USA celebrated the centenary of their football federation with a thrilling 4-3 victory over Germany at the RFK Stadium on Sunday.
Juergen Klinsmann, who earned 108 caps and scored 47 times as a player for Germany, saw his USA side go 2-0 up inside 16 minutes before the visitors pulled one back in the second half.
However, a brilliant brace from Clint Dempsey proved to be enough for the hosts to claim their first win over Germany since 1999, despite late goals from Max Kruse and Julian Draxler.
Klinsmann made four changes to his side beaten 4-2 by Belgium on Thursday, with Brad Evans coming into the starting line-up at right-back.
Joachim Loew had a number of Bayern Munich and Borussia Dortmund regulars missing due to their involvement in the UEFA Champions League final, but Lazio striker Miroslav Klose started up front.
The hosts began the game brightly and Jozy Altidore had an early chance to test Germany, as he latched onto a long ball inside the area, but Per Mertesacker managed to make a strong block.
The Arsenal centre-back had a great chance to score himself, after beating DaMarcus Beasley inside the area, but he managed to bundle his shot wide of the post from close range.
Altidore continued to make a nuisance of himself and eventually put the USA ahead in the 13th minute with a stunning first-time volley from a pinpoint Graham Zusi cross.
Things went from bad to worse for Germany a few minutes later as goalkeeper Marc-Andre ter Stegen scored a calamitous own goal to make it 2-0.
The 21-year-old failed to control an innocuous back pass from Benedikt Howede and the ball went under his foot and rolled into an empty net.
The USA continued to threaten the German goal throughout the opening exchanges and captain Dempsey forced a strong save from Ter Stegen with a fierce half-volley.
Germany did have the ball in the back of Tim Howard's net in the 23rd minute, but Klose was flagged offside after he latched onto a through ball.
Loew's side started to impose themselves and create more chances during the final ten minutes of the opening period, and they managed to half the deficit six minutes after the restart.
Kruse won and crossed a corner into the six-yard box for fellow substitute Heiko Westermann to plant a powerful header past Howard.
However, just as it seemed Germany would push for an equaliser, the USA regained their two-goal cushion through Dempsey.
The Tottenham Hotspur midfielder fired home a perfect half-volley after some great work and a cross by Altidore on the left side of the German box.
Dempsey put the USA further ahead four minutes later as he danced past Lukas Podolski on the edge of the area and curled a sensational left-footed shot into the top corner.
However, the hosts allowed Germany back into the game as they conceded two quick-fire goals to ensure a nervy finish.
Kruse rifled a fantastic driven shot past Howard for his first international goal, before the Everton goalkeeper parried a Sidney Sam shot straight to Draxler, who tucked the ball away to make it 4-3 in the 81st minute.
There was a flurry of chances during the closing stages and the visitors had a half-hearted penalty appeal turned down, but the USA held on to claim a morale-boosting victory.
