Erik John Ustruck (born January 4, 1985 in St. Louis, Missouri) is an American-born Guamanian international footballer who played for Orlando City in the USL Professional Division, and now is a youth coach for Orlando City's youth development program.
Ustruck played four years at Santa Clara University, scoring eight goals during his collegiate career and fighting back from a knee injury during his junior year. He was noted for his versatility and work ethic.
Ustruck was drafted by the Dynamo in the third round of the 2007 MLS Supplemental Draft – a draft that he watched online with his friends – as the 39th supplemental pick overall. Though he played as both a forward and a midfielder in college, Ustruck appears likely to be converted to a right back or right-sided midfielder in MLS.
He played several games with the Under-20 United States national team in 2004, but never made an official FIFA or confederation appearance for the senior team, so he is not cap tied to any National federation. He was also selected into the Guam National team preliminary squad for the AFC Challenge Cup qualifiers in February 2013. He made his debut for the Matao against Laos in November 2013 during the FIFA International friendly between the two nations.
