Not a team event, so technically not representing anyone but oneself. The country beside the name is merely the country listed in the bio. Doesn't have to be one's only country of citizenship - just the one the player chooses to list. (Olympics are a different animal, since you have to be nominated by your national federation - similar to Davis Cup - and technically even individual athletes are playing for country there. Anywhere else, player plays for himself.)How did he not technically play for the USA? He played a round of qualifying and USA was next to his name, so he played under the American flag. Seems there are different restrictions for team events, but it is odd to me to be able to represent one country as an individual in an ITF event and one country in a team ITF event :shrug:
Pretty sure he has never represented a national team in recognized international competition.
