When I was reading more about Collarini, I came across this paragraph...
It happened this year in the case of Sean Berman, who reached January’s Australian Open boys’ final. The USTA, which funded Berman for several years, declined to offer his immediate release when the South Africa-born Berman declared his intention to play for Australia. “We would not release him because we had given him direct financial support,” Curry (USTA spokesperson) said.
How did this ever end with Berman, who was not American born, did the USTA recoup their money?
