How do you become a baseball manager?

There are many ways to become a manager for a baseball team. Yet, you have to start out by becoming a minor league coach, for example, a first base coach. The team owner will bring you up to a higher league. If the manager gets fired, you could be a candidate and the team owner will choose you. But you need experience in playing baseball first in the minor leagues by getting into a draft pick.

Play baseball, dude. At least through high school. Try to play as long as you can. Then, start coaching at any level available. Some private schools have a hard time getting real coaches. I know, I went to one! Be an assistant coach somewhere, work your way up. Get into the minor leagues as a coach after that. Get paid crap and drive around in a bus for years on end until you maybe can hang on and get a scouting post in the bigs, or a coaching gig in college. There's a ladder. Climb it. But you'll climb faster the longer you are a player.

Most coaches and managers start out as players. The besy coaches and managers are the lesser known utility players. Super Stars generally do not make good managers. No particular classes in school will prepare you to be a coach. Just make sure you study and get good grades and then stay close to the game and learn all you can. Maybe volunteer as an assistant coach on a high school or summer league team.

it helps if your a ex ball player now adays

but back in the old days you can work your way up from high school or minor league /colleage team

but i would rather be a ump than a manager
