Nadia Podoroska is an argie junior player, she was born in Rosario, Argentina. Her surname comes from Belarus I think. Remember that Argentina is a country made of inmigrants from all over the world, so it's not weird having surnames from Russia and many others.
She's one of our best hopes for the future, plays really amazing and we all are enthusiastic about her.
She and her team are planning not to play juniors tour and getting directly to pro's. That's why she is, from those who were born in 1997 or later, the one with highest WTA ranking
Here you have some videos of her playing national pro tournaments:
