Michael Halliday, Alex Freeman and Thomas Williams called up to US U20 National Team

Orlando City homegrown defender Michael Halliday, Alex Freeman and Thomas Williams were called up to the United States U20 National Team Friday. The trio all have prior youth national team experience.

Halliday is the most experienced international of the group. The 19-year-old right back has six appearances with the U20 national team, and he could be a key starter for the US at the U20 World Cup this summer. Halliday is also the closest to breaking through with Orlando City's first team with 15 appearances for the senior Lions.

Freeman previously played with the US U19 team, and this is his first opportunity with the U20's. The attacking right back signed his homegrown contract last season and played 19 times in MLS NEXT Pro. The 18-year-old defender had three assists last season with Orlando City B. This is Freeman's first appearance with the U20 team.

Williams made his first five appearances with the Orlando City first team this past season. The 18-year-old center back made three appearances with the U17 national team and played four times with the U19's. He earned a call-up to the U20 national team before, but has yet to register an appearance.

The players will participate in a January training camp as the U20 team prepares for the World Cup in May. The camp runs from Jan. 19 to Jan. 29. The 23-man roster is almost entirely comprised of domestic based players with just three players at European clubs.

Orlando and the Philadelphia Union are the only teams with three players on the roster. Atlanta United and the San Jose Earthquakes are the only other teams with at least two players participating in the camp.

Former New York Red Bulls attacker Caden Clark and Union midfielder Jack McGlynn headline the squad. Among the other intriguing names to follow are San Jose midfielder Niko Tsakiris, Philadelphia attacker Quinn Sullivan and Real Salt lake midfielder Diego Luna.
