baseball manager

In baseball, the field manager (commonly referred to as the manager) is the equivalent of a head coach who is responsible for overseeing and making final decisions on all aspects of on-field team strategy, lineup selection, training and instruction. Managers are typically assisted by a staff of assistant coaches whose responsibilities are specialized. Field managers are typically not involved in off-field personnel decisions or long-term club planning, responsibilities that are instead held by a team's general manager.
