Figured for this episode I'd give a rundown, more than a review.
This is a one off episode that revolves around Haruna, the pitcher team Nishiura goes to watch in episode 9. Haruna is Abe's old battery mate and all Abe can talk about is how he's selfish and only plays for himself. In this episode we witness a day in Haruna's freshman year where he shows his work ethic and also his desire to see his teammates also do well in baseball.
It's a strange episode, as it's completely random to the story line, but shows that they could have had a decent spin off if needed.
