▼ Comment from pitcher Ryodai Miura

"Today, by signing the contract, the feeling of becoming a professional baseball player has become even more real. Since the season starts earlier than before, I will focus on physical conditioning during the off-season while being careful not to over-pitch. I want to prepare thoroughly so that I can make an impact starting from the rookie joint independent training in January. My goal is to earn a spot on the active roster in my first year and succeed at the major league level. I will do my best to become a pitcher who represents Japan in the future."
