Senichi Hoshino passed away earlier this year in January. The Rakuten Eagles announced on March 26 that they decided to honor him by retiring the uniform number (77) he wore while he managed the team. The number will also be added to all team uniforms (left chest area) for the duration of the 2018 season. For the home opener, the number will appear on the mound.
Hoshino’s number 77 joins the number 10 as the only two numbers to be retired by the Eagles (the number 10 was set aside for the fans). The Eagles are the first team in NPB history to retire a manager’s number.
