Relatives of Clark were in Port of Spain's Hasely Crawford Stadium.
"It feels good," said the Houston Dynamo midfielder. "They were at the game watching me play. It was something special to have a good showing in front of somebody who
has been a part of your life for so long. I have family here and my dad was born here. It was a special game for me and I thank god I was able to take advantage of the opportunity."
Clark, who didn't dress for the USA's 2-1 win over El Salvador last Saturday, was on the verge of being substituted when his blast hit the T&T net.
The 26-year-old was born Atlanta and played two years of college ball at Furman before joining MLS. After two seasons with the MetroStars, he played for San Jose one season before the team moved to Houston, where Clark won two MLS titles.
