At the post-Denmark mixed zone, I was giving Jonny Bornstein a bit of a hard time, saying, "Well, I guess this is it for playing with Mexico's team." A USSF employee who was escorting Bornstein from the press conference interjected.
"No - he's not cap-tied until he plays in an official competition or qualifying."
Bornstein himself nodded in agreement. "Friendlies don't captie you."
He quickly added that he wanted to play for the U.S., though.
I have no idea whether this pertains to Freddy Adu, at all, as he only played a few minutes in a friendly against Canada, but apparently Bornstein could play against and even score against Mexico on Feb. 7th, but still be eligible to play for them.
Anyway, I guess Gold Cup is the soonest he could be captied to the US.
