Brandon Vazquez put the U.S. in front at the half-hour mark with a glorious header, but the Americans fell apart at two key moments.A free kick just before halftime from Luka Ilic broke a weak U.S. wall and leveled the score. Veljko Simic punished an ugly mistake at the back seconds after the second-half restart.The U.S. was in charge for most of the second half but couldn't find an equalizer despite the presence of veterans Kellyn Acosta and Paul Arriola off the bench.Cade Cowell was sensational, standing out above the rest of the squad in his 72 minutes. The 19-year-old winger combined well with Jonathan Gomez on the left flank. Alejandro Zendejas was bright toward the end when moved centrally.Defeat is difficult to swallow in the first friendly back after the World Cup, but results are le s important than the performance, and there are positives to take from these 90 minutes.

He was by far the best player on the field for either team, continually cropping up down the left to cause problems, either by cutting inside (which he clearly favors) or by occasionally springing down the flank to send in a cro s.Cowell was extremely unlucky to not have picked out a goal, . He combined extremely well with Jonathan Gomez on the left; the fullback did well to overlap on several occasions, which allowed Cowell to drift centrally both on and off the ball.The 19-year-old surely has earned himself more minutes, either against Colombia or beyond, with the national team.Round of applause for Cade Cowell, who was sensational for the . Nobody else really covered themselves in quite the same amount of glory. A fabulous 73 minutes. Kyle Bonn (@the_bonnfire) Multiple dual nationals stood out for the USMNTSeveral players who have chosen the United States (for now) were exceptional.Gaga Slonina, who has chosen the United States over Poland, was very good in goal, especially with his two big saves in the first half. He could have done better to set the wall on Serbia's equalizer just before the break, but he'll also know his defenders ultimately parted to allow the shot on frame.Alejandro Zendejas, who has been heavily courted by Mexico, was exceptional Reggie Jackson Jersey , building in influence as the game went on, especially after he moved more centrally in the final 30 minutes. Jonathan Gomez was solid at left back, and although he showed some defensive vulnerabilities, his attacking combo with Cowell was great.Goal scorer Brandon Vazquez was also eligible to play for Mexico in the past, but he has finally earned his first U.S. cap.All in all, it was a great night for dual nationals wearing the U.S. Soccer crest.4 highly touted Mexican-American dual nationals started for the USMNT tonight (+ a goal). Have a good night FMF Michele Giannone (@MicheleG3) Mistakes will be punished at this levelThe U.S. was playing against an extremely inexperienced and fringe Serbia team, but the punishment for mistakes was all the same.Jalen Neal and Jonathan Gomez were caught with their pants down on the second Serbia goal. It's a tough pill to swallow knowing the U.S. probably should have put away more chances up front but were punished in such a way at the back.Those kinds of brain farts will not fly in any Glenn Hubbard Jersey senior international match. It's a valuable le son for the youngsters and debutants in the U.S. side, one that acting head coach Anthony Hudson will be sure to point out as they switch gears toward the Colombia friendly on Saturday.After beating the USMNT in LA, Serbia coach Dragan Stojkovic ended his excellent news conference with: Thank you. I am going to Miami tomorrow. Greg Beacham (@gregbeacham) FULL TIME: USA 1-2 SerbiaIt's defeat for Anthony Hudson and a young U.S. side, as the mistakes bracketing halftime were too much to overcome. The United States was on top for most of the second half but failed to get past a stout Serbia back line that repelled every attacking move, especially the gluttony of cro ses the U.S. sent into the penalty area.Cade Cowell's performance was the standout takeaway from this Rollie Fingers Jersey match, and a few other players did well with their roles. It was a tough night for Jalen Neal at the back, but overall there are plenty of positives to take away from this game, and the experience will be valuable for those players on the field.USA vs Serbia: Second half88th min:Aidan Morris earns what is a very soft yellow card for giving chase in midfield for a 50/50 ball. Then it's Marko Mijailovic who goes into the book for hacking Jonathan Gomez down on the break. That's how you get your money's worth.Kellyn Acosta's free-kick delivery is poor as regulation time expires and five minutes of added time is ahead. He was looking for Aaron Long at the far post but it's too deep.85th min:Nemanja Petrovic picked up the first yellow card of the match for a foul in midfield. Moments later, the U.S. has a penalty shout as Kellyn Acosta springs Alejandro Zendejas, and Petrovic challenges hard, but the referee waves away the protests. It's the right decision, as there wasn't enough in that battle for the ball.
