I just watched this video and felt nostalgic. Can't believe it was 5 years ago already. Both were among the most promising young players at that time. And now, one is retired (Ksyusha hasn't played a tennis match since Sept 2012) and one gave up on singles (Oksi is basically only playing dubs now).
I still have hope that somehow Ksyusha will attempt a comeback someday, and Oksi will give it another try in singles. But I'm not too optimistic, that's more wishful thinking.
Really hope she'll consider playing tennis again, and that we'll somehow see her on a tennis court playing competitive tennis again someday soon. She's only 24 after all, and has way too much talent to leave it like that.
