Mauricio Pochettino made 10 changes from the side that thrashed Peru 4-1 at the weekend, but the USA claimed another four-goal victory at Energizer Park, where Middlesbrough's Sebastian Berhalter played a starring role and was supported by some of the team's newcomers.
USA teenagers break records in friendly win
Teenagers Julian Hall and Mathis Albert were among the goalscorers as a new-look United States team beat Chile 4-2 in an entertaining friendly.
The St. Louis crowd was treated to an open start as Lawrence Vigouroux got down well to repel Miles Robinson's header, before Ben Brereton Diaz and Dario Osorio both struck the woodwork in the space of two minutes for Chile.
The USA went in front in the 37th minute as Hall cleverly dummied Sergino Dest's pass through to Berhalter, who applied a calm finish, though some weak goalkeeping from Chris Brady allowed Diego Ulloa to prod the equaliser over the line in first-half stoppage-time.
Chile then went in front through a rasping strike from Maximiliano Gutierrez four minutes into the second half, but the USA was only behind for a couple of minutes as Hall's glancing header diverted Gio Reyna's inswinging cross home.
The USA led again when Chris Richards powered Berhalter's corner past Vigouroux with 72 minutes gone, and scpred a clinching goal in stoppage-time.
Auston Trusty headed Antonee Robinson's free-kick back across goal, and on the stretch, Albert diverted the ball off the underside of the crossbar and in.
