The US U-23 national team kicked off play in the United International Football Festival in the Canary Islands on Thursday, falling 1-0 to their Brazil counterparts in the first of two games the Americans will play in the friendly tournament.
All told, 13 current MLS pros featured in the match for the US.
Thursday's loss means the US will play for third place in the tournament, against the losing side in Thursday's clash between Chile and Argentina.
The tournament is intended to be a warm-up for the USMNT ahead of Concacaf 2020 Olympics qualifying, which will take place in Guadalajara, Mexico, in March and April, when Jason Kreis' squad will attempt to return to an Olympic tournament for the first time since 2008.
USMNT U-23 lineup vs. Brazil U-23: GK - Matt Freese; Aaron Herrera, Justen Glad, Mark McKenzie, Sam Vines, Jonathan Lewis (Mason Toye 46'), Djordje Mihailovic (Emmanuel Sabbi 85'), Jeremy Ebobisse (Christian Cappis 46'), Richie Ledezma (Bofo Saucedo 46'), Brooks Lennon (Alex Mendez 77'), Hassani Dotson (Brenden Aaronson 46')
