Because I'm The Ace (エースだから, Esu Dakara) is the eleventh episode of season two.
At the bottom of the seventh, the Tajima-Mihashi battery gives up two runs. Bijou figures out that Momoe is calling out strikes or balls. After Mihashi easily acquiesces to Abe's order to listen to Tajima's calls, Abe starts to feel guilty about Mihashi's absolute obedience to him and resolves to apologize after the game. Mihashi feels guilty that Abe is the only one to strategize and has to look after him. The score in the eighth inning is 0-1.
