As to why I’ve said that Hanai is a winner is because in this episode, he conquered his insecurities against Tajima. Thanks to Momokan and the rest of the team especially Tajima and Mihashi. He also says that without an internal competition within, a team would be no good. He also found out that Mihashi always thinks that Tajima and Hanai would compete with him in terms of being in the mound and pitching.
Nothing more has been given concentration here. But towards the end, the guy (fourth to the last panel) stated that he has found a strategy to defeat Nishiura, that is to beat the catcher, Abe Takaya. (I did post about this during the episode 1 review)
