Youth-team defender Danny Potts has made his debut for the United States U20 side.
Potts, a left-back, played for the final 20 minutes as a substitute in the Americans' 2-1 friendly defeat by France in Vichy. The 17-year-old qualifies to play for the US through his father, Hammers great Steve, who was born in Hartford, Connecticut.
All three goals had been scored before Potts replaced Hertha Berlin player Terrence Boyd. Earlier, Derby County forward Conor Doyle had equalised Arsenal striker Gilles Sunu's opener before Olympique Lyonnais striker Yannick Tafer netted the winner eleven minutes after half-time.
The friendly international was the second between the two countries, with the first match ending in a 3-3 draw. Potts was not involved in that fixture, while West Ham club-mate Sebastian Lletget was excused the trip to allow him to return to his native California.
Having missed out on a place at the FIFA U20 World Cup this summer, Tab Ramos's squad are now preparing for the 2012 Olympic Games in London.
