On the 20th, Softbank announced that it will send pitcher Ryotaro Sawayanagi to the Japan Winter League (the sending league is JWL Advance 2025) to be held in Okinawa in order to develop players.

Sawayanagi joined the team as the fifth pick in the 2023 draft and pitched in 11 games in his first season last year, but underwent Tommy John surgery in the same year and was relegated to the development team this season. He did not pitch in the minor league this season.
