Hate to say it but this kid and his family seem like mercenaries content to jump nationalities whenever better funding opportunities pop up.
Was born in South Africa
Grew up in New Zealand
Spent years 13-17 living in California and playing for US
Now playing for Australia
Makes the Kazakh team look like the most patriotic guys ever by comparison.
Anyway, I watched him play in Kalamazoo last year and he didn't stand out at all. If you'd have told me he would be in the final of the AO Juniors the next year I'd tell you that you were crazy. AO juniors field is a bit weaker than the other junior slams but all the same I am surprised to see him having such success.
With all this said I think his efforts at the pro level so far have been pretty solid and I wish him the best of luck.
