Tyler Adams picked a good time to open his United States national team account.
The 19-year-old New York Red Bulls midfielder scored his first senior international goal in the second half to give the USMNT a 1-0 victory over Mexico.
Moments before, El Tri had been reduced to 10 men after Angel Zaldivar was sent off for a dangerous tackle on Wil Trapp.
Mexico had generated more of the threatening chances prior to that point, but following the red card, the USMNT gained a foothold into the game.
Four minutes after the card, second-half substitute Antonee Robinson delivered a low cross into the area that evaded multiple Mexico defenders.
