Junior Kremlin Cup, Moscow, Russia, TEJT 14&U C1
R2: (1)Sofya Zhuk (RUS) df. Aleksandra Kasatkina (RUS) 6-4 6-2
R3: (1)Sofya Zhuk (RUS) df. (Q)Aleksandra Kulik (RUS) 6-3 6-0
QF: Anastasia Potapova (RUS) df. (1)Sofya Zhuk (RUS) 3-6 6-3 6-3
Meh. Potapova is extremely good though, I think she's the best 12&U in the world or something? And has a 40-1 W/L record in 2013.
But still she's a year younger than Sofya.
