I Don't Want to Lose
Mei battles Yuuki one-one-one. Then it's time for Furuya to shine. Furuya throws his own team for a loop when he thanks them for helping him be successful. He then proceeds to strike out the side. Miyuki and Mei go head-to-head, and Mei gives Miyuki exactly what he wants in a change-up, but with no one on it turns into an easy out. Furuya comes out for the second and strikes out the clean-up and #6 batters, though Mei manages to pop out to third instead of striking out. With Furuya throwing with more control and speed than ever, Inashiro realizes they will have to change something up to be successful. It's the end of two, and Seidou leads 1-0.

However, now surrounded by a large number of skilled players, Eijun struggles to find his place on the team.
