Argentina captain Lionel Messi helped guide his nation to a second consecutive Copa America final after seeing off USA 4-0 on Tuesday night.
USA were without three first-team regulars as Jermaine Jones, Bobby Wood and Alejandro Bedoya were suspended for the match.
The South Americans went into the game with one forced change, the suspended Nicolas Gaitan being replaced by Ezequiel Lavezzi in the starting XI.
Argentina got off to a flyer when former Paris Saint-Germain forward Lavezzi opened the scoring in the third minute.
It didn't take long for Messi to get in on the action, his 32nd minute free-kick sailing into the back of Brad Guzan's net to give the Albiceleste a 2-0 lead at half-time.
Argentina began the second half as they finished the first, and in the 50th minute, Gonzalo Higuain tucked home his first goal of the game after his initial shot rebounded off Guzan.
The rout was completed in the 86th minute, when Higuain beat the USA goalkeeper again, this time thanks to a Messi assist.
