You mean Miyashita? Sato is still unable to do anything strenuous similar to Shinnabe. I don't think Rivale even has a physiotherapist. Ageo for example just hired someone from Yakult Swallows after Yoshino got injured.
I do trust Haruka, she's doing fine but still didn't get called, and Nakada seems to love Sato more, so I'm not putting her above Sato
I'm assuming they're getting different kind of training? If the Momii-Seki-Tashiro messed up, they back to train for VNL
