Meanwhile, the effect of Koshien Stadium on Furuya has become apparent, making him more focused on being the ace. What is it he sees, looking forward?

Sawamura is the starting pitcher in the practice game against Chiba's powerhouse, Naruta Industrial. How will his pitches fare against their batters known as the Southpaw Killers? It will be another trial for Sawamura, who must handle another big game. Plus, Naruta Industrial and Kuramochi have a previous relationship. What happened between then?

In order to prepare for unforseen circumstances in the summer tournament, Coach Kataoka has the players play out of their normal positions. Sawamura played left field in a practice game and Furuya played the infield during batting practice. Coach Kataoka asks straight-out if Yui, a first-year who made the first string, if he can play multiple positions. How will Yui, who has played catcher his whole career, respond?
