLS teams are allowed to open preseason camp early because of their participation in the 2020 Concacaf Champions League.
