In baseball, the field 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.

A head coach, senior coach, or manager is a professional at training and developing athletes. They typically hold a more public profile and are paid more than other coaches. In some sports, the head coach is instead called the "manager", as in association football and professional baseball. In other sports, such as Australian rules football, the head coach is generally referred to as the senior coach.
