Really sad for Melnikova. I dont know whether Mustafina at the moment just cant do better than 58.0 or if she just had a bad day. There are quite a lot of girls who can score 58.0 and fight for bronze, 1 or 2 british girls, Steingruber, 1 or 2 chinese girls and maybe even Saraiva or one of the japanese girls. Her score on uneven bars was amazing, i doubt that anyone will be able to beat that. Paseka also should be safe to make the vault final, but if the girl from north korea keeps her level, then Paseka wont have a chance for gold. The russian girls might leave Rio with only 2 or 3 medals.
I think Alt might also challenge for the final on balance beam if she can keep her nerves, recently she has been on pretty much the same level as Schäfer and she has the same difficulty, although Schäfer scored 15.1 once. So far scores on balance beam have been pretty bad, this might be a big chance for the 2 german girls.
