The USA was without Mark McKenzie, who will join the team in Bradenton after playing for the Philadelphia Union in its 3-1
loss to New York City FC in the MLS playoffs on Wednesday night. David Ochoa, who spent the 2017-18 season in the Real Salt Lake academy, replaced CJ dos Santos, who remained at Benfica,
where he is in its youth program.
In other Group A openers, Suriname beat the U.S. Virgin Islands, 13-2, and Trinidad & Tobago edged St. Vincent & the Grenadines, 3-2. The USA's next game is against the U.S. Virgin Islands on Saturday.
Only the six group winners advance to the semifinal group stage in the marathon U-20 tournament. The top two teams from the two three-team groups will advance to the 2019 Under-20 World Cup in Poland.
Notable: FC Dallas rookie Brandon Servania started in midfield for the USA, lining up against his brother, Jaden Servania, who started for Puerto Rico. The Servanias hail from Alabama. Brandon turned pro in 2018 after one season at Wake Forest. Jaden Servania, a high school senior, switched to the Houston Dynamo's academy program from FC Dallas' program.
