楽天は１７日、新監督として前ロッテ監督の吉井理人氏（６１）が就任することを発表した。吉井氏と三木谷浩史オーナー（６１）らが宮城・仙台市内で会見。シーズン途中での異例の人事に踏み切った理由について、三木谷オーナーは「中長期的に球団の方向性、また様々な改革をしないと、継続的な強い球団は作れないと考えて」と説明した。

　同オーナーによると、面会して「ダメ元」で監督就任のオファーをしたところ、「火中の栗を拾う」という形で引き受けてもらったという。契約期間に関しては「中長期的な契約」と言及した。

Rakuten Eagles was in contention for first place until mid-April this season, but then their performance plummeted. After 63 games, they are struggling with a record of 23 wins, 39 losses, and 1 tie, putting them 16 games below .500. They even changed their coaching staff in May, but still saw no dramatic improvement.

At 1:00 AM on the 10th, after The Giants game in which the team's deficit reached 15 games (according to Rakuten Eagles Mobile), the team made a surprise announcement that manager Miki would be taking a leave of absence. Since the announcement, head coach Shiokawa has been serving as acting manager. Aiming for further progress, the team has brought in Mr. Yoshii as the new manager midway through the season. This marks an unusual timing for a new manager to be brought in from outside the organization.

Yoshii has amassed 121 wins in his combined career in Japan and the US, and as a coach, he has nurtured top-class pitcher such as Yu Darvish (Padres) and Shohei Ohtani (Dodgers). In 2022, he coached Roki Sasaki (Dodgers) as the pitching coordinator for the Lotte Marines. From 2023, he served as the manager of the Lotte Marines for three years, and in his first year as manager, he led the team from fifth place the previous year to second place.

New manager Yoshii's first game is expected to be against Lotte on the 19th (at ZOZO Marine Stadium), which will be the first game since the league resumed. Attention is focused on whether Rakuten Eagles 's unusual decision, spearheaded by owner Mikitani, will be a factor in changing the tide.
