Hikaru says he wants to be a pitcher because "it looks fun". Despite his terrible grip and form, his brutally fast balls are something to be reckoned with! After appointing Daigo his training partner, Hikaru casually suggests that the two of them form a battery.
Daigo refuses the idea as impossible, based on his arm being weak. However, his sister Izumi points out that his personality and knowledge of baseball would actually make him a good catcher.
You don't honestly think I could 
do it with my weak arm, do you?
أنت لا تظنين أنّي قادر على ذلك بذراعي الضعيفة، صحيح؟
Du denkst sicher, dass ich das
mit meinem schwachen Arm nicht kann.
¡No crees que pueda hacerlo
con mi brazo tan débil!
¡Sabes que con mi brazo
eso es imposible!
Pensi che ci riuscirei 
con un braccio di burro come il mio?
Você honestamente acha
impossível com meu braço fraco.
Я-то кэтчер, со своими слабыми руками?
