The Pacific League announced today that Senichi Hoshino will manage at the upcoming All-Star series. Former Rakuten interim manager Yoshinori Sato was slated to step in, but plans changed when he was replaced by Hiromoto Okubo on Wednesday.
There was a case in the past where the manager from the team that placed second the previous season stepped in to manage the series, but none that involved the third place manager. The PL did not want to set a new precedent and was more comfortable with the idea of working with the Rakuten Eagles. When the Eagles named Sato their interim manager, the league agreed to let him to take on the reigns with Hoshino acting as a "general" manager. But the decision was put on hold when Sato was replaced by Okubo on Wednesday. The PL discussed options and decided to ask Hoshino to manage the series.
FYI: The PL most likely did not consider Okubo an option because of his status as an interim manager replacing another interim manager. Okubo also told reporters on Wednesday that he did not want to manage the All-Star series and would turn the position down if asked.
[UPDATE 7/4 @ 2:42am]
The Eagles reportedly received a strong request from the Pacific League for Hoshino to participate. Both the organization and Hoshino agreed.
