Reds general manager Walt Jocketty in a year-end hash-out session about the team’s dissatisfying season told Baker he was intending to fire hitting coach Brook Jacoby, according to a person familiar with the situation. And that was all Baker had to hear.
Baker wasn’t the one who brought in Jacoby, but he also knew it wasn’t Jacoby’s fault. So Baker took the bold step that led to Jocketty ousting him as Reds manager.
