1 - 51: The Battle Begins!

Seidou battles Inashiro for the right to go to Nationals. Mei overthinks his opening battle with Kuromichi and walks him. Kuromichi steals second base standing up, a sacrifice bunt from Kominato moves him to third, and a base hit from Isashiki gives Seido a 1-0 lead. Seeing nothing to lose, Mei decides to battle Yuuki one-on-one as the rest of Seidou watches wondering if Mei is losing it.
