Can you explain what it means to be a Free Agent in Major League Baseball?

Sure. There are four classes of Major League Baseball free agents, based on a player’s age and experience level, so there are four groups. We can divide them into four categories:

An unrestricted free agent is someone who is not under contract with any other team.

A Type-A free agent is a player who has been on the team’s roster for at least six years and has at least 10 years of service time. They have the highest compensation rights, which means their new team has to give them at least as much in compensation as they would have had if they had been a Type-A free agent the previous year. A team can only sign one Type-A free agent, and the one they sign gets to receive the Type-A bonus.

A Type-B free agent is a player who has been on the team’s roster for at least four years, with at least two years of service time, and is at least 26 years old and has at least three years of Major League service. Type-B free agents are still valuable players, but they don’t have the same compensation rights. A team can sign as many Type-B free agents as they want, and the free agents will share compensation,

Sure!  When a player signs with a new team, they get to choose which team they want to play for, rather than just being assigned to a team by their previous team.  In the US this is usually a good thing, as it can help players get more money and the ability to play for the team they prefer.  Sometimes a player can also choose which team they play for in Spring Training (early season training camps).
