In a tense and exciting encounter the South Americans made their scoring chances count. Matias Luciux hit home in the second minute with an opportunistic strike, and the scoreline remained 1-0 for the Argentines through to the half.
Nine minutes into the second period, Fernando Wilhelm added a second as Argentina looked well on their way to a victory over the Central Americans, who were - in fairness - the better team in the second half. Although Manuel Aristondo pulled one back for the Guatemalans in the fading moments, the end result saw Argentina cruise through 2-1.
Argentina finish second in Group C and move on to the knockout rounds alongside Ukraine, who won the section with a victory over China PR. Guatemala, despite picking up four points from their games, head out of the competition.
Argentina will meet Paraguay in an all-South American second-round showdown on Saturday.
