On the 29th, the Rakuten Eagles announced that they have notified catcher Toshiya Osakae (19) that they will not be renewing his contract for the upcoming season. It is expected that the club will offer him a developmental contract in the future. He visited the club office in Sendai City and accepted the decision, stating, 'I think I was prepared for this, so to be honest, I am surprised, but since it is the club's decision, I don't have any particular feelings about it.'

Daiei is a catcher who joined the team from Gakuho Ishikawa as a fourth-round draft pick in 2025. In his rookie year this season, he had no first-team appearances, and in the farm league, he played in 24 games with a .182 batting average, 1 Home Run, and 7 RBI. He expressed his determination, saying, 'There are still areas where I haven't been able to fully demonstrate my strengths. I want to prepare thoroughly so that I can start next year in good condition.'

With both achievements and challenges in mind, he is envisioning a breakthrough for next season. 'First, I want to be able to play with confidence. I hope to work hard so that I can be promoted to the main roster as soon as possible,' he vowed as he made a fresh start.
