A.J. DeLaGarza and Guam dropped the first match of their 2018 World Cup qualifying campaign on Thursday, falling to Asian power Iran 6-0 at Azadi Stadium in Tehran.

Iran jumped on the Matao almost immediately with a goal in the opening 10 minutes off a penalty kick from Ashkan Dejagah. The hosts went into halftime up by three goals as Mehdi Taremi and Sardar Azmoun scored before halftime. Taremi and Azmoun found the back of the net again in the second half before Mehdi Torabi rounded the scoring with a tally in the dying minutes of the match. DeLaGarza went 90 minutes in the defeat to Team Melli.

Despite the result, Guam remain atop Group D with six points while Iran are in second with four but holding a match in hand. DeLaGarza and Guam return to action on Monday when they host Oman at 11 p.m. PT.
