9th Inning (9 回, 9 Kaisen) is the twelfth episode of season two.
Mihashi goes past his 100th pitch. Momoe realises Bijou has decoded Nishiura's signs. Momoe tells Tajima to decide pitches with Mihashi. After a three-run homer, Mihashi is badly shaken up and ends up giving up a walk to the next batter, unable to locate his pitches. Mihashi sees the importance of a pitcher's decision to follow the catcher's signs. Mihashi manages to strike-out the next batter, Kurata, the catcher, in that mindset. Bijou's Kashima is replaced by Takenouchi as pitcher. Moriya replaces Takenouchi in left field. Nishihiro, the reserve player, gets the last at-bat with two outs, but strikes out and the game ends with the ninth inning (4-1). Nishiura loses 11-6. Although they've lost, Momoe tells them to look forward to the Newcomers Tournament and the Fall Tournament.
